摘要
能耗均衡的路由协议对于无线传感器网络至关重要,它能够延长整个网络的生存时间。文中分析了低功耗自适应聚类及其改进协议的优缺点,在其基础上提出了一种基于能量消耗密度的协议。该算法分簇阶段,综合考虑了节点所在区域的密度及簇内节点能耗,平衡各簇中的能耗负载,降低网络中能量消耗不均。仿真结果表明,该算法在能耗均衡性和延长网络生命周期方面比原有算法有了比较大的提高。
Wireless sensor networks require energy-balanced routing protocols to prolong the system lifetime,the Low-Energy Adaptive Clustering Hierarchy and its improved protocols are analyzed,a density of energy consumption-based clustering protocol is proposed. While selecting cluster heads, the protocol can get the density of the area and the nodes'energy consumption of the cluster and keep the network load and energy distribution balanced. The simulations results show that the proposed algorithm is more effective in prolonging the network lifetime and in reducing the energy dissipation compared with the original algorithm.
