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.

Corpus development gained much attention due to recent statistics based natural language processing. It has new applications in Language Technology, linguistic research, language education and information exchange. Corpus based Language research has an innovative outlook which will discard the aged linguistic theories. Speech corpus is the essential resources for building a speech recognizer. One of the main challenges faced by speech scientist is the unavailability of these resources. Very fewer efforts have been made in Indian languages to make these resources available to public compared to English. In this paper we review the efforts made in Indian languages for developing speech corpus for automatic speech recognition.

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.

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.

Internet has played a drastic change in today’s life. Especially, web browsing has become more exclusive in compact devices. This tempts the people to migrate their innovations & skills into an unimaginable world. With these things in mind, it is necessary for us to concentrate more on the techniques that how the web data’s are accessed and accounted. Developed countries use a widely popular technique called Flat- rate pricing, which is solely independent on data usage. But whereas, developing countries are still behind the concept of “pay as you use”, which leads to high usage bills.With an effort to resolve the problem of high usage bills, we propose a cost effective technique, which reduces the data consumption in web mobile browsing. It reduces the usage bills in the mechanism of usage-based pricing. The key idea of our approach is to leverage the data plan of the user to compute a cost quota for each web request and a network middle-box to automatically adapt any web page to the cost quota. Here we use a simple but effective content adaption technique that highly decides which image or data best fits the mobile display with low cost and high quality resolution. It also emphasis on the trendy technique,” The Data Mining “which mines the requested & required data. The mined data’s are filtered based on the content adaption technique and fit into the display effectively. Interesting and noticeable feature in this concept is that only important web contents requested by the user are exhibited. A feedback process involves in this concept to retrieve the required data alone and also to improve the best fit resolution. With this proposed system web mobile browsing becomes cheaper & contributes an enormous logic for the future project in the field of Mobile browsing.

Traffic management and congestion control are major issues in Asynchronous Transfer Mode(ATM) networks. Congestion arises when traffic in the network is more than offered load. The primary function of congestion control is to ensure good throughput and low delay performance while maintaining a fair allocation of network resources to users. In this paper, Enhanced Proportional Rate based Congestion Avoidance (EPRCA) scheme proposed by ATM forum has been considered. But this scheme has limitation of higher cell drop problem for the bursty traffic. Improvements to EPRCA scheme have been proposed to reduce cell drop problem and results of improved EPRCA schemes were analyzed with basic EPRCA scheme.

There have been numerous works on network intrusion detection and prevention systems, but work on application layer intrusion detection and prevention is rare and not very mature. Intrusion detection and prevention at both network and application layers are important for cyber-security and enterprise system security. Since application layer intrusion is increasing day by day, it is imperative to give adequate attention to it and use state-of-the-art algorithms for effective detection and prevention. This paper talks about current state of application layer intrusion detection and prevention capabilities in commercial and open-source space and provides a path for evolution to more mature state that will address not only enterprise system security, but also national cyber-defence. Scalability and cost effectiveness were important factors which shaped the proposed solution.

SDN (Software Defined Networking) is the networking architecture that has gained attention of researchers in recent past. It is the future of programmable networks. Traditional networks were very complex and difficult to manage. SDN is going to change this by offering a standard interface (OpenFlow) between the control plane and the networking devices (data plane). Its implementation is fully supported by software so that we can control the behavior of networking devices through programmatic control. This programmatic control provides various new ways to find breakpoints and failures in networking devices. Today SDN has become an important part of networking, so it is important to emulate its behavior. SDN support virtualization which makes it scalable and flexible. Data traffic resides in the data plane. The main function of intelligent controller is to decide the routing policy and manage the traffic in data plane. So effectively SDN emerges as a networking architecture that has the ability to solve all problems those were found in traditional architecture In this paper the authors discussed historical perspective of SDN, languages that support SDN, emulation tools, security issues with SDN and advantages that makes SDN suitable choice for today’s network.
