摘　　要：为提升移动自组织(MANET)网络效率,动态时分多址(TDMA)时隙分配算法已经成为MANET网络的研究热点之一。提出了一种新颖的固定分配与动态竞争结合的媒体访问控制(MAC)层协议算法。该算法能在保证基本话音通信需求的基础上,根据不同业务特点动态调整时隙,保证网络对空闲时隙资源竞争使用的效率。仿真结果表明,相对于固定分配时隙算法,该算法大幅度提高了MANET网络的效率。t In order to improve the MANET network efficiency,dynamic TDMA time slots assignment algorithm now becomes one of the hot research topics in MANET network.This paper proposes a new algorithm combining static allocation with dynamic contention in MAC protocol.Based on ensuring the basic communication requirements of users ,this algorithm can adjust in dynamic mode the time slots according to different business characteristics, so that it can make efficient use of slot resource.The simulation results show that compared with the static allocation algorithm, the proposed algorithm can significantly improve the efficiency of MANET network.
