Probing based wireless channel bandwidth estimation and its application to video streaming over wireless networks

Abstract

We propose an efficient bandwidth estimation method to wireless networks. In the proposed method, the available bandwidth (AB) is estimated based on a packet pair probing technique (PPPT) that is a well-known mechanism for measuring the capacity of an end-to-end path without any information of network routers. To adapt the PPPT to the wireless network, in this paper, the cross traffic and the capacity variation of wireless link are considered to estimate the AB. We also introduce a video streaming application using the estimated AB. Experimental results show that the proposed method does not only estimate the accurate bandwidth, but also improve the performance of video streaming application over wireless networks.

Available Link Bandwidth Based Network Selection in Multi-access Networks

“…In this paper, we propose a network selection in heterogeneous environment based on available bandwidth estimat ion by using bootstrap approximation. When there are various types of probing techniques available for bandwidth estimat ion in literature [4][5][6][7][8][9][10][11][12][13]. An ideal probing tool provided accurate estimate of available bandwidth prior to sending data packets [4].…”

“…The utilization of network connection is measured by using tri packets method defined in probing technique [6]. Packet pair probing technique is used by wireless network for bandwidth estimation while considering the capacity and the cross traffic variat ion of wireless link [7]. The probe gap model was designed for both one-hop and multi hop path, under the case of path persistent cross traffic.…”
