Transmission power has a major impact on link and communication reliability and network lifetime in wireless sensor networks. The authors study power control in a multi-hop wireless sensor network where nodes' communication interferes with each other. This paper is to determine each node's transmission power level that will reduce the communication interference and keep energy consumption to a minimum. They propose a potential game approach to obtain the unique equilibrium of the network transmission power allocation. The unique equilibrium is located in a continuous domain. However, radio transceivers accept only discrete values for transmission power level setting.
