移动P2P网络节点具有的移动性,往往导致网络搜索性能变差,同时引起资源搜索成功率的降低以及系统的不稳定性.本文提出一种基于超级节点的资源发现算法(RDBS),它选择性能高且动态性弱的节点作为超级节点,并采用候补超级节点进行快速查询,有效改善了移动P2P网络中资源搜索性能和系统的稳定性.实验结果表明,该算法降低了索引信息的失效率、缩短了查询延迟并且提高了资源搜索的成功率.
The mobility of mobile P2P network nodes often leads to poor performance of network search, which leads to the decrease of success rate of resource search and system instability.In this paper, a resource discovery algorithm based on super node (RDBS) is proposed, which chooses the performance High and weak dynamic node as a super node, and use the candidate super node for quick query, which effectively improves the resource search performance and system stability in mobile P2P network.Experimental results show that the algorithm reduces the failure rate of index information, Shorten the query delay and improve the success rate of resource search.
