In recent years IoT (Internet of Things) is gaining interest among researchers and many IoT development platforms, SDK’s have been proposed. There are lots of low powered, efficient devices available in market which can be used to create IoT solutions. The main drawbacks of IoT is that every manufacture proposed it owns protocol and provide their own API’s to work with it. You need to be an avid programmer to implement, understand, customized and use this API’s. Since lots of these libraries are open source not much information can be gathered online. To solve this protocol agnostic problem in IoT many researchers are now focusing on WoT i.e. Web of Things. The main advantage of implementing WoT is that we can use familiar Web protocols to build up our solutions. In this paper we will discuss SOA architecture, proposing a high level WoT network implementation at home-using embedded devices and Web protocols like REST web services and JavaScript to achieve interoperability. We will also discuss security concerns in WoT and best practices to avoid vulnerabilities.

Most of the HVAC system in home is running based on static control algorithm; based on fixed work schedules. In that old system energy became waste when home contains low or no people occupancy. In this paper we presented new dynamic approach of HVAC system control, by combined with pervasive computing. Pervasive computing can be defined as availability of centralized system and information anywhere and anytime. We achieved our target by using occupancy sensors for collecting home status. Initially our occupancy sensors collect human presence and current HVAC status details and stored in centralized system. Then based on our user defined threshold value the centralized system maintains the building's heating, cooling and air quality conditions by controlling HVAC devices. I.e. this system turned off HVAC systems when a home is unoccupied, or put the system into an energy saving sleep mode when persons are asleep.

Cognitive Radio (CR) technology has significant impacts on upper layer performance in Ad Hoc Networks (AHNs). In recent times, several number of investigation are conducted in CR are mostly focusing on the opportunistic spectrum admission and physical layer transmission throughput. However, CR technology determination also have considerable impacts in mobile Ad Hoc networks (AHNs), which enables wireless devices to dynamically create networks without essentially use of a fixed infrastructure . Nowadays, establishing a cognitive network is such a difficult task. The most important issues is routing in CRAHNs. In this paper, it majorly focuses on the survey of routing and opportunistic routing schema in CRAHN. The most significant scheme behind this concept is to make use of a suitable routing protocol designed for establishing Cognitive Radio Network (CRN). Due to licensing, the accessibility of radio frequency for wireless communication gets reduced day by day. Thus, there is a necessitate to have some other way to use these frequencies in an efficient manner. Routing is efficient method to solve these issues, but the use of geographical concept is also a challenging task in CRN. Since, there is a lack in detailed understanding of these extremely dynamic opportunistic links and a consistent end-to-end transportation mechanism over the network. Here, it focuses on the study of possible routing approaches with the purpose of be able to be employed in CRAHNs. There is a comparison on performance evaluation of various potential routing approaches in terms of table significant reduction and what solution can be found from the routing protocol are also discussed. The routing protocol attains reliable communications for CRAHNs, without usually getting feedback information from nodes in a CRAHN to considerably accumulate the communication overhead.

The topic of ‘‘the cloud’’ has attracted significant attention throughout the past few years. It allows resource sharing that includes software, platform and infrastructure by means of virtualization. Cloud Adoption in Oil & Gas companies have approached cloud with caution, but they are increasingly deploying cloud services. Energy companies have carefully weighed whether they should opt for a public cloud versus a private one, and which applications are fit for deployment via the cloud. For the most part, the industry has opted to use cloud for generic purposes. Generic business functions like payroll process and procurement are being run through the cloud, along with customer relationship management, likely through software-as-a-service offerings that have become well known. Security is as much of an issue in the cloud as it is anywhere else. Different people share different point of view on cloud computing. Some believe it is unsafe to use cloud. Cloud vendors go out of their way to ensure security. This paper aims to understand the effects of security and privacy concerns on educational use of cloud services. This proposed a research model based on Ajzen’s (1991) Theory of Planned Behavior (TPB). Following the TPB, the research developed a model, which posits that staff attitudes predicted by security and privacy perceptions and behavioral intentions are predicted by attitudes towards using cloud services. The Model was assess the based on the data collected by means of survey questionnaires. Results supported the proposed model, validating the predictive power of the TPB.

In recent years, WLANs are widely deployed everywhere due to the low-cost and easy installation. Selecting the best access point is the major research problem. The stations in the network should get associate with the suitable access points that results in higher throughput. In IEEE 802.11 wireless networks, the simple association strategy is to get associate to the AP with the strongest RSSI value, which may cause load imbalance and may eventually leads to traffic overhead. Access point selection is still a critical problem.So, a new metric or combination of metrics has to be derived that facilitates the effective selection of an AP to achieve better throughput.

In a wireless communication cellular network, call activity can be more intensive in some regions than others.These high-traffic regions are called hot spot regions. In typical deployments of wireless cellular networks, traffic hot spots can arise from the non-uniform geographic distribution of the mobile users, and the heavy-tailed nature of their network usage patterns. These hot spots of activity can degrade system performance, by increasing network utilization, wireless interference, call blocking, and even call dropping from failed handoffs for mobile users. In this paper, a hierarchical cellular communication wireless network is characterized by overlapping the service area for managing the new calls users having different mobility speed. The overlapping property of the hierarchical-network provides the advantages that share the traffic load to improve the performance of wireless cellular networks in the highly populated area where both slow speed users and high speed users are available. Picocells are created that are underlaid to two-tier networks for handling the slow or staying speed visitor (outside registered) users. The hierarchical-networks with picocells, microcells and macrocells provide the secondary resource, which provide the services to new calls as well as handoff calls with guard channels by overflow the slow speed visitor users in picocells, slow speed local users in macrocell by sharing the frequency in vertical as well as in horizontal directions. The picocell is installed on four wheeler vehicle may be moved at any place as per necessity and may be utilized to create picocell to handle the load of hot spot area. Such kind of picocell is known as Portable-Picocell (P-Picocell/ P2cell). The call loss probability of new calls is developed through numerical analysis. The proposed schemes are compared with the existing schemes of CAC. Results show that new proposed schemes are more efficient and handle more visitor calls by redirecting calls and sharing of load in P2cell.

The Wireless sensor networks (WSN) consisting of a large number of sensors that are effective for gathering data in a variety of environments, as the sensor operate on battery which is of limited power. To support high scalability and better data aggregation in fixed base station communication, sensor nodes are often grouped into disjoint, non overlapping subsets called clusters. Clusters create hierarchical WSN which incorporate efficient utilization of limited resources of sensor nodes. These clusters are formed by specialized cells. Each cluster is managed by a special node called cluster head and advanced node. An algorithm for better cluster head selection based on the node energy and the distance from base station to the cluster head for the efficient transmission and to reduce energy consumption by the sensor nodes is proposed in this paper. And the same algorithm is compared with the LEACH algorithm in terms of energy consumption.

As network size continues to grow exponentially, there has been a proportionate increase in the number of nodes in the corresponding network. With the advent of Internet of things (IOT), it is assumed that many more devices will be connected to the existing network infrastructure. As a result, monitoring is expected to get more complex for administrators as networks tend to become more heterogeneous. Moreover, the addressing for IOTs would be more complex given the scale at which devices will be added to the network and hence monitoring is bound to become an uphill task due to management of larger range of addresses. This paper will throw light on what kind of monitoring mechanisms can be deployed in internet of things (IOTs) and their overall effectiveness.

Multi-Protocol Label Switching is an emerging technology which is the initial step for the forthcoming generation of Communication. It uses Labels in order to identify the packets unlike the conventional IP Routing Mechanism which uses the routing table at each router to route the packet. There exits certain methods which are used to recover the failure of any link and/or node failure in the given Network. It uses the techniques of FRR with the help of RSVP/CR-LDP to overcome the link and/or node failures in the network. On the other hand there are certain limitations/Drawbacks of using the above mechanisms for Failure Detection and Recovery which are multiple protocols such as RSVP/CR-LDP over OSPF/IS-IS and complex algorithms to generate backup path since each router works individually in order to create a backup tunnel. So to overcome the listed limitations, this paper discusses a relatively new technique for MPLS Network which is Source Routing. Source Routing is the technique in which the source plays the role of directing the packet to the destination and no other router plays the role of routing the packet in the network. Using OPNET Modeler 17.5 tool for implementing source routing when there is a network failure is performed and the results are compared by implementing RSVP/CR-LDP over the same failed network.

Fault Tolerance Techniques facilitate systems to carry out tasks in the incidence of faults. A checkpoint is a local state of a process saved on stable storage. In a distributed system, since the processes in the system do not share memory; a global state of the system is defined as a combination of local states, one from each process. In case of a fault in distributed systems, checkpointing enables the execution of a program to be resumed from a previous consistent global state rather than resuming the execution from the commencement. In this way, the sum of constructive processing vanished because of the fault is appreciably reduced. In this paper, we talk about various issues related to the checkpointing for distributed systems and mobile computing environments. We also confer various types of checkpointing: coordinated checkpointing, asynchronous checkpointing, communication induced checkpointing and message logging based checkpointing. We also present a survey of some checkpointing algorithms for distributed systems.

False data injection attack is a serious threat to wireless sensor network. In this paper, a node legitimacy based false data filtering scheme (NLFS) is proposed. NLFS verifies not only message authentication codes (MACs) contains in reports, but also the legitimacy of nodes that endorse the report. The verification guarantees that compromised nodes from different geographical areas cannot collude to inject false data, which makes NLFS has a high tolerance of compromised nodes. In addition, NLFA only utilizes the relationships between node IDs to verify the legitimacy of nodes without other software or hardware overhead. Simulation results show that NLFS can filter 95% false reports within three hops and is resilience to an increasing number of compromised nodes.

Mobile cloud computing is the revolutionary distributed computing research area which consists of three different domains: cloud computing, wireless networks and mobile computing targeting to improve the task computational capabilities of the mobile devices in order to minimize the energy consumption. Heavy computations can be offloaded to the cloud to decrease energy consumption for the mobile device. In some mobile cloud applications, it has been more energy inefficient to use the cloud compared to the conventional computing conducted in the local device. Despite mobile cloud computing being a reliable idea, still faces several problems for mobile phones such as storage, short battery life and so on. One of the most important concerns for mobile devices is low energy consumption. Different network links has different bandwidths to uplink and downlink task as well as data transmission from mobile to cloud or vice-versa. In this paper, a novel optimal link selection algorithm is proposed to minimize the mobile energy. In the first phase, all available networks are scanned and then signal strength is calculated. All the calculated signals along with network locations are given input to the optimal link selection algorithm. After the execution of link selection algorithm, an optimal network link is selected.

We address the problem of malicious node detection in a network based on the characteristics in the behavior of the network. This issue brings out a challenging set of research papers in the recent contributing a critical component to secure the network. This type of work evolves with many changes in the solution strategies. In this work, we propose carefully the learning models with cautious selection of attributes, selection of parameter thresholds and number of iterations. In this research, appropriate approach to evaluate the performance of a set of meta classifier algorithms (Ad Boost, Attribute selected classifier, Bagging, Classification via Regression, Filtered classifier, logit Boost, multiclass classifier). The ratio between training and testing data is made such way that compatibility of data patterns in both the sets are same. Hence we consider a set of supervised machine learning schemes with meta classifiers were applied on the selected dataset to predict the attack risk of the network environment . The trained models were then used for predicting the risk of the attacks in a web server environment or by any network administrator or any Security Experts. The Prediction Accuracy of the Classifiers was evaluated using 10-fold Cross Validation and the results have been compared to obtain the accuracy.

In the recent trend steganography plays an important role in providing secrecy in internet. Steganography works by replacing bits of useless or unused data in regular computer files with bits of different, invisible information. Cryptography is used to scramble the information sent and make it as a scrambled text which is not understandable. Steganography is used to hide the information so that secrecy can be established. If Steganography and Cryptography are used together it has more advantage for providing security for the information. In this paper hiding of data in digital images formation carried out using adaptive hiding with the optimum pixel adjustment (OPA) algorithm. Resultant system evidences remarkable hiding rates with other Steganographic systems.

The concepts of secure transactions are essential for almost all online transaction. Generally such methodologies were adapted in recent days using one time password. The one time password is a random password generated by the server send to the user for their person authentication access. In contract with the traditional approach the work addresses the concept of two factor authentication for accessing and approving the one time password by the legitimate user. This works on all platforms and applications that are either may be online processed transaction done via system or electronic gadgets. This work will add additional secure measure despite the security poised by the one-time password. Also the work neglects the processing of automatic server processing by implementing the concept of self-reliable code that is generally termed as capcha code.

Pattern recognition has its roots in artificial intelligence and is a branch of machine learning that focuses on the recognition of patterns and regularities in data. Data can be in the form of image, text, video or any other format. Under normal scenario, pattern recognition is implemented by first formalizing a problem, explain and at last visualize the pattern. In contrast to pattern matching, pattern recognition algorithms generally provide a fair result for all possible inputs by considering statistical variations. Probabilistic classifiers have supported Agricultural statistical inference for decades. Potential applications of this technique in agriculture are numerous like pattern recognition from satellite imagery, identifying the type of disease from leaf image, weed detection etc. This paper explores employment of pattern recognition in an agricultural domain.
