Performance Improvement of Wireless Mobile by DSR

To achieve this one has to concentrate on the routing protocol. Transmission Control Protocol (TCP) is the dominating end-to-end transport layer protocol which provides secure and reliable data transfer together with some other protocols in the protocol stack Recent works in transport protocols for ad-hoc networks have investigated the impact of ad-hoc network characteristics on TCP’s performance, and proposed schemes that help TCP overcome the negative impact of such characteristics as random wireless loss and mobility. Its performance is good in wired networks where packet losses are due to congestion. If standard TCP is applied on wireless networks its performance degrades. We briefly outline the different factors below In this paper, we contend that existing approaches to improve TCP performance over mobile ad-hoc networks have focused only on a subset of the factors affecting TCP performance by Symmetric Route Pinning (SRP). We identify a comprehensive set of factors, aimed at improving performance by SRP they reduces the probability of a connection stalling through route failures, predicting route failures before they occur and minimizing the latency for route error propagation.
