Abstract
Wireless networking is a fertile source of problematical situations with multiple agents, multiple cost criteria, and multiple information patterns. It offers an arena for imaginative solutions for a range of problems.
One example is the power control problem. Choosing the optimal transmit power level of a node in a system as complex as a wireless ad hoc network is an interesting optimization problem. There are several objectives, including maximizing network capacity and minimizing battery usage. Also, the chosen power level affects the functioning of various other network protocols as well. Not only are there theoretical issues, but there are also many issues about harmoniously integrating any power control scheme in the existing network hierarchy.
The COMPOW (for common power) protocol we detail simultaneously increases the network's traffic carrying capacity, provides power aware routes, and reduces the contention for the shared medium. The nodes of the network can run this algorithm in a distributed and asynchronous manner. The software has been implemented in the Linux kernel. To our knowledge it is the first power control protocol to be implemented on a real wireless ad hoc network.
