摘要： Graphical display data representing an image for display is packetized for wireless transmission. At least one command for displaying the image from the data is within the packet. The command is used to display the image, as represented by the packetized data, in related configurations to create an animated display or at predetermined times or intervals to make the image appear spontaneously or be removed after a predetermined period of time for later display or are erased. Transmission of the packetized data occurs when the receiving devise is idle. The transmission of the packets may be interrupted by a present need to establish a communications channel with the receiving device, for example for voice communication or for transmission of hyperlinked data. A handshake protocol is used to assure the parts of the packetized data are successfully downloaded.

摘要： A system and method for providing the ability to selectively share data in a network routing device with an associated host. The system and method employs a hardware firewall in the routing device which restricts the host such that it can only access areas in shared memory which contains data destined for the host. The routing device CPU notifies the host of pending data and the location of that data in the shared memory. The hardware firewall is also notified of the location in shared memory which the host may access. When the host attempts to read the data, the firewall ensures that only the stated memory area or areas are accessed by the host. Once the data has been read by the host, the firewall is notified to cancel the host's ability to access the shared memory until such time as a new packet destined for the host arrives in the routing device.

摘要： A system and method for providing a mechanism for trans-medium address resolution on a network with at least one highly disconnected medium having multiple access points to other media. The system and method provides a “unique” media access control (MAC) address in address resolution protocol (ARP) for mobile nodes in an ad-hoc network, correctly identifying the optimum intelligent access point (IAP) for node communication where the optimum IAP changes more rapidly than traditional address updating may be able to accommodate. Medium layer routing protocols recognize medium frames addressed with this unique MAC address should be routed to the currently associated IAP, whichever IAP that might be at the moment the frame is sent.

摘要： A method and device for providing an alternative backhaul portal at a mesh access point in a mesh network as provided enables improved backhaul services. The method includes processing a registration of the mesh access point as an alternative backhaul portal in the mesh network. It is then determined that additional backhaul capacity is required in the mesh network. Next, the mesh access point is activated as an alternative backhaul portal in the mesh network in response to determining that additional backhaul capacity is required. Mesh network data are then routed through the alternative backhaul portal at the mesh access point until it is determined that additional backhaul capacity is no longer required. The mesh access point is then deactivated as an alternative backhaul portal in the mesh network.

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 communication device (102) has a serving and neighbor list (202) and a bandmap (204, 206). Upon losing communication service (402) the device begins alternately scanning the serving and neighbor list (SNL) and subsections (302, 304, 306, 308) of the bandmap. If an appropriate carrier is found while scanning the SNL, the device reconnects to the serving system. While scanning the subsections of the bandmap, the device creates and maintains a list (312) of suitable carriers. If no carriers are found corresponding to the SNL, a serving cell is selected from the list (312).

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 of security authentication and key management scheme in a multi-hop wireless network is provided herein with a hop-by-hop security model. The scheme adapts the 802.11r key hierarchy into the meshed AP network. In this approach, a top key holder (R0KH) derives and holds the top Pairwise Master Key (PMK—0) for each supplicant wireless device after the authentication process. All authenticator AP take the level one key holder (R1KH) role and receive the next level Pairwise Master Key (PMK—1) from R0KH. The link level data protection key is derived from PMK—1 via the 802.11i 4-way handshaking.

摘要： A system and method for providing a congestion optimized address resolution protocol (ARP) for a wireless ad-hoc network. The system and method enables a node in the wireless ad-hoc network to issue an ARP request without the need to broadcast the request to all of the nodes in the wireless ad-hoc network, to thus minimize radio traffic on the wireless ad-hoc network for handling the ARP request. The node includes an address resolution protocol module which is adapted to generate an ARP request for a media access control (MAC) address corresponding to an Internet protocol (IP) address, and a transceiver which is adapted to transmit the ARP request for delivery to an access point of a network portion, such as a core LAN of the network, without broadcasting the ARP request to a plurality of other nodes in the wireless ad-hoc network. The transceiver can transmit the ARP request to the access point directly or via other nodes in the wireless ad-hoc network.
