为了提高自私网络的路由性能,结合博弈论以及协作虚拟多输入多输出(VMIMO)技术,提出一种基于Group的VMIMO博弈协作路由算法.算法将网络划分成多个Group,分布式地为每个Group选取多个网络结点组成协作传输单元,Group间利用协作传输单元进行VMIMO数据传输.将Group内的协作传输单元选择过程建模为协作节点选择博弈,将Group间VMIMO路由建模为重复路由博弈.为了提高数据转发成功率,提出适用度函数来评估节点信誉,以此为基础,提出基于适用度的重复路由转发算法.仿真实验结果表明本文算法可以有效促进自私节点相互合作,可获得较高的数据转发率,较好地减少数据传输时延以及能量消耗.
In order to improve the routing performance of selfish networks, a group-based VMIMO game cooperative routing algorithm is proposed based on game theory and collaborative virtual multiple input multiple output (VMIMO) technology. The algorithm divides the network into multiple groups, Group selects a plurality of network nodes to form a coordinated transmission unit, and the Group uses the coordinated transmission unit to perform VMIMO data transmission. The selection of coordinated transmission units in a Group is modeled as a cooperative node selection game, the Group VMIMO routing between groups is modeled as a duplicate route Game.In order to improve the success rate of data forwarding, a fitness function is proposed to evaluate the reputation of nodes, and based on this, a new iterative routing algorithm based on fitness is proposed.The simulation results show that the proposed algorithm can effectively promote the cooperation between selfish nodes, High data forwarding rate, to reduce data transmission delay and energy consumption.
