摘要： A type of channel access, Clique Activated Multiple Access (CAMA), is disclosed which allows neighboring nodes to form cliques for the purpose of supporting a broadcast channel. CAMA operates using only local knowledge, meaning it can scale to large networks. It also has the potential of requiring less channel resources than node allocation. In addition, it would lend itself well to an application like push-to-talk voice where only one transmitter per neighborhood is active (except for relay nodes.

摘要： A heuristic logical neighborhooding technique is applied to dynamic wireless networking. Logical neighborhooding, provides for the formation of logical neighborhoods across a plurality of channels when such need arises due to increased network density. The technique utilizes a time division multiple access structure including bootstrap slots, broadcast slots, and traffic slots.

摘要： A method of communicating over a network of nodes is disclosed. According to the method, it is determined whether a first node forms part of an interconnected sub-network within the network. Broadcast slots are assigned to the first node if the first node is part of the sub-network. The first node is permitted to use the assigned broadcast slots to broadcast data to other nodes. Nodes within one hop of the first node but not forming part of the sub-network are permitted to use an assigned broadcast slot if the first node is not using the broadcast slot.

摘要： A method of selecting linked metric measurements from at least one of open loop and closed loop measurements is disclosed. The method includes sending by a first node a first radio communication and receiving by a second node the first radio communication over a communication link. The method also includes estimating by a second node dynamics of the communication channel using at least one of the variance and mean deviation of linked metric measurements. The link metric measurements are at least one of symbol error rate (SER), packet error rate (PER), frame error rate (FER), bit error rate (BER), signal to noise ration (SNR), and received signal strength (RSS). The method also includes the use of the above link metric measurements by the second node as Open Loop metrics and the sending back of these metrics to the first node for use a Closed Loop metrics by the first node. The method also includes categorizing the dynamics of the communications channel into one of at least two groups based on the estimate. Further still, the method comprises selecting, based on the chosen group, the use of at least one of closed loop link adaption and open loop link adaption of communication link parameters.

摘要： A method for establishing simultaneous communications between nodes having neighboring nodes in a multi-hop network of transceiver nodes arranged in neighborhoods includes determining the quality of communication links between the nodes of a neighborhood and adjacent neighborhoods. A table of quality data is stored representing the quality of communication links between nodes of the neighborhood for each node. A set of performance criterion of desired service in the neighborhood is stored. A set of possible link assignments between ones of the nodes in the neighborhood is generated from the table of quality data based upon a maximized performance criterion of desired service in the neighborhood. Link assignments are then allocated between nodes of the neighborhood based upon the desired performance criterion.

摘要： A method and apparatus for the receiver directed assignment of receive slots in a dynamic assignment communication system. The apparatus including a memory component storing communication assignment data for a plurality of time slots in a time multiplex structure and a processor component capable of identifying a set of available time slots from the plurality of time slots. The apparatus being capable of assigning itself a receive slot, which can be a broadcast receive slot, from the set of available time slots. The method involves establishing a network wherein network communication is accomplished via assignment of specific time slots of a time multiplex structure. The method further involves determining a set of available time slots suitable for reception, by a receiving node, of a communication from a neighboring node, the receiving node then assigning to itself a receive slot from the set of available time slots. The method and apparatus are also capable of handling transmissions from a plurality of neighboring devices during a broadcast receive slot. This can be accomplished by a scheduling technique, a random access technique or a code division multiple access technique.
