AHP-Based Resource Utilization Scheme at the Network Edge with Ad Hoc Network Gateway

Abstract

A sensitive problem in active learning classroom affecting the performance of Internet video streams is caused from the network degradation during the times of overloaded traffics. In this paper, we investigate how such a problem can be solved by a mean of edge computing system running at a gateway device so that virtualized services for transcoded video streams can be offered at the local ad-hoc network. In addition, we explore the use of multi-criteria decision making mechanism with AHP method for suggesting sensible network resources that can yield possible video qualities. Based on the result obtained by empirical network traces on a video clip transfer, our proposed solution selects lower levels of network utilizations than those of DASH server for similar video resolutions and frame-rates. Hence, it is beneficial for empowering the teacher to deploy flexible network policies in times of congestion at ease so that the residue of network resource can be given to some other essential tasks.
