An adaptive transmission based dynamic packet reservation multiple accesss protocol
自适应动态分组预约多址协议

This paper proposes an adaptive transmission based dynamic packet reservation multiple access protocol for flexible and efficient support of multimedia services with different quality of services under dynamically changing traffic and channel condition. In this scheme, all idle slots are classified as Free, Long Available and Short Available. Long and short messages can be transmitted in idle period of voice traffic. At the same time, protocol can adjust dynamically according to the number of Free slot the criterion of instantaneous traffic and adaptive transmission scheme is used to increase system efficiency further. Computer simulation confirms that the proposed system with perfectly selected parameters is effective in achieving larger capacity of multimedia communication systems.
