Wireless mesh networks have numerous advantages in terms of connectivity
as well as reliability. Traditionally the nodes in wireless mesh networks are
equipped with single radio, but the limitations are lower throughput and
limited use of the available wireless channel. In order to overcome this, the

recent advances in wireless mesh networks are based on multi-channel multi-
radio approach. Channel assignment is a technique that selects the best

channel for a node or to the entire network just to increase the network
capacity. To maximize the throughput and the capacity of the network,
multiple channels with multiple radios were introduced in these networks. In
the proposed system, algorithms are developed to improve throughput,
minimise delay, reduce average energy consumption and increase the
residual energy for multi radio multi-channel wireless mesh networks. In
literature, the existing channel assignment algorithms fail to consider both
interflow and intra flow interferences. The limitations are inaccurate
bandwidth estimation, throughput degradation under heavy traffic and
unwanted energy consumption during low traffic and increase in delay. In
order to improve the performance of the network distributed optimal
congestion control and channel assignment algorithm (DOCCA) is proposed.
In this algorithm, if congestion is identified, the information is given to
previous node. According to the congestion level, the node adjusts itself to
minimise congestion.
