Wireless networks adapt easily to changes and offers flexibility in the configuration of the network. In MANET, each node will change its location dynamically and configure itself according to the environment. An effective mechanism for route discovery in such networks is broadcasting, but routing overhead associated with broadcasting can be large in high dynamic networks. To reduce this routing overhead in MANETs, a neighbor coverage based probabilistic rebroadcast protocol is used. To determine the rebroadcast order, a novel rebroadcast delay is used and it obtains the more accurate additional coverage ratio by sensing neighbor coverage knowledge. The rebroadcast probability is calculated by merging the additional coverage ratio and connectivity factor. In the proposed method Energy Efficient Neighbor Coverage Protocol(EENCP) is introduced. In this, the node does not forward RREQ unless there is sufficient energy (battery lifetime), and until the node density in its surrounding exceeds a particular threshold. These two parameters are defined taking into consideration various statistics. EENCP analyzes these two parameters, when implementing routing discovery, and avoiding the unnecessary information sending efficiently and avoid unnecessary information transfer.

In this paper, we present the idea of an ‘Analytic Search Engine Model’ that utilizes the regularly generated social media data for opinion formation. It combines the user ratings from different SNS platforms and analyzes them to form a collective opinion about a local business and ranks results in terms of this opinion formation, which ensures the reliability and quality of search results. This new mode of ranking web pages is termed as social rank, which is explained in this paper in details. It also gives the introduction to analytic search engine model, its architecture and the problems it may meet in future are presented.

Mobile Ad hoc networks (MANET) allow a set of wireless hosts to exchange information without any special infrastructure. The projct entitled “ Energy Optimization in Manets using On-Demand Routing Protocol” motivates the need for energy management in ad hoc wireless networks. Limited battery power is one of the most important issues in mobile ad hoc network as the mobile nodes operate in limited battery power. Also there occurs a problem of broken links due to the lack of energy which cause disorder in network system. Such problem occurs due to the unawareness of energy of mobile neighbor nodes. This paper presents the implementation of Adaptive HELLO messaging scheme to determine the local link connectivity information for monitoring the link status between nodes along with the incorporation of Dynamic On Demand Routing Protocol to reduce the energy consumption of mobile nodes to certain extent.

Wireless sensor networks (WSN's) have become the part and parcel of our life. The Wireless sensor networks are used to sense and process data in applications like Water Level Monitoring, Vehicle Tracking and Patient Health care Monitoring systems. The energy is supplied to the sensor node through the battery. As the battery storage cannot be retained for longer time, the sample of information may not be collected continuously and send to the Base Station with a regular interval of time. The collection of information and its processing will be difficult, as there would be dynamic change in topology due to failure of existing nodes, addition of new nodes, link failure, change in parameters and the amount of battery storage capacity left in nodes. The Sensor nodes must observe the context, identify the dynamic changes and adapt to the new operating conditions. The challenges to be addressed during the establishment of an infrastructure-based reconfigurable Wireless Sensor Networks are Localization, Software Development, Role Assignment, Design of Code Dissemination Algorithms, Routing, Reconfiguration Model, Configuration Management and Security. Many Frameworks have been proposed to establish an infrastructure-based Wireless Sensor networks. But, there exist a need for an adaptive infrastructure-based reconfigurable framework which has to reconfigure at the runtime.

In the real world the Scheduling of Jobs in industries is provided without any idle time which is very tedious. Practically it becomes difficult when any of the spare part has started to malfunction and has to be changed in the machine then some idle time is needed in order to undergo the change. In this proposed work some amount of idle time is allotted to schedule the jobs in a single machine which includes three stages namely scheduling strategy, inserting idle time and optimizing the net penalty value of all the jobs.

Network life time is the main concern area in wireless sensor network (WSN). Design energy efficient routing algorithm to prolong the network lifetime becomes one of the most important tasks in wireless sensor networks. There are many clustering approaches that were used earlier to enhance the network lifetime. Here, in this paper we have developed a LEACH-P (Leach-Modified) protocol to boost the overall lifetime of the wireless sensor network, that combines the idea of LEACH (Low Energy adaptive protocol) and SEP (Stable Election Protocol) together. LEACH-P basically based on the concept of heterogeneous clustered wireless sensor network, in which energy level of every node is not alike. We have equipped some percentage of total nodes with more energy. We have compared the result of LEACH, MTE and LEACH-P in our simulation and the simulation results show that the performance of LEACH-P is better than both LEACH and MTE.

Cloud outpouring is careful when an information distributor has given sensitive data to a set of trusted agents and few o f the information is leaked and found in an unauthorized place. An enterprise data leak may be a scary proposition. Security practitioners always deal with data cloud leakage issues that arise from various ways like e-mail and different net channels. In case of information cloud leakage from trusted agents, the distributor should assess the probability that the leaked information came from one or more agents. The proposed system can identify those parties who are guilty for such cloud leakage even once the data is altered. For this the system will use data allocation ways are also can inject “realistic but fake” information records improve the identification of cloud leakage. Moreover, data can also be leaked from inside an organization through e-mail. Hence there's also a need to filter these e-mails, may be done by blocking e-mails that contain pictures, videos or sensitive data in an organization. A principle utilized in e-mail filtering is classify e-mail based mostly the fingerprints of message bodies, the white and black lists of mail addresses and the words specified to spam.

Social Semantic Web Mining

The past ten years have seen a rapid growth in the numbers of people signing up to use Web-based social networks (hundreds of millions of new members are now joining the main services each year) with a large amount of content being shared on these networks (tens of billions of content items are shared each month). With this growth in usage and data being generated, there are many opportunities to discover the knowledge that is often inherent but somewhat hidden in these networks. Web mining techniques are being used to derive this hidden knowledge. In addition, the Semantic Web, including the Linked Data initiative to connect previously disconnected datasets, is making it possible to connect data from across various social spaces through common representations and agreed upon terms for people, content items, etc. In this book, we detail some current research being carried out to semantically represent the implicit and explicit structures on the Social Web, along with the techniques being used to elicit relevant knowledge from these structures, and we present the mechanisms that can be used to intelligently mesh these semantic representations with intelligent knowledge discovery processes. We begin this book with an overview of the origins of the Web, and then show how web intelligence can be derived from a combination of web and Social Web mining. We give an overview of the Social and Semantic Webs, followed by a description of the combined Social Semantic Web (along with some of the possibilities it affords), and the various semantic representation formats for the data created in social networks and on social media sites. Provenance and provenance mining is an important aspect here, especially when data is combined from multiple services. We will expand on the subject of provenance and especially its importance in relation to social data. We will describe extensions to social semantic vocabularies specifically designed for community mining purposes (SIOCM). In the
