| 摘 要： | 为了提高VoIP节点在DHT网络中定位的可靠性和实时性,根据现有的DHT模型,提出一种新的基于组的节点搜索模型.通过对节点分组和提高节点在路由表中的分布概率以及引入Bootstrap节点,增强节点定位的可靠性,优化节点平均查询开销.仿真中,节点数目由1 024个增加到10 000个的过程中,分别作100 000次查询,可以看出平均查询路径长度没有显著的增加;由于引入Bootstrap节点和节点分组,在网络中节点失败比率增加的情况下,节点查询的成功比率也没有显著下降.

| Abstract: | In order to improve reliability and timeliness for positioning of VoIP node in DHT network,a new group of node-based searching model was proposed according to the DHT model available.By means of nodes grouping,increasing node probability distribution in the routing table,and introducing Bootstrap node,the reliability of node positioning was enhanced and the average cost for node query was optimized.In the simulation process,100 000 queries were performed for 1 024 and 10 000 nodes,respectively,and it was fo... |
