Directional Greedy Routing Protocol (DGRP) in Mobile Ad-Hoc Networks
Position based routing protocols are becoming popular over topology based routing protocols due to advancement and availability of GPS devices. Most of the existing position based routing protocols depends upon the beacon interval to collect its current position due to limitations of GPS systems. Delay in collecting the current position forces the routing protocol to use inaccurate position information in highly mobile network that leads to low throughput and high overhead. So in this paper we propose a directional greedy routing protocol (DGRP) which predicts the position of it neighboring nodes during the beacon interval, using the speed and direction information provided in beacon packets. Simulation result in ns2.31 shows that DGRP achieves the better packet delivery ratio, throughput, and overhead compared to the existing GPSR protocol.
