On Tree-Based Routing in Multi-Gateway Association Based Wireless Mesh Networks

Free registration required

Executive Summary

There is an increasing acceptance for Wireless Mesh Networks (WMN) as the potential "Last-mile" access technology running media-rich applications with stringent Quality of Service (QoS) requirements. As WMNs are envisioned to provide high bandwidth broadband services to a large community of users, the Internet Gateway which acts as a central point of attachment for the mesh routers is likely to be a potential bottleneck because of its limited wireless link capacity. The authors propose TBMGA (Tree-Based with Multi-Gateway Association), a novel routing protocol that elegantly balances the load among the different Internet gateways in a WMN.
