| 摘 要： | 节点随机调度算法,是一种研究网络局部覆盖的重要方法,它无需知道节点位置信息、简单易用并有较高的实用价值。但是目前对该算法的研究成果均是基于布尔感知模型设计。布尔感知模型尽管简单,但不能真实地反映节点的感知能力。文中首次在概率感知模型下,分析了随机调度算法中网络覆盖度与节点数之间的关系,给出了节点数的下界值,并通过仿真验证了分析的正确性。

| Abstract: | The Random Scheduling Algorithm of WSN(Wireless Sensor Networks)is an important scheduling algorithm for local coverage of networks.It does not need geographic information and is therefore easy to operate and of great practical value.However,the present researches on the existing Random Scheduling Algorithm are all based on the Boolean sensing model,which is simple but can't reflect the real sensing ability of nodes.This paper analyzes the relationship between coverage intensity and the number of nodes and ... |
