摘　　要：为改进时隙式随机多址协议的吞吐率性能,文献[13]对信道占用存在的3种事件分配了不同的时隙类型,其中空闲和碰撞事件分配短时隙,成功事件分配长时隙.基于以上时隙划分,提出在报文接入过程中加以概率控制的新思想,并采用平均周期方法进行分析.结果表明,系统吞吐率性能明显改善,数学解析和计算机仿真结论一致.In order to improve the performance of slotted random multi-access protocol, three types of competitive channel events were allotted in different slots in document 13, among which short slots were allotted for the idle and collision events; long slots were assigned for success events. Based on the above slots division, a new idea of P-probability control in packet access is proposed and gets the better throughput per-formance. By using average cycle method, the conclusions of mathematical modeling and computer simulation are consistent.
