基于博弈的DTMSN路由选择和信任决策

Game-based Routing Selection and Trust Decisions for DTMSN

针对延时容忍移动传感器网络中节点自私性检测存在未考虑节点由于自身问题不能转发数据而引起信誉值计算不精确和重传数据造成能量浪费的问题,通过引入剩余能量和能否进行数据转发的两个概念,结合相应的惩罚机制,进一步提高了延时容忍移动传感器网络中节点自私性检查的准确度,同时可以延长网络的生存时间。对于现有延时容忍移动传感器网络中缺乏相应的激励机制,引入博弈的思想,通过理论证明,在条件允许的情况下节点会选择合作的行为,从而增加节点主动转发数据的积极性,提高网络的投递成功率,减少网络开销。

To deal with the inaccurate claculation problem and energy waste caused by the node can not forward the data for the reason of itself,which has not been thought by the previous detection of selfishness for delay tolerant mobile sensor networks,this paper introduced the concepts of the remaining energy and the flag that can or not forward the packages to improve the previous.Also the mechanism of punishment is used to avoid the sham information of energy and flag.Both of all make the value of credit better.The thought of game is also used in this paper to stimulate the cooperation in the good condition,the theoretical also say the same.For the reason of game,the node can cooperate with each other more,increasing the initiative of forwarding date,which can improve the success rate and reduce the overhead of network.
