| 摘 要： | 灾难场景是机会网络重要的应用场景之一,在灾难场景下能量成为稀缺资源,高效转发数据包的同时尽可能减少节点能量消耗成为路由算法追求的目标之一,为此提出了Waitand Spray路由算法,该算法将数据包的转发过程分为Wait和Spray两个阶段,在不同阶段采用不同的路由策略。该算法具有W、K、M参数,恰当的参数设置可控制Spray阶段的泛洪程度,大幅提高算法性能。仿真结果表明,该算法可在获得高传输成功率的同时,大幅降低路由开销,是一种适合在能量稀缺场景下应用的路由算法。

| Abstract: | Disaster scenario is one of the important scenarios of opportunistic network.In a disaster scenario,energy resources become scarce.It becomes one of the goals of routing algorithm that minimize node energy consumption while forwarding packet efficiently.Wait and Spray routing algorithm is proposed.The packet forwarding process is divided into two stages:Wait and Spray.The routing strategy of each stage is different.The algorithm has W,K,M parameters.Appropriate sets of parameters can control the flooding at... |
