An Energy-Efficient Ring Search Routing Protocol Using Energy Parameters in Path Selection

Abstract

Routing protocol is very important in Ad hoc network. From the EERS [3] protocol, we have improved AODV protocol to consume energy more efficiently. However, this method depends only on hop count number, but not energy. This leads to central nodes’ exhaustion of energy and influences the entire network lifetime. In this paper, we propose two new protocols from EERS, called Avoid Bad Route (ABR) and Routing Dual Criterion (RDC). In both protocols, we base on energy criteria. Therefore, the lifetime as well as the throughput of the whole network are improved.
