Minimum-Energy Topology Control Algorithms in Ad Hoc Networks
Abstract
Wireless ad hoc networks can be deployed in many settings such as environment monitoring, disaster relief, and battlefield situations. In these settings, wireless devices such as sensors are often powered by an on-board battery. Many of these networks are expected to function for an extended period of time. In order to accomplish this without a renewable energy source, energy conservation is the key. We consider how to adjust a nodes transmission power to minimize its energy consumption and improve network performance in terms of network lifetime and throughput. We refer to this problem as the topology-control problem. Our focus here is on maximizing the time that the network is able to function, i.e., the network lifetime. We discuss below how network lifetime can be increased, the subtleties of defining it precisely, and the difficulties of achieving optimal network performance in practice.
