Abstract

Abstract: The radio model in OPNET is not suitable for multi-channel scenarios. It can not give physical carrier-sensing state correctly while channel is switching. The problems which forbid multi-channel simulations in OPNET are analyzed. A new radio model which supports the transceivers of a node to switch between multiple channels is also proposed. And the radio model with the multi-channel MAC protocol simulations in wireless Ad Hoc network scenarios is certified.

Key words: multi-channel, Ad Hoc network, MAC protocol

摘要： 分析OPNET仿真环境中现有的无线信道建模方案，针对其在多信道仿真中的问题，提出一种新的无线信道建模方案，以弥补原有方案在节点进行信道切换时无法实时侦听信道状态的缺陷，保证动态多信道环境中物理载波侦听的实时性。通过对无线自组织网络多信道MAC层协议的仿真及仿真数据的分析，验证了新方案适用于多信道网络的场景仿真。

关键词: 多信道, 自组织网络, MAC层协议
