A Hop-adaptive Routing Algorithm for Wireless Sensor and Actor Networks
Dou Wen-hua · Dianzi xuebao · 2010
Wireless sensor and actor networks(WSANs) are composed of a large number of sensors and a small number of(mobile) resource-rich actors.Sensors gather information about the physical phenomenon,while actors take decisions and then perform appropriate actions upon the environment.The paper analyzes the model of energy consumption,and solves the optimal number of hops when the total energy consumption in a path is minimal under the ideal condition.After that,a hop-adaptive routing algorithm(HAR) is proposed to realize the balance between the real-time requirement of data collection and the total energy consumption of the network.The extensive simulations show that,HAR algorithm is advantage to HBMECT algorithm with the balance of real-time and energy-consuming,and it adapts to the case of mobile actor.
