Power Consumption Analysis in Mobile Ad Hoc Networks

The central challenge in the design of ad-hoc wireless networks is the development of a dynamic routing protocol that efficiently finds routes between mobile nodes. Several network routing protocols such as Dynamic Source Routing (DSR), Ad Hoc On-demand Distance Vec-tor (AODV) and Destination Sequence Distance Vector (DSDV) have been proposed to facilitate communication in a dynamically changing network area. Mobile Ad hoc Network (MANET) is faced with various challenges such as resource consumption during network routing operation. This paper present results from detailed power measurement studies of MANETs with emphasis on power consumption with different antenna designs. Computational simulation is used to analyse the power consumption in MANET on two platforms i.e network configured with directional and omnidirectional antenna. The simulation results show that networks configured with directional antennas save 68% of the power as compared to networks configured with omni-directional antennas. While 99% packet delivery ratio were achieved with networks configured with directional antenna as compared to network with omnidirectional antenna.
