    摘要: Systems and methods are provided for improving efficiency and reliability of broadcast transmission in a multi-hop wireless mesh communication network. When an intelligent access point (IAP) receives a broadcast packet (BP), the IAP can determine a list of downlink child mesh nodes (DLCMNs) of the IAP based on route information provided in its routing table. After the IAP knows its DLCMNs, the IAP can determine a first lowest data rate (LDR) between the IAP and each of its DLCMNs, and then re-transmit the BP at the first LDR. The BP is then received by at least one “parent” mesh node, which can then perform similar processing, and can then re-transmit the BP to its DLCMNs. This process repeats until the BP reaches a leaf mesh node. In other words, each mesh node can determine its DLCMNs, determine the LDR between itself and each of its DLCMNs, and can then re-transmit the BP at this LDR.

    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 (106, 402, 404, 406, 408) are non-meshed which are incapable of operating as a router to route packets received from other nodes (106, 402, 404, 406, 408), and for associating and reassociating the non-meshed and meshed nodes with other meshed nodes (106, 402, 404, 406, 408). The non-meshed nodes (STA 13-STA 15) request association with one of the meshed nodes (AP5) which are capable of performing packet routing, to request that the meshed node (AP5) with which the non-meshed node (STA 13) is associating operate as a proxy node to route packets between the associated non-meshed node (STA 13) and other meshed or non-meshed nodes (106, 402, 404, 406, 408). Some of the meshed nodes (106) further operate as intelligent access points (106) to provide the non-meshed nodes (STA 13-STA 15) and other meshed nodes (402) with access to other networks, such as the Internet (402), as well as to effect the association and reassociation of the non-meshed and meshed nodes (106, 402, 404, 406, 408).

    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.
