Energy is very important parameter during the creation of a Wireless Sensor Network (WSN) infrastructure, and to support long lifetimes, energy-efficient operation is a key technique. Wireless Sensor Networks (WSNs) are known to be highly energy-constrained and each network's lifetime has a strong dependence on the node's battery capacity. As such, the network lifetime has been a critical concern in WSN research. While numerous energy-efficient protocols have been proposed to prolong the network lifetime. Energy-efficient sensor state planning consists finding an optimal assignment of states to sensors in order to maximize network lifetime.
