Abstract

The focus of this paper is on securing the Route Discovery process in DSR, by extending association between the nodes involved in route discovery process. Dynamic Source Routing protocol shows unexpected behavior with multiple data streams under heavy traffic load when sent to common destination. It will cause congestion. In the current design, the routing protocol (DSR) is not congestion adaptive. The way in which the congestion handled by the DSR results in longer delay, more packet loss. When a new route is needed the routing protocols take significant overhead in finding it. In this paper we also prevent congestion from occurring in the first place and make DSR be congestion adaptive too. There by we are providing novelty by adding security and congestion adaptiveness to increase the service and quality of Dynamic Source Routing protocol in MANET.
