Conflict avoidance with transmission timing and path mutually restrained responsively to wireless environment changing

摘要

A communication control apparatus is adaptive to changes in a wireless communication environment to control transmission timing and path reciprocally between network nodes to thereby avoid transmission collisions and congestions. A transmission timing control calculator contends with other nodes for a band to transmit a data signal to control a transmission timing of its own node. A path control calculator determines transmission paths for transmitting data signals within the bandwidth for the own node obtained by the transmission timing control calculator. A data signal transmitter transmits a data signal to a destination node on each transmission path determined by the path control calculator. The transmission timing control calculator and the path control calculator provide each other with state information on processing, and use the provided state information as a constraint condition to control the bands of the own node and of links between the own and destination nodes.
