ABSTRACT:
A method of communicating data in a multinodal peer network communication system is disclosed in which the data is transmitted in accordance with an established priority scheme. The method uses two techniques to ensure that higher priority data is transmitted before lower priority data. In one technique, decreasing priority time-windows are established by each node of the system following the end of a transmission on a shared transmission medium. Subsequently, data is transmitted when the priority of the data matches or exceeds the priority of the time-window. In the other technique, data collisions on the shared medium are resolved by use of the priority time-window technique in combination with the use of a pseudo-random back-off timer.
