Paper Abstract

A novel MAC protocol which was able to support data, voice and rt-VBR video traffics based on PRMA protocol was proposed for communication network in near space. PRMA frame was divided into two parts, one part slots are allocated for rt-VBR video and data traffics. The other part slots are allocated for voice traffic. The proposed MAC protocol had good ability to support mixed traffics by means of optimized combination of slots in a frame, traffic separation and traffic priority. Three performance parameters: voice and video packet loss probability, average delay of data packets and channel utilization were analyzed in simulation. The simulation showed that the proposed MAC protocol had advantages on increase of channel utilization with the guarantee of quality of service. Finally the optimized reservation time slots of 36 for rt-VBR video traffics and maximum channel utilization of 85% were given.
