The degradation of available bandwidth along wireless multi-hop network leads to the network congestion, and causes the deteriorations in streaming quality (the increasing delay, packet loss). The Network Measurement Methodology for detecting congestion quantitatively, such as available bandwidth measurement considering real-time property, is of major importance in avoiding the deteriorations. Problems with existing common methods are that measurement-time gets longer, and congestion is also invoked by probe-traffic. In addition, in case that available bandwidth changes in short period, measurement deviation deteriorates because of long measurement-time. We propose the method for available bandwidth measurement in high-speed and low-load using the switching control of probing-destination in wireless multi-hop network, and evaluate performance. Our method divides network into sub-interval(called PATH), and monitors probe’s Round-Trip-Time(RTT) over each PATH with sequentially switching probing-destination. By comparing probe RTT monitored over different PATH, our method detects the PATH including the wireless link of available bandwidth. As an experimental result, we confirmed that the measurement-time is shortened by 94%, and probe-traffic is reduced by 89% compared to the existing common method. Moreover, in case that available bandwidth changes in shorter period than the measurement-time of the existing common method, our method improves measurement deviation by 79%. |
