A Robust Ad hoc Reactive Energyconstraint Multi Path routing protocol for High Mobility Networks

摘要

Existing routing metrics in mobile ad hoc networks are limited to avoid link failures either due to insufficient battery power or high speed of node. Thus, these routing metrics are not able to capture network characteristics completely. This paper proposes a new robust multi path routing protocol for high mobility and scalable ad hoc networks, RARE?MP. It selects route based on the value of Node Reliability Factor which is a function of residual energy, speed and hop count. The key idea of protocol is to compute nodal reliability factor of route in path selection process and sort multiple path by descending nodal reliability factor. In essence, whenever a new route with higher nodal reliability factor is available, data packets are forwarded through a new emerging route. It balances the nodal battery power utilization and reduces the link failures leading to increase the overall life time of network. The simulation result shows that proposed protocol outperforms in comparison with both, energy aware routing protocol and energy unaware routing protocol in high speed and high density environment.
