| 摘 要： | 针对喷雾路由自适应能力不强的问题,提出了一种基于种子喷雾的多副本自适应路由协议ASSR.ASSR在源节点计算种子数量和代价预测,利用少量的种子节点进行喷雾,最大程度地减少副本冗余,降低路由代价,由具备最新网络知识的中间转发节点进行喷雾决策,适用于网络环境动态变化的机会网络.仿真实验表明,ASSR在同类协议中具有最低的路由代价,同时具备较强的自适应能力,是一种有效、实用的时延约束机会路由协议.

| Abstract: | According to the shortcoming of traditional spray routing in dynamic opportunistic networks,an adaptive multi-copy routing protocol based on seed spray(ASSR) was proposed in this paper.ASSR calculates the number of seeds and estimates the routing cost in source node,and make spray decisions in relay nodes which have fresher knowledge of the networking conditions than the source.ASSR utilizes only a small quantity of seed nodes to spray message copies for reducing redundant copies.Simulations show that ASSR ... |
