一种适于AD-HOC网的改进型TDMA协议

An Improved TDMA Protocol in Ad-hoc Network

本文针对AD-HOC网络对多址接入协议的吞吐量大、时延小等要求,提出了固定分配机制和自适应竞争机制相结合的改进型TDMA协议。介绍了该协议的时隙竞争、使用策略,最后用仿真图形证明了该协议的吞吐量及时延性能优于固定分配TDMA协议和PRMA协议。

Considering that AD-Hoc network requires high IO and less delay for multi-address connection. An improved TDMA protocol basing on fixed slot distribution protocol and self-adaptive competition protocol is introduced in this paper. The competition and use method of the slots are introduced. Furthermore, the performance of the proposed protocol is analyzed, and the simulation results show that the performance is achieved better than both fixed slot TDMA protocol and PRMA protocol.
