Power conservation is a major issue in wireless sensor networks, as most of the nodes are battery powered. Power control is not related to any particular layer, since the authors can apply power conservation methods in all layers. But most of the power control mechanisms are working in MAC layer. Here, they analysis a Power Control MAC protocol for wireless sensor network with overall power consumption and improvement the throughput of the network. Thus, their protocol includes two phases; in the first phase they reduce the power consumption and in the second phase they improve the aggregate throughput of the network. Their work is based on the IEEE 802.11 MAC protocol.
