An Energy Aware Stable Backup Routing Algorithm in Mobile Ad Hoc Networks

A new scheme called the energy aware stable backup routing algorithm(EASBRA) is presented.EASBRA utilizes the node's geographical information to route and selects the most stable disjoint backup route.EASBRA also introduces a controlled flooding(CF) algorithm.Theoretical analysis showed that compared with traditional flooding(TF),CF can save more energy.And EASBRA reduces the frequency of route discoveries.Simulation results show that compared with AODV and AODV-BR, EASBRA has a higher packet delivery ratio,lower route delay and energy consumption.
