Reservation and contention reduced channel access method with effective quality of service for wireless mesh networks

The Multichannel assignment in wireless mesh networks is a challenging problem to be solved efficiently by assigning the channels to communicate among the wireless mesh nodes. An algorithm which solves the control channel contention problem and reduces the ripple factor is proposed. The contention problem is reduced by dividing the channel transmission time period and by using the sequential access control factor to make the probability of accessing the channel for all the nodes to be equal. The proposed method, Reservation and Contention Reduced Channel Access (RCR-CA) improves the channel throughput up to 80% with minimum packet loss rate and end-to-end delay. The simulated analysis shows the performance improvement of the proposed method when compared with the existing models.
