Self-similar traffic assessment on QoS service classes of WiMAX network
Dedi Rahmawan Putra, Kai‐Wei Ke, Ho‐Ting Wu · 2009
WiMAX features several QoS service classes to schedule different types of traffic. In this paper, we will assess the existence of self-similar traffic for each service class. The experiment starts by capturing the traffic data with a dedicated SNMP-based network management system (NMS). NMS manages the deployment of fixed WiMAX network defined in IEEE 802.16d-2004 Standard and records the inbound and outbound traffic for specific object IDs (OIDs). We consider several criteria to generate the traffic for our WiMAX test-bed network such as QoS service class, traffic intensity, and application type. The recorded traffic then will be analyzed using variance plot, and RS-plot. The result shows various degree of self-similarity for different types of QoS service classes and traffic intensities.
