Hint based Power Efficient Routing Protocol for MANETs

Energy efficient hint based routing protocol (EEHP) in wireless networks is the problem of finding energy efficient shortest active path which also senses the node breakage before occurrence of disconnection and performs a handoff. In the existing Hint Based Routing Protocol (HBP), the nodes discover an active path to the destination exploiting a set of routing meta-information (called hints). The active paths based on hint computation is alone not sufficient for nodes in the ad hoc network for which there may be energy loss during packet transfer leading to disconnection. to avoid path loss a new energy efficient hint based routing approach outperforms the existing HBP protocol by inheriting the node handoff strategy into the HBP protocol which finds the active shortest path based on hint computation followed by route maintenance based on power of the nodes in the active route. The simulation results show that the proposed protocol performs well when a link failure occurrence is identified preventing the route from being broken, leading to energy efficient and better performance in the network.
