COMPARISON OF RAODV AND AODV NETWORKING ROUTING PROTOCOLS BASED ON NUMBER OF HOPS IN PATH

摘要

In mobile ad hoc networks, mobile devices wander autonomously for the use of wireless links and dynamically varying network topology. AODV (Ad-hoc On-demand Distance Vector routing) and most of the on demand ad hoc routing protocols use single route reply along reverse path. Rapid change of topology causes that the route reply could not arrive to the source node. This increases communication delay and power consumption as well as decrease in packet delivery ratio. To avoid these problems, a Reverse AODV (RAODV) was proposed which tries multiple route replies. It reduces path fail correction messages and obtains better performance than the AODV. Remained energy in RAODV is higher than AODV; even it has sent more data packets to destination. A simulation study is presented to compare these two protocols. Results shows in RAODV the data packets meet fewer hops in chosen path and this will effect on remind energy in RAODV to be higher than AODV.
