To enable multimedia broadcasting services in mesh networks, it is critical to optimize the broadcast traffic load. Traditionally, users associate with Access Points (APs) with the strongest signal strength. The authors explore the concept of dual-association, where the AP for unicast traffic and the AP for broadcast traffic are independently chosen by exploiting overlapping coverages that are typical in mesh networks. The goal of their proposed solution is to optimize the overall network load by exploiting the flexibility provided by independent selection of unicast and broadcast APs. They propose a novel cost metric based on ETT (Expected Transmission Time) and the number of nodes in range of the APs that are advertised in the beacons from the APs.
