摘要: Methods, systems and data structure for storing and managing information in a wireless network are described wherein fixed resources in the system are stored in a database in a hierarchical directory structure according to the location of each fixed resource. Each level of the directory structure represents a geographical area in which a fixed resource is located. A mobile user submits a query for the location of the nearest fixed resource having certain properties. The system determines the location of the mobile user and then searches the database for the requested fixed resource that is nearest to the mobile user. When the fixed resource is identified, data regarding its location is transmitted to the mobile user. In addition, specific directions as to how to get to the location of the fixed resource from the location of the mobile user may be provided.

摘要: Methods, apparatuses, and systems directed to facilitating roaming and client handoffs in wireless networks. In one implementation, the present invention is directed to a coordination mechanism facilitating handoffs of wireless clients in a wireless network infrastructure. In one implementation, the coordination mechanism minimizes the use of group- or multi-casting to provide a scalable wireless network roaming infrastructure.

摘要: In one embodiment, a wireless access point receives a wireless advertisement frame having a source address field that indicates a reachable node being advertised, a destination address field that indicates a destination to which the reachable node is to be advertised, a transmitter address field that indicates a transmitting node from which the wireless advertisement frame is received, and a receiver address field that indicates the access point. The wireless access point then transmits a reflected wireless advertisement frame having a source address field that indicates the reachable node, a destination address field that indicates the destination, a transmitter address field that indicates the wireless access point, and a receiver address field that indicates both a plurality of receivers the reflected wireless advertisement frame is to be accepted by, and a node that is to be excluded from accepting the reflected wireless advertisement frame.
