Abstract: Energy efficient routing is an efficient mechanism for minimizing energy cost of data communication in wireless Ad Hoc networks. Normally, routes are revealed taking into consideration the energy consumed for E2E (end-to-end) packet traversal. However, this must not result in discovery of less dependable routes in the network. Energy-efficient routing in Ad Hoc networks is neither full nor well-organized without the concern of residual energy of nodes and reliability of links. Finding consistent routes can improve quality of the service. But, taking into consideration the residual energy of nodes in routing can keep away nodes from being overused and can finally lead to an increase in the operational life span of the network. The main objective of this paper is to propose an E-E-DSR (energy efficient dynamic source routing) protocol in mobile Ad Hoc networks (MANETs) to enhance the network life time. E-E-DSR is used as the base model due to the fact that it is a typical on demand protocol with less bandwidth and energy use. The existing energy efficient routing algorithms namely RMER (reliable minimum energy routing) and RMECR (reliable minimum energy cost routing) are enhanced and implemented in E-DSR.
