LDAB-GPSR: Location PreDiction with Adaptive Beaconing – Greedy Perimeter Stateless Routing Protocol for Mobile Ad Hoc Networks

In mobile ad-hoc networks (MANET), nodes are randomly distributed and move freely, hence the network may face rapid unexpected topological changes. this paper, an improved greedy perimeter stateless routing protocol, called “LDAB-GPSR”, is proposed. LDAB-GPSR mainly focuses on maximizing packet delivery ratio while minimizing control overhead. order to accomplish this, two techniques introduced, first one location prediction technique in which forwarding strategy by choosing more stable routes for data forwarding. The second adaptive beaconing slow start algorithm employed adapt beacon interval time based mobility of traffic load instead using periodic strategy. These strategies together improve overall performance GPSR protocol. new proposed protocol evaluated carrying out several NS-2.35 simulation experiments. results show that outperforms GPSR+Predict terms ratio, overhead, end delay, throughput. ratios enhancement approaches 40%.
