Abstract: As there exists unfairness of channel allocation in wireless mesh networks,the paper proposes a game algorithm based on loss factor which can dynamically optimize weight.In this paper,the game theory is integrated into the channel allocation in wireless mesh networks,the competitive nodes are viewed as participants of the game,it adopts game strategy to compete channel resources.As there exists loss in the process of channel allocation,the loss factor is introduced to dynamically update the weight of game,make game demand demands,and ensuring the fairness of channel allocation.The experimental results show that the improved algorithm improves network throughput,and ensures that the channel allocation is relatively fair.
