摘要
利用目前公认为理论上最好的无线传感器网络集中式覆盖控制算法MCLC(Most-Constrained Least-Constraining),结合DD(Directed Diffusion)和LEACH(Low Energy A-daptive Clustering Hierarchy)路由协议,基于节点最小剩余能量调度覆盖集,观察最小剩余能量不同选取对节点能耗和均衡性以及网络生存期的影响.研究能耗均衡性和网络生存期的关系,提出了一种新的一般性能耗均衡的覆盖集调度的方法.仿真结果表明:所提方法可以有效提高网络生存期,同时为设计覆盖控制算法和覆盖集调度策略提供理论指导.
By employing the most-constrained least-constraining（MCLC） algorithm and directed diffusion（DD） and low energy adaptive clustering hierarchy（LEACH） routing protocol respectively,the performance in terms of nodes energy consumption,the balance of the consumption and the network lifetime of the coverage-scheduling strategies based on the different minimum residual energy of the node among the set was observed.The relation of network lifetime and minimum remaining energy was investigated.A new general approach of coverage-scheduling was proposed.Simulation results show that the new approach can effectively prolong the network lifetime,and meanwhile implies a new approach to design coverage control algorithm and coverage-scheduling policy.
