Abstract: A node on a collision detection protocol based network forces collisions to gain control of the network when it has real time data that needs to be transferred to another node on the network, and then begins transmitting the real time data prior to other nodes gaining control of the network. Each node which has real time data to transfer keeps track of a maximum wait time parameter to determine when the real time data must be transferred to ensure it arrives at a destination on time. As the maximum wait time is approached, the node forces a collision by transmitting even though it senses another node is already transmitting to force the network into a quiet mode. It then starts transmitting the real time data prior to other nodes beginning transmission.
