The Improved Overhearing Backup AODV Routing Protocol in MANET Network

Mobile ad-hoc network (MANET) is one of the most widely-used networks, which has attracted attentions for having features such as limited energy resources, limited bandwidth, and security weaknesses due to lack of a central infrastructure. Safe and suitable routing is one of the research aspects of MANET.In this paper, a proposed method, called M-AODV, which is a type of overhearing backup routing protocol, based on AODV, is presented. The simulation results of this protocol, in two different scenarios based on different nodes and different pause time, applied by NS2 simulator, showed the improvement of packet delivery rate and reduction of overhead and delay
