Performance-bound analysis of the new DS/SSMA protocol for wireless data networks

Abstract

The new code protocol (the R3 protocol) for DS/SSMA wireless data networks proposed recently is examined further and an analytical method is given of studying its delay and throughput bounds. In this protocol, the communication-initiation process between two terminals uses handshaking packets (REQ and ACK packets), followed by the data packet. Different chip rates are utilised in transmissions of different packets to avoid destructive collisions between them. All packets are encoded by receiver-based codes. It is shown that the throughput lower bound of this protocol is about 0.24 when the normalised offered channel-traffic load is equal to one, and that the protocol offers stability to the network even at a very high offered channel-traffic load.
