Lifetime aware MPR selection in OLSR for MANET

The energy of mobile nodes is one of the important factors to be considered in MANET. Balanced energy consumption over all nodes in the MANET is difficult and important task to all nodes stay connected in MANET. Lifetime of a mobile node is considered for selecting particular node for routing purposes; here lifetime is calculated based on remaining energy and draining rate of that particular node. Multi Point Relay (MPR) selection provides an efficient routing scheme, Optimized Link State Routing making use of this and implements best proactive protocol in MANET. Considering energy factor in MPR selection yields better results in terms of node lifetime, packet delivery fraction and packet drops.
