| 摘 要： | 在灾难场景下能量成为稀缺资源,为在高效转发数据包的同时尽可能减少节点能量消耗,提出基于分组策略的机会网络路由算法.对网络中的节点进行分组,根据角色的特点,采用不同的路由策略.该算法基于泛洪策略,使用p、k、t参数控制泛洪程度.仿真结果表明,在不同的网络规模下,该算法的网络开销均可以接近最优的水平,获得较高的传输成动率,...

| Abstract: | In a disaster scenario,energy resources become scarce.It becomes one of the goals of routing scheme that minimize node energy consumption while forwarding packet efficiently.Routing scheme of opportunistic network based on grouping strategy is proposed.The nodes of network are grouped in accordance with the characteristics.The role of each group is different.Each group uses different routing strategy.The scheme is based on flooding strategy and can control the degree of flooding with p,k,t parameter.Simulation results show that in different network size,the scheme can be closed to the optimal network cost and achieve high delivery rate.It is a suitable routing scheme for disaster scenario. |
