DEVELOPMENT OF MAXIMUM BANDWIDTH CAPTURING PATH WEIGHT PROTOCOL TO RECOVER BANDWIDTH CONSTRAINED ROUTING PROBLEM

A fundamental?issue?in supporting quality-of-service is the problem of identifying the maximum available bandwidth path WMNs. Since Wireless Mesh Network (WMN) has become an important edge network to provide Internet access to remote areas and wireless connections in a metropolitan scale. Due to interference among links, bandwidth, a well-known bottleneck metric in wired networks, is neither concave nor additive in wireless networks. A new path weight which captures the available path bandwidth information is proposed. Hop-by-hop routing protocol based on the new path weight satisfies the consistency and loop-freeness requirements. The consistency property guarantees that each node makes a proper packet forwarding decision, so that a data packet does traverse over the intended path. The simulation study shows that the proposed path weight outperforms existing path metrics in identifying high-throughput paths.
