Wireless sensor networks (WSNs) consists ofunattended sensors with limited storage, energy (battery power)and computation and communication capabilities. So, energy efficient mechanism for wireless communication on each sensor node is so crucial for wireless sensor networks. Wireless industrial sensor networks are wireless sensor networks which have been adapted to industrial applications. Most techniques for wireless sensor networks can be applied to wireless industrial sensor networks. A wireless sensor node is often powered by battery which is not easily replaced, so researching how to use itslimited energy effectively is the meaningful for wireless sensor networks(WSNs). Energy routing protocol is suitable for industrial applications due to its capability of energy efficient,real-time,reliable comm.& energy efficient algorithm is provided which based on power control
