| 摘 要： | 提出一种适合于分簇Ad Hoc网络的高效自适应TDMA时隙分配算法EASA. EASA采用动态调整帧长以及根据簇内节点MAC层缓存队列长度进行自适应的时隙分配，解决了传统TDMA时隙分配算法中低传输速率节点占用不必要时隙的问题. 多个场景的实验结果表明，与传统TDMA时隙分配算法以及802.11相比，EASA可以大大提高网络吞吐量，很好的提高网络整体性能.

| Abstract: | TDMA has been introduced into ad hoc networks because of its ability to provide collision-free packet transmission. Slot assignment protocol is a vital part of TDMA technique which can affect the throughput of the network significantly. EASA, a novel efficient adaptive slot assignment protocol for clustered ad hoc TDMA network is proposed. The effectiveness of EASA has also been verified by simulation experiments in different scenarios. It is proved by simulation results that EASA can increase throughput of the network dramatically. |
