一种适用于移动Ad hoc网络的无线P2P应用架构

A Novel Wireless Peer-to-Peer Application Architecture for Mobile Ad Hoc Networks

移动AdHoc网络和P2P技术近年来迅速发展,各种新的应用层出不穷,向广大用户提供了多种新兴服务。相关研究表明,在现有的移动AdHoc网络中直接应用P2P技术,会影响整个网络的性能。本文采用跨层思想,提出新型的无线P2P应用架构,包括了资源搜索和文件传输的整个过程,实现了基于存储内容的分布式网络资源管理。该架构设计了适用于移动AdHoc网络的P2P拓扑结构,定义了各节点内部的模块功能和算法流程。本文还引入用户偏好和信用记录的机制,更好的满足了无线自组织网络中各种P2P应用的不同QoS需求以及每位用户的需求。

Wireless Ad Hoc network and P2P technologies develop rapidly in recent years, and provide lots of novel applications and services for users. Related research results reveal that the direct use of P2P in present wireless Ad Hoc network will affect the whole system performance. We propose a new wireless P2P application architecture based on cross-layers scheme, including complete procedure of resource discovery and file transmission, realizing actual distributed network resource management based on content. It designs P2P topology suitable for wireless Ad Hoc network as well as defines function modules and flow procedures. The introduction of user preference and credit record scheme fulfills different QoS requirements of different P2P applications and various users in wireless Ad Hoc networks.
