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. |
