摘要
该文首先结合OSI参考模型,针对无线自组网中节点具有非合作的特性进行了分析,阐述建立激励合作机制的重要性。然后根据网络层上的3种不同的激励合作机制,分类总结其设计的核心思想,并通过具体算法对其有效性进行论证。最后基于博弈理论建立网络模型来描述自组网中节点的行为特征,提出一种激励节点合作的效用函数,并从理论上证明其合理性、有效性。
According to OSI model, the no-cooperation characteristics of nodes and the importance of cooperation mechanism in wireless Ad hoc network are presented in this paper. The key design ideas of three different cooperation mechanisms in the network layer are also analyzed. Based on game theory and network model, the behavior characteristics of nodes are described in details and the utility function to stimulate cooperate is provide at the end of this paper.
