摘要： 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.

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.
