摘要： A method for proximity detection in a wireless communication network. A node attempts to determine the proximity of the closest neighboring node by transmitting a ranging request. Other nodes respond, and the first node to receive and respond to the request will have the shortest response time and thus will be the closest node. Exact ranges can be determined by applying Time-Of-Arrival (TOA) techniques to node response times. To further avoid collisions, one or more frames of the response messages can be same, making the multiple responses appear as multi-path. The group of responders can be narrowed and individual groups probed in a search pattern until the single nearest node is known or range of the nearest node is known. The ranging node may then use ordinary unicast mechanisms to probe this node, or begin scanning the groups again, or interleave the two mechanisms as desired.

摘要： A method for transmitting groupcast data in a wireless mesh communication network as provided improves security of groupcast data. The method comprises processing, at a supplicant node, authentication handshake data received from an authenticator node, wherein the supplicant node is a next-hop neighbor of the authenticator node away from a root node. The supplicant node then stores a group transient key (GTK) received from the authenticator node. Next, the supplicant node processes authentication handshake data received from a third node, wherein the third node is a next-hop neighbor of the supplicant node away from the root node. The GTK is then transmitted from the supplicant node to the third node. Encrypted groupcast data are then generated at the supplicant node by using the GTK to encrypt groupcast data received from the authenticator node. Finally, the encrypted groupcast data are transmitted from the supplicant node to the third node.

摘要： A method for switching the use of an access point (AP) in a wireless communication network without explicitly updating a proxy address resolution protocol (ARP) cache (200) includes first providing a communication between a network node (111) and a first access point (107) utilizing a first proxy ARP cache. The communication is then switched from the first access point (107) to a second access point (109) utilizing a second proxy ARP cache. In order to reduce messaging traffic in the wireless communications network, any future inquiries regarding the address of the network node (111') continue to be serviced by the first access point (107) and its first proxy ARP cache.

摘要： A method and system for routing data in a wireless network (400) that enables all nodes (106, 402, 404, 406, 408) to find routes to each other even if the nodes are incapable of operating as a router to route packets received from other nodes (106, 402, 404, 406, 408). The meshed nodes (106, 402) which are capable of performing packet routing act as proxy nodes for their associated non-meshed nodes (STA 13 - STA 15) to route packets from their associated non-meshed nodes (STA 13 -STA 15) to destination nodes. Some of the meshed nodes further operate as intelligent access points (106) to provide the non-meshed nodes and other meshed nodes with access to other networks, such as the Internet (402).
