An Improved Reactive Routing Protocol over Mobile Ad-hoc Networks
Khalid Ahmad Darabkh, Mohammad S.A. Judeh · 2018
In this article, a new reactive routing protocol is proposed which is considered as a major extension of Ad-hoc On-demand Distance Vector (AODV) routing protocol, namely, Mobility Aware and Dual Phase Ad-hoc On-demand Distance Vector with Adaptive Hello Messages. It primarily concentrates on building routes considering nodes' speeds and direction of motion with respect to source nodes, thereby establishing more stable routes and reducing the route breakages. Moreover, we proposed an adaptive control packet announcement mechanism, which is directly connected to the periodic hello messages approach, with nodes' speeds, yielding a significant reduction in the amount of control overhead and congestion over the network. Our protocol is evaluated in terms of packet delivery ratio, control overhead, end-to-end delay, and energy consumption.
