碩士 === 元智大學 === 資訊工程學系 === 95 === Wireless sensor networks are composed of one or more hubs and lots of sensors. A sensor has capability of sensing, wireless communication and data processing. They collect the information about the status or changes of sensed objects and environment and then send it to the hubs for integration. Since these sensors are equipped with batteries, their activities are restricted by the limited power. Therefore, how to extend the network lifetime is an important issue. In EAR[1], it utilizes both the shortest path and next hop energy for path selection. Nevertheless, the next hop energy is not suitable to represent the path energy. In this paper, we propose a routing protocol which uses the water flow idea and allocates the loading based on the lowest energy in paths. From the simulation result, it shows that our approach could extend the network lifetime efficiently.
