Dynamic Power Management in Multi Path Mobile ADHOC Networks
Udai Shankar · 2012
A Mobile Ad-Hoc Network (MANET) is a collection of mobile nodes (such as laptops, PDAs) forming as arbitrary networks without the support of any fixed infrastructure such as base station or access point. There is no fixed topology due to the node mobility, which results in interference, multipath propagation and path loss. Mobile nodes are constraints to battery power, computation capacity, bandwidth, and wireless channel leading to number of challenges while design routing procedures. In a mobile ad hoc network, nodes are often powered by batteries. The power level of a battery is finite and limits the lifetime of a node. Every message sent and every computation performed drains the battery. In this paper we present a case for using new power-aware metrics for determining routes in wireless mobile ad hoc networks. We present different metrics based on battery power consumption at nodes. We show that using these metrics in shortest-cost routing algorithms reduces the cost/packet of routing packets by significant percentage.
