Amit Saha, Throughput Improvement in Wireless Mesh Networks

In a wireless mesh network, nodes known as transit access points (TAPs) cooperatively forward traffic from users that may be multiple wireless hops apart. A limited number of TAPs also have a connection directly to the Internet, serving as gateway nodes that provide Internet connectivity to the entire mesh network.

I present a number of noel traffic-aware routing metrics that take into account existing user traffic flows in the network. Previous routing metrics have been traffic-unaware, often causing routes with poor throughput to be selected when other better routes are available. These new traffic-aware metrics use information captured through measurements at the medium access control (MAC) layer, which are then exposed to the routing layer. I compare these traffic-aware metrics with existing traffic-unaware metrics under different network scenarios.
