Abstract |
Many energy conserving routing protocols have been proposed for Mobile Ad Hoc Network (MANET). Those protocols show that energy consumption in MANET can be reduced by adjusting the transmit power to a minimum level. To determine the minimum transmit power is a challenging issue. A reduced transmit power can cause network partitioning. In order to determine the correct transmit power, mobile node usually uses additional control messages like 'Hello' messages to collect information of its neighbors. That causes a huge overhead which is not desirable. In this paper, we propose a Minimum Energy Dynamic Source Routing (MEDSR) protocol for MANET that ensures connectivity of the network. The Dynamic Source Routing (DSR) protocol has been modified in order to implement MEDSR protocol. Existing control messages of DSR protocol have been modified and used in MEDSR protocol. That is why no additional control message is required. We present an analytical model to show that a considerable portion of energy can be saved by using MEDSR protocol. The MEDSR protocol has been implemented and tested via a Network Simulator (NS-2). The simulation results show that the MEDSR protocol decreases per packet energy consumption. Hence it can deliver more useful data packets compared to DSR protocol. |
