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).

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 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 to control congestion in a multihopping wireless communication network (100). The system and method distribute the congestion information back to the ingress points (106) and traffic source nodes (102, 106, 107) in the network (100) through the actual route of the data flow that contributes to the congestion. The system and method therefore avoid bottleneck points (102-5) in the network (100) to reduce congestion. The system and method can be used for packet-based, route-based or flow-based traffic shaping in a multihop wireless network (100) employing different media access control (MAC) and routing layer protocols. Moreover, the system and method is capable of distributing congestion and service differentiation information between different interfaces in the network (100).

摘要： A system and method for providing a traffic control scheme for QoS provision and congestion control across multiple interfaces of wireless nodes (102, 106 and 107), such as wireless access points (107 and 106), communicating in a wireless multihopping communication network (100). The nodes (102, 106 and 107) can include multiple transceivers. The system and method detects bottleneck interfaces in these nodes (102, 106, 107) to control the traffic along the path of the corresponding traffic flow. Different measurements and cross-layer feedback are used to differentiate the cause of the congestion, such as wireless link quality degradation due to fading or degradation due to congestion in a shared medium. The nodes (102, 106, 107) inform each other on the status of their congestion level. High and low level signaling and interruption mechanisms are used to control the interfaces of the congested node (102, 106 or 107) to adjust traffic flow and alleviate the congestion.

摘要： A system and method for a media access control (MAC) scheduling algorithm having a distributed, self-coordinating approach to provide use fairness and service differentiation in an ad hoc network by using control RTS/CTS messages carrying node status information. A local scheduling algorithm uses the overheard RTS/CTS information with attributes specifying nodes' status to maximize the awareness of the neighborhood status for a multi-channel system where data and ACK messages are transmitted through different data channels. If the system uses a single channel, the corresponding information may be carried by using DATA or ACK messages. The algorithm measures the offered load, carried load, and backlogged load in the neighborhood to adjust the channel access timer to provide use fairness among different nodes, different links, and different streams. The algorithm can further both calculate the priority level based on the node queue status, and calculate the priority level based on the neighbor status, to break the contention tiers and enable the service differentiation.

摘要： A method for managing secure routing keys (200) for on-demand routing protocols used in a wireless mesh network includes sending an secure routing key from a key distribution node to an access node (201). A temporary communications route which is time and usage limited is initiated (203) between a wireless device and an internet access point when the wireless device initially joins the network. A secure routing key is sent (205) from the internet access point connected with the key distribution center to the wireless device. Thereafter, the secure routing operation can be started to establish secure routes among all wireless devices which have obtained the same secure routing key in the same manner. Thus, the invention defines a simple and efficient key management technique using initial key establishment and re-keying through dynamically updated key vectors.

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.
