中文摘要：
提出了一种动态时隙控制的双概率随机多址接入MAC（DSTPMA）协议,用户终端以p1概率侦测空闲信道,以p2概率检测忙信道,并在发送状态调整时隙定位后接入信道发送信息分组。通过对多通道的DSTPMA协议的建模分析,得到了控制协议的系统吞吐量。仿真实验结果表明,理论分析与仿真结果相一致。
英文摘要：
A two-dimensional probability random multi-access protocol based on dynamic slot control（DSTPMA） for ad hoc network was presented.Packets arriving during the idle time slot would be transmitted in the following time slot with probability p1,while those arriving during the transmission period would sense that the channel was busy and would detect for transmissions with probability p2.User terminal to adjust the sending state after location of access channel time slot to send packets.The throughputs of the DSTPMA protocol were obtained.The results show that the simulation is in concordance with the theoretical analysis.
