Summary:
Data?Over?Cable Service Interface Specifications (DOCSIS) permit the addition of highspeed data transfer to an existing Cable TV (CATV) system. In this paper, simple transmission protocol is considered. We propose random slot multiple access algorithm for contentions resolution. In this algorithm, p-persistence value for each user is prepared for mini-slot selection, and also, mini-slot in each slot and users are divided into groups. The user in each group will access to the allocated mini-slot with the designed persistence value. Then, the algorithm can reduce the collision problem when two or more users access to the same mini-slots. The system performances are analyzed and the result is shown in throughput and time delay of system.
