Abstract

Aimed at the situation that channel source is wasted seriously when traffic is not uniform belong all of the nodes in a TDMA net, a dynamic TDMA protocol (CS-TDMA) utilizing channel sense is was developed. The CS-TDMA protocol based on the TDMA protocol frame, and the node with CS-TDMA protocol counts counted the number of packets from other nodes for estimating their traffic. When the timeslot is remainder, it sends sent an ATS (access to send) message to the busiest node for informing the node to send data until the timeslot was exhaust. Simulation results shown that CS-TDMA protocol had better performance than TDMA protocol on the parameters of end-to-end delay, network throughput and message delivery. Especially, the delay advantage was prominent when the traffic had a big gap between nodes.
