MANETs Using Advance DSR Algorithm and Improve the Secure Transmission

In Wireless communications the traffic across a mobile ad hoc network (MANET) can be highly vulnerable to security threats. The mobile ad hoc networks are more prone to suffer from the malicious behaviors than the traditional wired networks. Therefore, it becomes very much necessary to pay more attention to the security issues in the mobile ad hoc networks. For this we are using DSR protocols. This Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. The protocol is composed of the two main mechanisms of "Route Discovery" and "Route Maintenance". The presence of malicious node will interrupt the packets and causes unwanted changes. In order to avoid these problems signature verification is done at every hop using new algorithm. This algorithm increases the amount of data received with respect to time and increases the throughput.
