| 摘 要： | Ad Hoc Probe是目前测量无线网络路径带宽的主要方法,由于发送探测分组数目固定,当负载较轻时,仅需要几组探测报文就能够获得正确的样本,所以限制了无线Ad Hoc网络的动态性。针对Ad Hoc Probe算法的不足,提出了AdHoc TP算法,一次发送三个报文,组成两个报文对,通过比较两个报文对的时间间隔和最小时延和提高样本的过滤速度,从而使测量速度更快。Qual Net仿真的结果表明,Ad Hoc TP算法能够正确地测量出有线/无线Ad Hoc混合网络的带宽,而且测量速度较快。

| Abstract: | Ad Hoc Probe is a main method for the path bandwidth measurement in wireless network.Since the number of sending probing packets in the Ad Hoc Probe algorithm is fixed,a few probing packets is needed when the load is light,so it limits the dynamics of Ad Hoc network.To solve these problems,a new model of Ad Hoc TP algorithm is proposed.The Ad Hoc Probe sends three back-to-back packets to form two pairs,at the same time,and the filtering velocity of samples and accelerate the measuring speed is improved by c... |
