无线传感器网络中能量有效分簇路由算法

An Energy Efficient Clustering Routing Algorithm for Wireless Sensor Networks

由于无线传感器节点的电源能量有限,提出了一种能量有效分簇路由算法(EECRA).该算法是基于最小能量的数据转发并运用于簇内路由中,簇头由基站根据节点的剩余能量和簇头之间的距离来选定,为了减小簇头节点的能量开销,簇头之间采用了多跳中继的方式将采集的数据发送到基站.仿真结果证明:该算法与LEACH协议相比,不仅提高了网络寿命,同时节点的能耗均衡性、网络扩展性和可靠性都大大的提高.

In view of the energy limited characteristics of wireless sensor network,an energy efficient clustering routing algorithm（EECRA） in wireless sensor network was proposed.A data delivery based on the minimum energy routing applying in the cluster is proposed.The cluster heads were selected in terms of residual energy of nodes and distance between cluster heads by base station.To reduce power consumption,the cluster heads use multi-hop routing method transmits data to the base station.Simulation results shown that compared with leach protocol,the protocol can lead to the increase of sensor network lifetime.Moreover,the protocol increases the balance of energy dissipation,scalability and reliability of WSNs.
