不同合作度下机会网络典型路由算法健壮性分析*

机会网络路由算法在不同合作度下的健壮性是一个重要的但未被充分研究的问题，分析了机会网络中可能存在的节点间不合作的情况，定义了三种适用于不同场景的节点合作度，设计了评价方法及指标体系，通过对真实城市场景中带有智能蓝牙设备行人移动行为的仿真，定量分析了不同节点合作度下Direct Delivery、Epidemic、Spray and Wait、Prophet和MaxProp 五种典型路由算法的健壮性。结果表明Spray and Wait和MaxProp算法健壮性较差，Prophet 和Epidemic算法较

Robustness analysis of opportunistic network routing algorithm with different degree of node cooperation

Robustness of opportunistic network routing algorithms with different degree of node cooperation is an important issue but not yet thorough researches.This paper analyzed failures to cooperation of the nodes in opportunistic network briefly. It also proposed three degrees of node cooperation for different situations and designed the evaluation criteria. Then the method simulated the actions of the pedestrians with the intelligent bluetooth devices in the scene of the real city. On these bases, it analyzed the robustness of these five algorithms which were Direct Delivery, Epidemic, Spray and Wait, Prophet and MaxProp. The performance on the obtained experimental results demonstrate that Spray and Wait and MaxProp have poor robustness, and Direct Delivery is best.
