无线传感器网络中基于能量的成簇协议

无线传感器网络采用能量有效方式传输数据对于延长传感器网络寿命十分重要。LEACH是一种基于簇的协议,它采用本地簇头随机轮转机制将能量负载均匀分布到网络中的所有传感器节点,簇头节点将收集到数据进行融合后发送给基站。提出一种改进的方案,采用随机成簇算法让网络中传感器节点成簇,成簇的过程考虑传感器节点剩余能量和簇头与非簇头结点之间的距离。通过分析评价和仿真结果,说明新算法比LEACH更能有效利用能量且发送更多的数据。

An Energy-Based Clustering Algorithm in Wireless Sensor Networks

Transporting information in an energy efficient manner is critical to operating the sensor network for a long period of time. LEACH is a clustering-based protocol that utilizes randomized rotation of local cluster to evenly distribute the energy load among the sensors in the network. In this paper,we propose an improved scheme that is a randomized clustering algorithm to organize the sensors in a wireless sensor network into clusters. It forms cluster in according to residual energy of sensors and distance between sensor nodes that differs from randomized rotation of LEACH. Through analytic evaluation and simulation results, we earl see that the new scheme earl use energy more efficient and send more data.
