Efficient transport of IP flows over IEEE802.11 Wireless Mesh Networks

Abstract

Wireless mesh networks (WMNs) based on the IEEE802.11 standards can be used as convenient replacements of wireline networks in the context of home networking to provide users with a variety of services inside the home context for their low cost and easiness of deployment. However, in order to effectively support multimedia as well as ordinary traffic through a WMN infrastructure, traffic control is generally needed as wireless communications, especially in mesh network configurations, can be affected by significant congestion and channel impairments problems. In this work we are focusing on performance assessment and enhancement in IEEE802.11 WMNs. Experimental results are presented using simulation models of IEEE802.11b technology obtained through the open source INET framework of OMNET++ simulator.
