摘要： A wireless communication network control node method for use in a wireless communication network comprising a plurality of nodes operable to directly sense other nodes, a computer program product and network control node operable to perform that method. The method comprises: determining for each node in the network, an indication of direct neighbour nodes; grouping the nodes into node clusters such that each node in the network belongs to one node cluster and each node in the same node cluster can directly sense all other nodes in that cluster, and selecting a set of node clusters such that the total number of node clusters in the network is minimised; assessing, for a selected network performance objective, how many simultaneous signals can be successfully decoded by a node in the network and calculating, based on the assessment, a simultaneous signal group number; comparing the number of node clusters in the selected set of node clusters with the calculated simultaneous signal group number; and modifying the selected set of node clusters in dependence upon the simultaneous signal group number. Arrangements described provide a method of clever network organization that combines CSMA approaches and Successive Interference Cancellation (SIC) processes to optimize overall throughput. Some arrangements introduce code-based carrier sensing to CSMA/ CA to enhance overall capacity.

摘要： In an adaptive cluster forming and scheduling method for ad-hoc networks (802.15.4, Zigbee), dependent on received energy level and the detected periods of high and low energy levels, above or below a threshold, it is determined whether a normal traffic situation, a traffic overload situation or a hidden node situation exists. Packet transmission failure is a further criteria for the scheduling method. The clusters consists only of one-hop neighbours.
The method comprises: collating measured changes in energy levels received over a transmission channel of a wireless telecommunications network; and determining a current condition of the transmission channel by establishing a conformance of the measured changes with expected changes in energy levels when operating under at least one condition. By collating the actual measured changes in energy levels, an accurate, dynamic indication of the energy levels being experienced on the transmission channel can be determined. Also, by correlating the measured changes of the transmission channel when operating in accordance with a particular condition, the conformance or not of the channel with that condition can be determined in order to provide an accurate indication of the current condition of the transmission channel. This avoids having to rely on historic information which may only be relevant to the condition of the channel at previous points in time or having to rely on empirical information which may not be of sufficiently fine granularity either quantitatively or temporally to enable a detailed assessment of the current condition of the transmission channel to be determined. Also, by measuring changes in energy levels, the cause of any non-conformance with a particular operating condition may be derivable, which may not be possible with other indicators.

摘要： Methods of scheduling network node transmission in a wireless communication network, computer program products, a network node gateway and a network node are disclosed. One method comprises causing allocation of each network node of the wireless communication network to at least one of a plurality of clusters of network nodes, each cluster of network nodes comprising only those network nodes which detect transmissions from every network node within that cluster; and scheduling transmissions by network nodes within each of the plurality of clusters to be performed using resources of a transmission separation scheme allocated to be shared by network nodes within that cluster of network nodes. Through this approach, inter-cluster transmissions avoid collision or interference since they are scheduled to be transmitted using different resources. Also, because each network node in the cluster is able to detect or sense transmissions by other network nodes within the cluster, no collisions or interference should occur as a result of intra-cluster transmissions (i.e. transmissions within each cluster). This helps to improve the performance of the wireless communication network, particularly those which operate the contention-based channel access technology Carrier Sensing Multiple Access / Collision Avoidance (CSMA/CA) to deliver their traffic to a destination node.
