Transmit power control is a prototypical example of a cross-layer design problem. The transmit power level affects signal quality and thus impacts the physical layer, determines the neighboring nodes that can hear the packet and thus the network layer, affects interference which causes congestion and thus affects the transport layer. It is also key to several performance measures such as throughput, delay and energy consumption. The challenge is to determine where in the architecture the power control problem is to be situated, to determine the appropriate power level by studying its impact on several performance issues, to provide a solution which deals properly with the multiple effects of transmit power control, and finally to provide a software architecture for realizing the solution.
