| 摘 要： | 连通性与稀疏性是无线传感器网络的重要拓扑属性,针对良好的网络拓扑既要保证连通又要适当降低连边密度的问题,首先分析了网络连通概率的相变特性,发现存在临界传输半径,在此临界值周围网络连通概率会发生0-1相变.其次,在网络以较小的传输半径保持连通的情况下,以度和介数作为衡量节点重要性的指标,提出了稀疏网络拓扑优化算法,通过适...

| Abstract: | Connectivity and sparseness are important topological property of wireless sensor network.A good network topology can guarantee both connectivity and lowered density of connected-edges simultaneously.Aiming at this problem,firstly,the property of phase transition for connectivity probability of wireless sensor networks is analyzed.The results show that there exists a critical communication radius on which probability of connectivity sharply changes from 0 to 1.The shortest communication radius which ensurin... |
