COR-HR: an efficient hybrid routing approach using coefficient of restitution in MANET

The rapid expansion of mobile technology and real time applications partake strictly to support quality of service (QoS) such as throughput, delay, energy consumption, jitter etc. Mobile technology like MANET experiences frequent and randomly changing network topology. A major challenge is to design QoS based congestion free routing algorithm in MANET. The paper presents a novel, hybrid routing protocol driven by the principles of Newtonian Mechanics. We select the shortest paths and nodes based on the residual energy state of the nodes enabling the protocol mitigate the problem of congestion. Path selection and congestion control are handled by the values calculated by using a physics based concept namely the Coefficient of Restitution. The simulation results show that the protocol provides reasonably good benchmarks of Quality of Service (QoS) in terms of end to end delay, packet delivery ratio and throughput.
