A New Techniques for Power Aware Routing Algorithm for Mobile Ad Hoc Networks

An Ad Hoc network is an infrastructure less wireless network consisting of mobile moving nodes. In a network each mobile node act as a router as well as packet forwarder. Nodes in a Mobile Ad hoc Network (MANET) have limited battery power. Power consumption of network interfaces can be significant. In a MANET, if a mobile node continuously transmitting the data packets, more battery power consumed by that node, obviously that node energy level is insufficient for data packet transmission and becomes critical node or dead node and result is connection failure in network. When a distance is increased between mobile nodes in same MANET, those mobile nodes consumed more power for the data packet transmission. The proposed work minimises the energy consumption per packet and maximises the network lifetime. The design objective of modifying DSR is to select energy efficient paths. The main features of modified DSR are: (i) minimise energy consumed per packet (ii) maximise network lifetime for network and (iii) minimise maximum node cost. However, some intermediate nodes might act selfish and drop the packets for other nodes in order to save their own battery power. The proposed algorithm can find selfish nodes and deal with them by using a modified DSR protocol, which we call as an efficient DSR (EDSR). The simulation results show an increase in the packet delivery ratio in the network. The average node lifetime of proposed EDSR model is 45–60% longer than that of DSR model.
