Abstract: A method and apparatus for link adaptation is provided. A node stores a set of transmit parameters and corresponding selection probabilities for each of the transmit parameters. The node stochastically selects a particular transmit parameter based on the selection probabilities, and then transmits a packet according to the particular selected transmit parameter. From received transmission feedback information, the node derives performance statistics, and uses the performance statistics to specify an estimated performance function for the particular transmit parameter. The node updates a selection probability computation function (SPCF), and uses the SPCF to generate updated selection probabilities corresponding to each transmit parameter in the set of available transmit parameters.

Abstract: A node in a wireless communication system announces a channel switch operation to facilitate a smooth transition to other channel. The node detects a requirement to discontinue communications at a first channel and sends a message to a plurality of neighboring nodes in response to detecting the requirement. Generally, the message comprises at least a reason for discontinuation of communications at the first channel and a duration for the channel switch operation after which the node is available for communications at the first channel or an alternate channel. Each of the plurality of neighboring nodes can determine based on the message and the neighborhood conditions a requirement to scan alternate channels to initiate communications with other nodes.

Abstract: 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.

Abstract: A Wireless Router (WR) aggregates information regarding the emergency calls based on their context and routes the aggregated emergency information to the correct portal which directs the aggregated emergency to appropriate Public Safety Answering Point (PSAP). The information aggregation is automatically triggered when the number of calls exceeds the multihop capacity to the egress point. The PSAP responds to the emergency situation by sending a response message via the Portal. The WR multicast/broadcasts the response message to the mobile devices which initiated the emergency calls. The response message generally includes emergency instructions based on incident type and location. Further, a call-back list is created for users whose emergency calls were not completed. By using the call-back list PSAP personnel can initiate calls to end users to provide assistance in emergency situations.

Abstract: Unified groupcast data frame formats are provided for improving the efficiency of groupcast communications in multihop wireless mesh networks, and significantly reducing bandwidth consumption. The unified groupcast data frame formats modify existing BSS data frame formats by inserting a mesh end-to-end sequence number into a field that is normally reserved for a sequence control field. In some implementations, a time-to-live (TTL) value can also be inserted into a QoS control field.
