The Performance of the Extended DSDV ( eDSDV ) MANET Routing Protocol and its Suitability in Integrated Internet-MANET

In this paper, an extended version DSDV (eDSDV) Protocol is proposed for Ad Hoc networks. eDSDV overcomes the problem of stale routes, and thereby improves the performance of regular DSDV. The proposed protocol has been implemented in the NCTUns Simulator and performance comparison has been made with regular DSDV. The performance metrics considered are packet-delivery ratio, end-end delay, dropped packets, routing overhead, route length. It has been found after analysis that the performance of eDSDV is superior to regular DSDV under different simulation scenarios. The proposed protocol is an extension of DSDV in terms of two-hop route-requests packets and dynamic buffer management algorithm which is used to avoid discarding of packets in case when the buffer associated with the destinations becomes full. Later in the paper an architecture for integrating MANET with Internet using eDSDV is presented KeywordsMobile Ad Hoc Network (MANET), Routing, eDSDV, NCTUns
