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 (R(3)) protocol) suitable for code-division multiple-access (CDMA ) wireless data networks is proposed. The communication between two da ta terminals is initiated by hand-shaking (request and acknowledgement stages) followed by data-packet transmission (pair-up stage), using t he receiver-based signature codes for multiple-accessing. The two-dime nsional continuous-time Markov chain was used to model and analyse the behaviour of the network. The analytical results show that a respecta ble improvement in throughput-delay performance can be achieved, apply ing the proposed protocol to unslotted DS/SSMA packet-radio networks, when compared to other reported code protocols.
