<p>The Internet of things (IoT) is a major source for technology solutions in many industries. The IoT can consider, Wireless Sensor Network (WSN) as the backbone network to reduce formation or advent of new technology. Integration of these would reduce the burden and form smart sensor node network with nodes given access to internet. WSN is already a major legacy system that has percolated into many industries. Thus by integration of IoT and WSN no huge paradigm shift is needed for the industries.</p>

A mobile Ad Hoc network is a Noinfrastructure networkand randomly moves nodes are presented .Multicasting support data forwarding, and thus it is suitable for MANETs.Implementing'Multicast opportunistic cooperative routing in Mobile Ad Hoc Network', (MANET) to improves the %PDR , and reduces the power consumption, multicast is meant for group communication. Multicasting sending copy of the information to all members in a group, it improves, the wireless link in a network.In an Ad Hoc network nodesare randomly distributed and free to fly without any existing infrastructure or infrastructure less administration. In the Networkeach node isfitted out with a single omnidirectional antennaand that multiple nodes are allowed, together their transmissions to take the advantages of spatial diversity to obtain energy savings.It is assumed that some nodes are not a member in a group, hence it does not receive transmission, a nd packet has be resent again. Where as in existing unicast transmission protocol for multiple hop network picked by multiple intermediate nodes,and only one receiver. Theprotocol performance is analyzed using the ns-2.32 network simulator.

-Privacy control mechanism based on policy frameworks that are rich in semantic web technologies to control information flow in social networking applications. The privacy control mechanism Provides users of the system better control while sharing information than the state of the art systems Combines dynamic user context, For instance, current time, current location or current activity of the user Online social networking is viewed by many as the next new paradigm in personal, professional and organizational networking and marketing. (Social media are the tools that people use to do social networking, such as Facebook, LinkedIn and Twitter.) The following sections first give a broad overview of the movement of social networking, including basics about each of the most popular tools. The next section describes how to use the tools for personal, professional and organizational networking and marketing.
