Wireless sensor networks have received academia research attention at present. A typically task in a wireless sensor network is that every sensor node senses its local environment and, upon request, sends the data of interest back to the sink node. The energy-constrain sensors in wireless sensor networks operate on limited batteries, so it is a very important issue to use energy efficiently and reduce power consumption. Most recent routing protocols tend to find the minimum energy cost path to lower energy usage for all routing paths, thus, they may lead to some of the nodes deplete their energy quickly.
