摘要
通过对无线网络中信道受干扰程度的研究,提出无线信道干扰概率思想,依据干扰概率得到无线信道的通断特性及干扰等级,进而分析无线信道干扰概率与系统可靠度和业务传输成功率等性能指标的关系。利用OPNET工具构建无线网络和算法模型,仿真分析干扰概率对网络性能的影响,为设计无线网络抗干扰路由协议、提高无线网络抗干扰性能提供理论基础。
Through a study on the channel interference degree in wireless network, an idea of wireless, channel interference probability is proposed, based on which the make-break characteristics and interference levels of wireless channel are obtained, and the relationship between wireless channel interference probability and system reliability and traffic transmission success ratio is further analyzed. The wireless network and algorithm model are built through OPNET tool,and the effect of interference probability on network performance is simulated and analyzed, providing a theoretical foundation for the design of wireless network anti-interference routing protocol and the improvement of anti-interference performance of wireless network.
