A near-optimum mac protocol based on the distributed queueing random access protocol (dqrap) for a cdma mobile communication system

This paper presents and analyses a new near– optimum random access protocol. The proposed access scheme is suitable for a CDMA environment and minimises the total number of spreading codes needed to achieve a certain throughput. It is based on distributed queues and a collision resolution algorithm....

Sumario:This paper presents and analyses a new near– optimum random access protocol. The proposed access scheme is suitable for a CDMA environment and minimises the total number of spreading codes needed to achieve a certain throughput. It is based on distributed queues and a collision resolution algorithm. Computer simulations have been carried out to validate the analytical model and the obtained results show that the protocol has very good stability and delay performance, even compared with medium access protocols using more available spreading codes
