Abstract :
A new wireless medium access control scheme is proposed for implementing collaborative codes on the carrier sense multiple access with collision avoidance (CSMA/CA) protocol. To simplify the analysis, a new backoff algorithm is suggested that is simple to implement and to model. Markov chain analysis is used for modelling the proposed CC-CSMA/CA protocol. The resulting model describes the regular CSMA/CA protocol as a special case. Protocol performance measures were studied such as throughput, packet acceptance probability, average energy required to successfully transmit a packet, average packet delay and channel utilisation. It is found that CC-CSMA/CA offers improvements over a system that uses CSMA/CA.
