在对现有无线移动网络的Mac层传输机制进行介绍和理论分析的基础上,给出了各种传输机制在实际无线多跳移动环境下的仿真运行结果。仿真结果表明,现有的无线移动网络中的Mac层传输机制并不能适应无线多跳Ad hoc网络环境。在对仿真结果分析的基础上基于TDMA机制提出了一种改进的Mac层传输方法。仿真结果表明,该改进的传输机制相比现有的无线传输机制在无线多跳环境下具有更好的稳定性和链路公平性。
On the basis of analysis Mac layer transmission mechanism of wireless mobile network, the simulation results of these transmission mechanisms was given under wireless multi-hop mobile environment. An ameliorative transmission mechanism was proposed based on TDMA. The simulation result shows that this ameliorative mechanism has better stability and link fairness.
