摘要
无线传感器网络内部能耗不均衡容易导致节点提早死亡,为此大量的能耗均衡路由协议被提出。然而这类方法主要针对环状无线传感器网络。带状无线传感器网络呈长条形分布,传统的能耗均衡路由协议无法发挥节能和能耗均衡的作用。提出一种基于移动Sink的带状无线传感器网络数据汇聚方法,首先基于节点能耗模型计算簇内节点的平均能耗,然后利用节点平均能耗求取Sink节点的最佳移动速度,最后簇首节点根据它与Sink节点的距离动态调整数据传输范围,从而实现对带状传感器网络的数据汇聚。实验结果表明该方法具有较好的节能性和能耗均衡性,能够有效延长网络的生存周期。
Due to the imbalance of energy consumption in wireless sensor networks(WSN),it is easy to lead to the early death of nodes.Therefore,a large number of energy balanced routing protocols have been proposed.However,these protocols mainly aim at ring-shaped wireless sensor networks.Band wireless sensor network is distributed in a long strip,and traditional energy balance routing protocols can’t play the role of energy saving and energy balancing.A data aggregation method is proposed based on mobile Sink for banded WSN.Firstly,the average energy consumption of the nodes in the cluster is calculated based on the energy consumption model of nodes.Then,the optimal moving speed of Sink node is calculated by the average energy consumption of nodes.Finally,the cluster head node dynamically adjusts the data transmission range according to its distance to Sink node,so as to realize the data aggregation of banded sensor network.Experimental results show that this method has better energy conservation and energy consumption balance,and can effectively extend the network life cycle.
