1、中国科学技术大学博士学位论文无线网状网媒体访问控制及路由协议研究姓名:束永安申请学位级别:博士专业:通信与信息系统指导教师:洪佩琳20070401中国科学技术大学博士学位论文无线网状网的路由协议需要自适应快速多变的环境,如动态变化的流量以及快速多变的无线链路质量等。那些为有线网络所设计的传统路由协议,并不能很好处理无线网状网中常见的快速变化。第五章首先介绍了与无线网状网路由协议关联性较强的Adhoc路由协议,然后分析了比较有代表性的无线网状网路由协议,最后提出了一种基于干扰模型的无线网状网自适应路由策略IBA
2、R,通过选择具有最小干扰的路径,显著提高路由的效率。为适应动态变化的网络环境,IBAR定期对路由进行分布式自适应调整,在WMN网关节点进行负载均衡。为解决自适应路由策略引起的路由振荡,本文提出了行之有效的解决方法。通过仿真表明,与AODV和HWMP协议相比,IBAR能显著改善咖q吞吐量等性能。论文中提出的算法和机制经过了理论分析和计算机仿真的验证,可以用于无线网状网络中,对设计无线网状网MAC协议和路由协议也具有较高的参考价值。关键词:无线网状网(舢),信道分配,M^c协议,路由协议,干扰,自适应ⅡAbstr
