Battery and Power Aware Routing in Mobile Ad Hoc Networks

Abstract

Ad hoc wireless networks are power constrained since nodes operate with limited battery. In this paper, it proposes the ad hoc network routing which considers both of power consumption and the amount of the battery remainder. To improve the availability of ad hoc networks, routing which considers both at the same time is needed though power consumption and the amount of the battery remainder have been separately examined in the research so far. We propose BPA-DSR (Battery and Power Aware enhancement to Dynamic Source Routing) which searches for the route by the flooding of two times. The path with large amount of the battery remainder is detected by the first flooding, and the location of the neighboring nodes of the route is computed from the received radio power at the same time. Each link of the route is divided into the power saving link and tuned up by the flooding of the second. Simulation results show that the amount of the battery remainder of the proposed method is better than other method (LP-DSR) which is aware of the power consumption. Power consumption of the proposed method is better than that of DSR though it is a little inferior to LP-DSR which detects the route of minimum power consumption. The number of hops of the detected route is suppressed to about 60% of LP-DSR.
