无线传感器网络节点随机调度算法研究

针对已有的无线传感器网络节点随机调度算法存在的问题,即由于节点是利用产生随机数的方法加入到不同的工作子集,从而导致初始子集中节点分布不均,在概率感知模型下提出了一种基于节点平均度的随机调度算法。该算法利用邻居节点之间的信息传输,使得每个节点的邻居节点尽量均匀分散在不同的子集中。通过随机概率理论分析了概率感知模型下网络覆盖度与节点数之间的关系,解决了新算法的节点配置问题。仿真实验证明了新算法的有效性及分析的正确性。

Research on node random scheduling algorithm in wireless sensor networks

To make the nodes equally distributing in every subset composed of some sensor nodes in the existing random scheduling algorithm of wireless sensor networks(WSN),a random scheduling algorithm based on the average degree of nodes is presented,which is on the basis of a probability sensing model.Taking advantage of information transmission between the neighbor nodes makes the neighbor nodes of every node distribute in different subsets averagely.The relationship between coverage intensity and the number of nodes is analyzed based on the probability sensing model,which resolves the problem of deploying nodes.Simulation verifies the effectiveness and correctness of the proposed algorithm.
