| 摘 要： | 为减轻网络的负担,提出了"局部瓶颈节点"的概念及其分布式检测算法.该类节点具有与瓶颈节点类似的影响,但检测算法更简单可行.特别地,对于布设在带状区域的网络,证明了当布设区域宽度不超过槡3/2倍节点通信半径时,即可根据一跳邻居信息判断一个节点是否是瓶颈节点.结果表明,邻居节点数平均为10时,采用提出的分布式算法,被测节点成为局部瓶颈节点的概率仅为准瓶颈节点的1/4,从而提高了判断的准确性,降低了网络维护成本.

| Abstract: | To reduce network burden,the concept of local-bottleneck node was proposed,and a distributed detection algorithm for local-bottleneck nodes was given.Local-bottleneck nodes have a similar effect on network performance with bottleneck nodes,but their detection is more practicable.Especially,to a network deployed in a belt-type area,it is proved that as long as the width of the area does not exceed 3/2 times of communication radius,one-hop topology information is enough to judge whether a node is a bottleneck... |
