【摘要】 首先分析了有线网络和无线网络带宽估计机制的区别,然后,在此基础上给出了MANET可用带宽定义,并且从原理上分析了数据帧碰撞概率、回退时间以及信道空闲比例等对MANET中的可用带宽造成影响的因素,同时对各种参数的测量以及估计方法进行了详细介绍,最后展望了带宽估计的应用前景和研究趋势。更多还原

【Abstract】 With analysis of the difference between bandwidth estimation scheme in wired network and wireless network,the available bandwidth in mobile ad hoc network is defined. The factors which infect the available bandwidth including frame collision probability,backoff time and channel utilization are analyzed; meanwhile,the methods of measurement and estimation are also given; finally,the application and research trend of available bandwidth estimation is pointed out.更多还原
