基于双响应模式的WSN节能控制算法

An Energy Conservation Algorithm Based on Dual-response mode for Wireless Sensor Networks(ECAD)

为使无线传感器网络(WSN)在应用中能够兼具能效高与实时性的双重优势,依据图论中根树的概念,参考定向扩散协议中梯度的思想,引入软硬阈值与休眠机制,提出一种基于双重响应模式的WSN节能控制算法(ECAD);通过理论分析和对算法的模拟仿真结果表明,该算法在达到实时性目标的同时,使网络生命周期内簇头轮换次数明显减少,这样更多能量就能被用于对有效数据的采集和传输,从而可延长网络总体寿命。

In order to have an advantage of both efficiency and real-time for Wireless Sensor Networks（WSN） in application, an Energy Conservation Algorithm based on Dual-response mode for WSN（ECAD） is proposed according to the concept of rooted tree in graph theory, taking the gradient thought in directed diffusion protocol into reference, and making hard-threshold, soft-threshold and sleep-mechanisms adopted. It is proved by theoretical analysis and computer simulation for the algorithm that it could reduce the number of clustering in the whole lifecycle, while being provided with real-time feature. So that there will be more proportion of the total energy applied for collecting and transmitting useful data. And that it is beneficial to prolong the lifetime of WSN.
