An Adaptive Multi-path Routing Algorithm in CogWMN
Zhihua Bao · Telecommunication Engineering · 2010
Paths will alter with the changing of spectrum holes,which has negative effects on transmissions in Cognitive Wireless Mesh Network(CogWMN).An adaptive multi-path algorithm is proposed in this paper.The proposed algorithm adopts multi-agent reinforcement learning model and combines with multi-path scheduling strategy through Q-learning algorithm for updated Q-value route tables.Better route can always be used for nodes to transmit data when route changes.The simulation results show that the algorithm can reduce network latency and improve network performance.
