Abstract:
In a wireless packet radio mesh topology communications system of the type having a plurality of interconnected nodes, a communications method between nodes comprising:dividing time into synchronous frames of known length, within each frame, providing time slots in accordance with a prearranged schedule for each pair of neighboring nodes during which each node exchanges control information with a communicating node, thereby providing synchronous control channel time slots, between each pair of communicating nodes, using said exchanged control information at each communicating node for scheduling asynchronous transmission or reception of data in between the control channel time slots, thereby providing a data channel amidst the control channel, whereby each note has regularly scheduled times for sending and receiving control information, with gaps in the times remaining after exchanging the prearranged schedule of control information, the gaps available for use as a data channel by said scheduling.
