关键词：认知无线电 事件驱动 多通道模拟-Multiple-channel simulation system including implementation for protocol statcks 、

simulation of multiple wireless channel and topology of wirless networks，is often used in the field in

simulation in multiple-channel communication system. These kinds of simulation systems resolve the

20 defect of softwares used for simulating multiple channel networks. In this paper, we mainly focus on

the two mechanism of simulation: period-driven and event-driven. Methodology of research and

implementation for node module and channel simulation is proposed.

Key words: cognitive radio　event-driven　multi-channel simulation
