Randomness studies of bit sequences, created either by a ciphering algorithm or by a pseudorandom bit generator are a subject of prolonged research interest. During the recent past the 15 statistical tests of NIST turn out to be the most important as well as dependable tool for the same. For searching a right pseudorandom bit generator from among many such algorithms, large time is required to run the complete NIST statistical test suite. In this paper three test modules are considered in succession to reduce the searching time. The module-1 has one program and is executed almost instantly. The module-2 has four programs and takes about half an hour. The module-3 has fifteen programs and takes about four to five hours depending on the machine configuration. To choose the right pseudorandom bits generator, the algorithms rejected by the first module are not considered by the second module while the third module does consider only those passed by the second module.

In IEEE 802.11 based wireless mesh network (WMN), a mesh client often finds multiple access points (AP) to associate with. How to select the best AP is the open research problem. The traditional AP selection method defined by IEEE 802.11 standard is based on received signal strength. This method is proven inefficient as it does not consider many important factors such as channel conditions, AP load, etc. Many alternate solutions have been proposed so far in the literature, but they are all focused on wireless local area network (WLAN) environment. As there are significant differences between WLAN and WMN, all these proposed association mechanisms must be redesigned to fit into WMN environment. This paper studies the AP selection problem in the context of WMN. We critically analyze the existing work and identify technical challenges involved in AP selection problem. This paper also provides directions to design the metrics of AP selection method in WMN.

Wireless network has come out as one of the key enablers for reliable data delivery for different types of applications.Ad-hoc network consists of self-actuated node that collaborates in order to transfer the information.Trajectory-based Statistical Forwarding (TSF) method used optimal target point selection algorithm to forward packets in order to satisfy probability of packet delivery over multi-hopbut failed provide higher throughputon the multipath data delivery. TheVoid Aware Pressure Routing (VAPR) method used hop count and intensity information to build a directional data delivery system but performance of specialized geographic routing based multipath data delivery was not attained. To maintain the higher throughput level on ad-hoc network data delivery, Median Multicast Throughput Data Delivery (MMTDD) mechanism is proposed in thispaper.The basic idea of MMTDD mechanism is to divide a message into multiple shares and deliver them via multiple independent source paths to the destination. MMTDD mechanism with the average time standard takes the best threshold value for every data (i.e.,) packet partitioning by avoiding packet loss. By this means, MMTDD mechanism uses the Average Time Standard (ATS) to guarantee the required packet allocation with higher throughput level. With the application of ATS, the MMTDD mechanism derives the theoretical model by attainingapproximately 4% higher throughput level on the multipath data delivery in ad-hoc network.MMTDD mechanism makes use of time scheduling schemes to discover and maintain data delivery paths with minimal time consumption.Median Multicast in MMTDD mechanism used the balanced state flow model to deliver data on multiple paths and experiment is conducted on factors such as time consumption, data delivery rate,average delivery delay and throughput level.

Customer Relationship Management (CRM) is a technical jargon which is a blend of methodologies, software and internet, which are used by a company to achieve its goal through the identification and satisfaction of customer’s stated and unstated needs and wants. This software addresses customer life cycle management. This system manages company interactions with current and future customers. It involves technology to organize, automate and synchronize business processes. CRM application is an essential tool for a company to grow and help to increase the satisfaction of customers. There are many benefits of CRM; those make the market environment customer centric. In this paper, we reviewed previous studies and identify those benefits which affect customers and company both. But CRM has many problems also because of them CRM gets failure. Its failure rate is more than its success rate. We also elaborated its failure factors and along with them its critical success factors which help in making CRM a successful project for a company, however implementation of CRM is a complex task.

The problem with limited numbers of physicians, nurses, and other healthcare providers is expected to exacerbate. Health care must be as efficient as possible. This situation provides an opportunity for the application of telehealth clinics. It is time for organizations providing health care to objectively consider telehealth clinics. Information and communication technologies (ICTs) have great potential to address some of the challenges faced by both developed and developing countries in providing accessible, cost-effective, high-quality health care services. Telemedical clinics use ICTs to overcome geographical barriers, and increase access to healthcare services. This is particularly beneficial for rural and underserved communities in developing countries – groups that traditionally suffer from lack of access to health care. In this work we propose an equipped system with new technology to provide wide range of services in Telemedical clinics which facilitates the provision of medical aids from a distance. It is an effective solution for providing specialty healthcare in the form of improved access and reduced cost to the rural patients and the reduced professional isolation of the rural doctors. Telemedical clinics can enable ordinary doctors to perform extra-ordinary tasks.

Long Term Evolution (LTE) system adapts advanced Multiple Input Multiple Output (MIMO) antenna techniques on both uplink and downlink to achieve high peak data rates and higher system throughput. This enables LTE to support multimedia applications beyond web browsing and voice, which demands higher bandwidth configurations. LTE employs Orthogonal Frequency Division Multiple Access (OFDMA) in downlink to support spectrum flexibility in order to use upto 20MHz system bandwidth to improve the system throughput and robustness. Therefore the combined study of multi-antenna techniques and spectrum flexibility usage on the performance of LTE system becomes vital. Hence in this paper, an attempt has been made to evaluate the performance of different multi-antenna techniques with various system bandwidth configurations from 1.4MHz to 20MHz using QualNet 5.2 network simulator. The multi-antenna techniques considered for performance evaluation are Single Input Single Output (SISO), Multiple Input Single Output (MISO) and Multiple Input Multiple Output (MIMO). The performance metrics such as aggregate bytes received, average throughput, average delay and average jitter are considered for simulation study.

Human health is the real wealth for a society. Consequently prevention of health from complex diseases like cancer needs the diagnosis of these entire viruses at an early stage. Colon cancer, the most common one, reached the highest rate among all the other types recently. Colorectal cancer gets developed either in colon or in the rectum inside the large intestine, due to the abnormal growth of the cells. Computer-aided decision support system has become one of the major research topics in medical imaging field during the past two decades to detect cancers. Detecting and screening of colorectal cancers are done by a Computed Tomography. The implemented algorithm determines the locations and features of glands which are affected by cancer tissues and save this information for the subsequent diagnosis. The proposed algorithm carries out the diagnosis with two modules: One known as the gland detection and the other one referred as the nuclei detection. Gland detection is performed in the proposed algorithm using color segmentation either through HSV or LAB transformation. Noise removal and erosion of the input image is performed for enhancing the selection of the affected tissues. The boundary detection and connection is established through Markov Chain model to identify the affected tissues with proper threshold. The first module detects the glands where the possibly of miss detection is more. Hence to remove the miss detected glands the algorithm proceed for the second module referred as nuclei detection. The most well known region growing methodology is slightly modified to increase the speed and reduce the memory size To provide the execution in low-end clients, the whole image is cracked into smaller tiles and after the processing of each individual tiles , the results are to be merged to get back the original size. After nuclei detection if the number of nucleus is more that glands are miss detected glands and they are removed.

The recent surge in cloud computing arises from its ability to provide software, infrastructure, and platform services without requiring large investments or expenses to manage and operate them. Clouds typically involve service providers, Infrastructure / resource providers, and service users (or clients). They include applications delivered as services, as well as the hardware and software systems providing these services. Our proposed framework for generic cloud collaboration allows clients and cloud applications to simultaneously use services from and route data among multiple clouds. This framework supports universal and dynamic collaboration in a multi cloud system. It lets clients simultaneously use services from multiple clouds without prior business agreements among (CSP) cloud service providers, and without adopting common standards and specifications.

The emergence of OpenFlow-capable switches de- couples control plane from the data flow plane so that they support programmable network and allow network administrators to have programmable central control of network traffic via a controller. The controller and its communication with switches and users become a malicious attack target. This paper explores major possible security threats and attacks on the controller of SDN and proposes a new approach to automatically and dynamically detect and monitor malicious behaviors on flow message passing and defend such attacks to ensure the security of SDN. We have built a FlowEye prototype at service level on Mininet API, and simulation tests are done on two feasible attacks on OpenFlow Beacon platform. The paper provides the feasibility study of such attacks and defense protection strategies in SDN security research.
