摘要： 无线自组织网络(Ad Hoc网络)中实时业务的传输需要网络协议提供较为可靠的服务质量保证(Qos保证)，而现有多址接入协议一般未能提供较好的Qos支持。在单步信道预约思想的基础上，提出了一种基于更为可靠的多步信道预约机制的多址接入协议，其利用实时业务分组的周期性特点，对无线信道资源进行多步预约，从而保证了实时业务的可靠传输。仿真实验表明，相较于单步信道预约机制，多步信道预约机制对网络的多址接入性能有较好的改进。

Abstract: Real-time traffic transmission over wireless Ad hoc networks requires authentic and reliable QoS assurance from wireless network protocols, which is not available from most of the current MAC protocols. Considering the periodicity of real-time traffic, a MAC protocol based on multipl}step channel reservation mechanism was proposed, which guarantees more reliable transmission for real-time frames. Simulation results and analysis obviously indicate that the protocol raises the network performance to a more excellent level.
Key words: Multiple-step reservation, MAC protocol, Ad hoc, QoS
