Abstract
The ad hoc network is a non-infrastructure mobile network that consists of many mobile nodes. Since the nodes have a mobility features in ad hoc network, the ability of communication between the nodes is limited by nodes’ power. The power consumption and bandwidth of each mobile node becomes an important issue and needs to be addressed. The paper discusses the energy efficient routing problem and an Energy-based QoS Routing Protocol in mobile Ad Hoc Network (EQRP). To reduce routing fracture caused by Energy depletion, EQRP selects the nodes that have the largest of the remaining energy in routing discovery and routing maintenance phases. The simulation results show that EQRP has a higher data delivery rate and reduce the number of routing reconstructions.
