无线mesh网络中可信协同信道资源分配策略

为了有效提升无线mesh网络信道资源的利用率和网络服务质量,提出基于可信协同的信道资源分配策略.针对节点自适应特点,引入博弈理论、建立节点的信誉机制以实现节点可信协同并优化信道分配结果.仿真实验分别对节点服务等级、网络收益结果作相应评价.实验结果发现节点服务等级对节点网络收益有直接影响,当协同服务等级达到3时,网络收益状况最佳,此时节点跳数与服务等级呈协同关系;对比经典协同算法,在相同网络拓扑环境下,可信协同信道资源分配策略分别是UACRR算法、DMP-MBA算法的1.04倍、1.069倍,明显占优.

Dependable-cooperative channel resource allocation scheme in wireless mesh network

For improving utilization of channel resources and service quality effectively in wireless mesh network,a dependable-cooperative channel resource allocation scheme was proposed.According to the adaptive features of mesh node,engaging game theory and establishing reputation mechanism to achieve dependable-cooperative of nodes,and channel resource allocation result was utilized.The comparison of this experiment proves the situation of service level and network utility of cooperative service.The result of it shows that networks benefit will be optimal when the cooperative service level is 3 and node hops synergies with the service level.Comparing with classic synergetic algorithm,with the same context of network topology,dependable-cooperative channel allocation strategy is clearly dominated with 1.04 on UACRR and 1.069.
