A New TORA-based Energy Aware Routing Protocol in Mobile Ad Hoc Networks

Energy aware routing protocol plays an important role in the performance of mobile ad hoc networks because mobile hosts in such networks are usually battery-operated. In this paper, based on TORA, we present an energy-aware routing protocol E-TORA. E-TORA selects routes according to hop count and residual energy of nodes. The nodes that have more energy have more probability chosen by E-TORA. Simulation results comparing with TORA in NS-2 show that E-TORA can balance effectively energy consumption of each node and increase evidently the lifetime of the network.
