Fuzzy adaptive power control based on PID algorithm for clusterheads of wireless sensor networks

The distribution of nodes in wireless sensor networks are asymmetrical due to them broadcasted randomly. This situation affects the performance of networks. The power control technology of clusterheads is needed to optimize the framework of networks. Therefore we present an approach of fuzzy adaptive power control about clusterheads based on PID (Proportional, Integral and Differential) algorithm to solve the problem which is difficult to establish an exact mathematic model. The approach is easy to understand and the simulation results showed its validity.
