Abstract
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.

Congestion control routing using optimal channel assignment mechanism in wireless mesh network

TL;DR: A mechanism to avoid channel switching delay caused by CA procedure, using Dijkstra's algorithm, is proposed, which keeps a record of congested channels in the form of a table and uses this information to assign a non-negative weighted score to the pair of nodes for efficient routing with less switching delay and overheads.
