一种基于簇的无线传感器网络能量有效路由协议

Routing protocol based on clustering and energy-efficient in wireless sensor networks

由于传感器节点的电源能量、通信能力和计算能力都十分有限。为了提高无线传感器网络(W SNs)的生命周期,提出了一种基于簇的高效节能的传感器网络路由协议。该协议提出了基于最小成本路径的数据转发法并运用于簇内路由中。同时,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。仿真证明:该协议与LEACH协议相比,其网络寿命提高了500%,此外,该协议还提高了传感器节点的能耗均衡性、网络扩展性和可靠性。

Because of the limited energy, communication and computation capability of sensor nodes, a routing protocol based on clustering in wireless sensor networks（WSNs） is proposed to increase the energy efficiency and prolong lifetime of the WSNs. A data delivery based on the minimum cost routing which apply in the cluster is proposed. In addition,it assumes that the inter-cluster communication data in a multi-hop manner is sent to the designated node, it then sends the gathered data by the whole network to the base station. Simulation results shown that compared with leach protocol, the protocol can lead to the increase of sensor network lifetime by 500 %. Moreover,the protocol increase the balance of energy dissipation,scalability and reliability of WSNs.
