A DYNAMIC POSITION BASED ROUTING PROTOCOL TO OPTIMIZE PACKET DELIVERY IN MOBILE ADHOC NETWORK

Abstract

Mobile Ad hoc networks (MANET) carried out multi-hop communication in an environment with no fixed infrastructure, by means of mobile nodes and changing network topology. In the earlier period, hundreds of new routing protocols were designed for the various scenarios of MANET. Most existing ad hoc routing protocols are liable to node mobility, especially for large-scale networks. Provoked by this issue, this paper presents the new approach a Dynamic Position Based Routing (DPBR) protocol which implemented in the distributed architecture and takes advantage of the stateless property of geographic routing and the broadcast nature of wireless medium dynamically. When a data packet is sent out, some of the neighbor nodes that have eavesdropped with the transmission will serve as forwarding candidates, and take turn to forward the packet if it is not in a position to receive. By utilizing such uphill backup, this paper concentrate on how the new examine model supports to reduce the packet drop as well as increase delivery ratio dynamically. The additional latency earn by local route recovery is greatly reduced and the duplicate relaying caused by packet reroute is also decreased. Both theoretical analysis and simulation results show that DPOR achieves excellent performance even under high node mobility with acceptable overhead.
