GBER:一种基于簇间网关节点的节能路由协议

摘要

In consideration of the problem of hierarchical clustering protocols for wireless sensor networks that cluster heads usually transmit data to the base station directly with the large transmitting distance and the great energy consumption, the paper presents the gateway-based energy etficient routing (GBER) protocol. The GBER protocol can make cluster heads well-distributed, and it can choose appropriate nodes to be gateway nodes to relay data between cluster heads, balancing the energy load of cluster heads, prolonging the network lifetime. The simulations show that the GBER protocol can minimize the energy consumption for communications and balance the energy load among all nodes, making the network lifetime outperform the protocols of LEACH, PEGASIS and iHEED.%针对无线传感器网络现有分簇路由协议簇首节点向SINK节点传输数据时单跳传输距离较长、能量消耗严重的问题,提出了一种高效节能的基于簇间网关节点的路由(GBER)协议.GBER协议能够使簇首节点均匀地分布在网络中,并选择合适的节点成为转发簇间通信数据的网关节点,利用这些网关节点可以分担簇首节点的能量消耗,延长网络生存周期.仿真实验显示,GBER协议的簇首能量消耗很低,网络负载得到有效分担,网络寿命明显优于LEACH协议、PEGASIS协议和iHEED协议.
