Abstract
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 the proposed research, algorithms are developed to improve throughput, minimise delay, reduce average energy consumption and increase the residual energy for multi radio multichannel wireless mesh networks. Interference is the main factor which directly impacts the network capacity. In literature, the existing channel assignment algorithms fail to consider both interflow and intra flow interfaces. The limitations are inaccurate bandwidth estimation, throughput degradation under heavy traffic and unwanted energy consumption during low traffic and increase in delay. In the present research, a protocol called Priority Based Interference Aware Channel Assignment with Bandwidth Reservation is proposed to estimate the required bandwidth accurately. All the nodes calculate its bandwidth availability for its links. The nodes check the available links that can be used for the requirements of the incoming flow in the admission control process. Priority is given to each link based on the interference information. If any link is not able to meet the flow requirements while data transmission, it will be reported to the sender node to stop the transmission. Though interference is minimized in this algorithm, the performance is degraded due to congestion.
