The Selection of the Monitored-Set for QoS Collection Based on Device-Agent

The requirement of QoE is gradually increasing currently. Simultaneously, as the intermedium between the users and network, devices support collecting several QoS parameters which could predict expected QoE for users. However, a large quantity of mobile devices will become the obstacle for the QoS collection due to the costs of collection traffic. To solve it, this paper proposes a framework for collecting QoS based on Device-Agent. And the paper focuses on the Monitored-Set selecting from a large quantity of devices. The Clustering Monitored-Set Selection Model integrates the location of devices, the network topology and the relationship between devices into solving the problem of Monitored-Set selection. At last, the model is verified via simulation and the result analysis is given in this paper.
