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).

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 system and method that creates an abstraction of the physical layer of a wireless communication network (100), in particular, a wireless ad-hoc peer-to-peer communication network (100), and that normalizes the feedback from the physical layer to enable multiple types of nodes (102, 106, 107) in the wireless network to operate using a common wireless routing protocol. This routing protocol uses a link quality metric to determine the best route regardless of how it actually chooses the route or disseminates such link quality information. The generalized routing metric can be derived for any node (102, 106, 107), regardless of its relative performance or its media access control (MAC) technology. The system and method also create a transaction summary that can be used for link adaptation and link quality estimation to determine, for example, future data rates, link quality/routing metrics, and transmit powers.

摘要： A system and method for evaluating at least one communication link between a transmitting node (102, 106, 107) and a receiving node in a communications network (100), such as a wireless ad-hoc communications network (100) in accordance with the 802.11 standard. The system and method perform the operation of assigning respective link quality values to the respective communication links based on a transmit power level (TPL) value at which the respective data packets were transmitted by the transmitting node (102, 106, 107) over the respective links, a received sensitivity (RS) value of the receiving node (102, 106, 107) receiving the data packets, and a receive signal strength indication (RSSI) value provided by the network (100) for each respective link. The system and method can examine a content of a data packet being sent between the two nodes (102, 106, 107) to determine the TPL, and can receive the RSSI value from a physical layer of the communications network (100). Accordingly, the system and method can determine which link that additional data packets are to be sent by the transmitting node (102, 106, 107) to the receiving node (102, 106, 107) via the communication link based on the link quality values. Specifically, the link having the highest link quality value is selected.
