A routing protocol based on energy aware in ad hoc networks

The study on the strategy of saving energy and protecting lower energy nodes is attracting more and more attention, because energy resource is one of the most important resources in ad hoc networks where, terminals are always supplied with limited battery. In this study, a novel energy-based local-maintenance protocol EBLM is introduced. In the routing discovery mechanism, relevant algorithm is adopted according to the different levels of node's remaining battery. This hybrid routing protocol considers not only power conservation, but also protecting the nodes with scarce battery. Furthermore, it is effective for load balance on a certain extent. On the other hand, a large reduction of substitute routing discovery time is achieved because of remaining energy awareness and warning strategy in the routing maintenance. Compared with AODV and CMMBCR protocol in various configurations of environment, simulation results showed that this routing protocol prolongs the lifetime and releases the traffic load of the overused nodes effectively. © 2010 Asian Network for Scientific Information.
