Traffic Rank Based QoS Routing in Wireless Mesh Network

摘要

Wireless Mesh Network (WMN) is a network to provide Internet access to remote areas. As part of the Internet, WMN has to support multimedia applications to all its users. It is essential to provide efficient QualityofService (QoS) support to the networks. Searching the better quality path with the maximum available utilized bandwidth is one of the fundamental issues for supporting QoS in the WMN. Real time applications such as type of media access like video, audio, mail services varies from one node internet access to another node internet access. A small variation of the efficient QualityofService (QoS) metrics like jitter, delay, and throughput, has significant impact on the bandwidth and link capacity demands of the node. In this paper we present a computing of better rank based path, which captures the available path utilized bandwidth information is proposed. This paper also show, that the efficient routing protocol based on the new rank based path which provides the consistency. The consistency property guarantees that each node in the traffic makes an appropriate packet forwarding decision, based on the assigned ranks, so that a data packet does travels through the exact path. Once the current path fails the rerouting of the packet is supported. The OMNeT++ 4.2.2 simulation experiments also show that the proposed rank based path gives highthroughput paths.
