    摘要: Techniques are provided for distributed admission control (AC) in a mobile ad hoc network (MANET). When the source node transmits a new communication stream (NCS) toward a destination node, other nodes allow transmission of the NCS during a temporary admission period even though the NCS has not yet been admitted. The nodes can determine whether the NCS causes degradation of any existing communication stream(s) (ECSs) supported by that node based on existing QoS requirements associated with the ECSs. In some implementations, nodes which determine that they are unable to support ECSs transmit an indicator which notifies other nodes that admission of the NCS is denied by that node. By contrast, if none of the nodes transmit an indicator during the temporary admission period, then the NCS is “admitted” to the MANET and the source node is permitted to keep transmitting the NCS, a variation thereof or another new communication stream.

    摘要: Some embodiments are directed to a method and apparatus for performing resource negotiation in a station implementing a direct communication link with at least one other station on an Orthogonal Frequency-Division Multiple Access (OFDMA) data channel. The station scans sub-channels on the data channel for base headers included in predefined position in transmissions sent on the sub-channel. The station then decodes a base header in at least one selected sub-channel to obtain parameters of a channel reservation. The obtained parameters are stored in a channel utilization table. The station selects a resource on the data channel in at least one of time or frequency that the station has observed to be free using information from the channel utilization table. The station then begins a resource negotiation process about the selected resource.

    摘要: A method is provided which enables the connection of nodes out of communication range while minimizing the energy consumption in standby nodes. Specifically, the present invention provides a method to control the wake up rate of standby nodes in a multi-hop communication system. An access point collects, processes, and refines statistical information regarding one or more system parameters; determines a wake up rate based on the statistical information and one or more historical information; and transmits the wake up rate to nodes in its coverage area. A node receives the wake up rate; and periodically changes from a sleep state to a wake up state at the wake up rate to support routing functions for providing multi-hop communication to the one or more access points.

    摘要: An overlay communication system (120) aides determining a route between nodes (101-103) in an underlay communication system (110). In particular, when a first node (102) wishes to discover a route to a second node (103), the first node notifies the overlay communication system, which notifies all nodes in the underlay communication system of the desire. Both the first and the second nodes begin flooding the underlay system simultaneously. When a node in the underlay system hears both the flood messages from the first and the second node, the overlay communication system is notified and stops all flooding. The route information is then provided to the first and the second nodes via the overlay communication system.
