摘要:

提出了以蜂窝自组网与3G核心网络相结合的移动P2P(对等网络)系统的体系结构;详细描述了每一个网络实体的构建方案和功能结构;分析了Peers之间的通信过程。在构建的移动P2P系统中,提出了一种简单有效的索引服务器搜索机制。仿真结果表明,相对于洪泛搜索机制采用索引服务器搜索机制进一步降低了在移动P2P系统上的能量开销,弥补了移动终端的不足。

Abstract:

The architecture on the mobile P2P (peer-to-peer) system which is composed of cellular Ad hoc network and 3G core network is proposed. The construction solution and the functional architecture of each network entity are described in detail, and at the same time, the communication processes between peers are analyzed. A simple and efficient index server searching mechanism is presented in the constructed Mobile P2P system. Simulation shows that, compared with flooding searching mechanism, the energy consumption in mobile P2P system will be improved when in use of index server searching mechanism, to some extent, the deficiency of mobile termination is remedied.

Key words: peer-to-peer, cellular Ad hoc network, distributed hash table, overlay
