| 摘 要： | 本文提出了一种适用于Adhoc网络的动态时隙分配TDMA算法——IP-TDMA算法,该算法以一种新颖的方式在固定TDMA的基础上叠加了优先级竞争机制,既有最差性能保障,又有较高信道利用率。通过采用一种特殊的帧结构,P-TDMA算法还可以避免信令分组的碰撞,是一种有效而又可靠的广播动态时隙分配TDMA算法。仿真结果表明,无论在吞吐量还是迟延方面,P-TDMA算法都比固定TDMA表现出更好的性能。

| Abstract: | In this paper, a dynamical TDMA algorithm (P-TDMA) algorithm is proposed for mobile Ad hoc network. P-TDMA introduces contention mechanism based on fixed TDMA thus provides finite delay guarantee and improved channel utility rate. By using a special frame structure, this algorithm can avoid the collision of control packets and it is an efficient and reliable broadcast dynamic slot assignment TDMA algorithm. Simulations show that the new algorithm has better performance in both throughput and end to end delay than fixed TDMA. |
