Transmission power management in ad hoc networks: issues and advantages

Power management is a very important aspect of ad-hoc networks. With power management capacity, throughput and battery lifetime could be increased, and latency could be reduced. But all of these advantages may be hindered depending on the power management employed and depending on the network configuration. In this paper, issues and advantages involved in the design of power control and management schemes are discussed. We also present a novel approach to power management by utilizing modern control theory to achieve the low-level power control. Simulation has shown that the new approach provides a more accurate and faster power control, than traditional power control.
