A light-weight internet gateway discovery scheme for infrastructure mesh networks

Infrastructure mesh networks offer a high-capacity wireless backhaul network through which client devices, such as PDAs, can connect to one another or with the Internet. In dynamically deployed mesh networks the routers within the mesh network may be unaware of existing Internet gateways and need to discover them on demand. In this paper we present a lightweight gateway discovery and traffic forwarding approach for discovering the presence of these Internet gateways and managing communication with them. A comparison of our work with existing approaches shows that our method is superior in terms of latency and per packet overhead.
