摘要
当无线传感器网络中的多个sink集中移动时,由于现有的路由协议需要每个sink向源节点更新位置,从而造成路由载荷过高的问题。为了解决这种问题,文章提出了一种基于移动sink群组的数据传输协议——群组组头位置更新方式,达到减少路由开销、节省网络能耗的目的。实验证明,本协议在保证数据有效传输的同时,降低了网络能量的损耗,延长了网络寿命。
In wireless sensor network（WSN）, when a number of sinks staying closely move together, the existing routing protocols require every sink to update its location to the source. As a result, the routing overhead becomes too high. To solve this problem, a data transmission protocol based on mobile sink group, i.e. the leader of group location updating method, is proposed to reduce the routing overhead and economize the energy consumption of the network. The simulation results indicate that the proposed protocol not only guarantees the success delivery ratio of data packets, but also reduces the energy consumption of the network and prolongs the lifetime of the network.
