HZGR routing in MANET

An established route probably fails before the end of the transmission session in a wireless ad hoc network where mobility is high. Due to this level of mobility, routing protocols frequently require rerouting that imposes data latency and bandwidth overhead. In this paper, we propose a novel geographic routing protocol called HZGR. We design HZGR based on Greedy Forwarding (GF). This makes HZGR simple with low bandwidth overhead. We incorporate a number of mechanisms in HZGR to improve the performance of GF. Our simulation experiments show that HZGR improves the existing routing schemes such as GF and AODV in terms of bandwidth overhead and average path length under high mobility.
