移动自组织网络中基于朋友网络的概率资源查找机制

摘要

Mobile ad hoc networks with high mobility and dynamic,to find resources is a challenge problem in need of solution in the unstable topology network. A distributed probabilistic search mechanism,the mechanism according to the relevant theories of social network has been presented,use of friend relationship and interest similarity as heu-ristic information query message routing,significantly improve the efficiency of searching resources. Simulation re-sults show that,the proposed algorithm has good performance in mobile model based on association.%移动自组织网络具有高移动性和动态性，在这拓扑结构不稳定的网络中查找资源是急需解决的一个挑战问题。该文提出一种分布式概率资源查找机制：根据社会网络的相关理论，利用朋友关系和兴趣相似度作为查询消息的路由启发信息，显著提高了资源查找效率。仿真实验表明：该算法在基于社团的移动模型下具有良好的性能。
