Incorporating Potential Energy Filed Into Efficient Routing in Wireless Microsensor Networks
Wireless sensor lifespan is one of the most important performance indexes for wireless microsensor networks. Since the radio transmission consumes a lot of energy and working load for sensors are usually non-equalizing, therefore, how to equilibrate working load for sensors can effectively save energy to prolong the sensor and network lifespan. This paper proposed a novel method incorporated potential energy field to predict energy gradient. Data package will be routed to sensor node with higher energy conservation in contrast with their neighbors. Experiment results demonstrated that the proposed approach can precisely estimate sensor energy consumption and dramatically promote the network lifespan.
