| 摘 要： | 由于机会网络环境中两个节点连通时间的限制,消息传输数量往往不能达到理想值。对此,提出一种缓存管理策略ISM(Intelligent Subsection Management),并根据该缓存管理策略提出了一种具有消息副本辐射分发特性的改进路由算法。通过ONE模拟器仿真实验证明,ISM缓存策略在实现网络中消息副本数的公平性的同时兼顾了实效性,改进的路由算法在不同的环境中较Prophet和Epidemic等经典路由也都具有很好的性能。

| Abstract: | The number of transmitted messages can' t reach the level as expected because of the contact duration is limited due to node mobility in an opportunistic network.This paper introduces a new strategy of buffer management named Intelligent Subsection Management (ISM),and we present an advanced routing algorithm in which the distribution of replicates has radiation characteristics according to the ISM.We have proved through the experiment on ONE simulator that the ISM is very good at consideration of the fairn... |
