Abstract

An internetworking node for providing internetworking services for mobile wireless nodes is disclosed. Each mobile wireless node is registered withat the most one internetworking node. Each mobile wireless node emits a topologybroadcast identifying itself and other nodes it has heard. Each internetworking node uses these topology broadcasts to construct a table tracking each mobile node within its range, whether that mobile node is registered to that internetworking node and also a list of which other nodes that mobile wireless node can hear. The internetworking node determines which of these wireless nodes it will register. The internetworking node will then act for all wireless nodes registered to it in relaying messages between wireless nodes or between a wired LAN and the wireless nodes.
