Traffic-Aware Routing Protocol for Cognitive Network
Yang Xu, Min Sheng, Yan Zhang · 2010
Through sensing and utilizing available network resources, cognitive network can obviously increase network performance. In this paper, a distributed on-demand routing protocol with traffic awareness (TACR) is proposed for cognitive wireless network. This routing protocol establishes the path based on the cognition and reasoning of traffic loads in a network and it also meet quality of service (QoS) requirements by introducing autonomous intelligence-Q-learning. Simulation results show that the TACR routing protocol shortens the average end-to-end delay significantly and also improves the average throughput.
