Abstract :

In packet radio networks, simultaneously transmitted packets act as multiple access interference. In order to maximize the system performance, the number of simultaneously transmitted packets should be kept at a proper level. This paper proposes a slotted random access protocol with dynamic transmission probability control scheme in the spread spectrum system. In the proposed scheme, the base station calculates the packet transmission probability in the next slot according to the offered loads and then broadcasts it to all the mobile stations. Mobile stations, which have a packet to transmit, transmit packet with the received probability. Simulation results show that the proposed scheme can offer better system throughput and average delay performance than the conventional one.
