Lightweight Tag-Based Forwarding Among Competing Gateways in Wireless Mesh Networks
Wireless Mesh Networks have been traditionally deployed to offer Internet access. Following the general trend of convergence, they must increasingly provide customers with communication services whose quality constraints are heterogeneous. For large scale deployments, access to the Internet is provided by multiple gateways installed at different points in the network. Each gateway may be connected to the Internet with different technologies (ADSL, Ethernet, satellite, HF link) offering several alternatives to get out of the network with heterogeneous and dynamic performances. Routing QoS-constrained flows so that they always benefit from the best quality available is a challenging task.
