Triple-receiver-based code protocol for unslotted DS/SSMA packet-radio networks and its performance analysis

An unslotted DS/SSMA packet-radio protocol (the triple-receiver-based code (R3) protocol) suitable for code-division multiple-access (CDMA) wireless data networks is proposed. The communication between two data terminals is initiated by hand-shaking (request and acknowledgement stages) followed by data-packet transmission (pair-up stage), using the receiver-based signature codes for multiple-accessing. The two-dimensional continuous-time Markov chain was used to model and analyse the behaviour of the network. The analytical results show that a respectable improvement in throughput-delay performance can be achieved, applying the proposed protocol to unslotted DS/SSMA packet-radio networks, when compared to other reported code protocols.
