基于能量平衡的WSN簇头选择机制

通过对已有的基于簇的自组织路由算法和簇头选择机制的分析比较,发现经典LEACH算法在选取簇头节点时具有不合理性,提出了一种基于PSO模型的簇头选择机制。以网络总体能量消耗最小为原则,综合考虑节点剩余能量和网络当前平均能量,较好地平衡了无线传感器网络中的能量负载,延长了网络的生命周期。

Cluster Head Selection Mechanism for WSN Based on Energy Balance

Through analysis and comparison of the existing self-organizing cluster-based routing algorithms and the cluster head selection mechanism, this paper finds that classical LEACH algorithm is unreasonable in the election of cluster head nodes, and proposes a PSO-based cluster head selection mechanism. Following the principle of the overall network energy minimization,and considering both of the residual energy of each node and the average energy of current network, the improved algorithm is better able to balance the energy burden in wireless sensor networks, and extend the network life cycle.
