Energy Management in Ad Hoc Mobile Wireless Networks

Energy management issues are very important in the context of ad hoc mobile wireless networks in general and sensor networks in particular. Energy needs to be optimally utilized so that the nodes can perform their functionality satisfactorily. It is known that energy can be managed at various levels. In this paper, we propose energy management at three different levels: component, system, and network levels by suggesting an approach to conserve energy at each of these three levels. We illustrate the approach by considering network traffic with differing QoS requirements. We briefly sketch an approach for energy-centric system design.
