The Carrier Sense Multiple Access with Collision Detection works on the basis of the back-off algorithm which gives a range of time slots for a particular device and a particular packet, once a collision is detected. The node selects a random time slot to retransmit and each time if collision occurs, the probability of success keeps on increasing for that node only, decreasing the probability for other nodes in the network, who might want to transmit packets in an empty time slot. I propose an external device which allocates specific time slots for the nodes who might want to transmit packets after a collision has occurred. This method also utilizes a clock on each node and the channel must be divided into multiple bandwidth gaps.
