Hop count based energy saving dynamic source routing protocol for ad hoc network

Abstract

Energy conservation has become one of the challenging issues for increasing the life time of Mobile Ad hoc Network (MANET). Several energy saving protocols have been proposed to maximize the life span and one such protocol is Energy Saving Dynamic Source Routing (ESDSR) protocol. ESDSR focuses only on energy and does not consider delay caused due to increase in hop count. This paper Hop Count based ESDSR (HCESDSR) protocol proposes a novel approach to maximize the life span of MANET and to reduce the energy consumption. This reduces the delay caused in ESDSR by considering energy as well as hop count. The number of dead node formation is less in proposed work and hence increases the life of network. The route selection is based on number of hops and energy level of that route. The protocol is simulated using network simulator NS2. The simulation results show that this approach attains energy efficiency of ESDSR and overcomes the limitations of ESDSR. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
