| 摘 要： | 跳数对无线网络传输性能的影响以及P2P网络相邻节点物理位置的不相邻导致P2P网络信息检索延迟过大。该文提出基于无线网状网物理特性的超级节点选举机制。根据节点在网状网中的作用和位置特性确立Mesh子域，构建超级节点服务簇，使簇内节点的实际通信跳数较小，控制应用的端到端传输延时。仿真结果表明，该机制能降低约50％的信息检索延迟。

| Abstract: | The number of transferring hops affects wireless network performance, and the neighboring nodes in P2P network are not always physical neighbors. These characteristics bring larger information search delay in P2P network. This paper proposes a super node selection strategy based on physical characteristic of Wireless Mesh Network(WMN). Based on the role and position of Mesh nodes, Mesh domain is ensured, and a super node cluster is formed. This strategy makes nodes in a cluster close with minimal hop count,... |
