Systematic Sampling and Cluster Sampling of Packet Delays
Thomas Lindh · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2006
Based on experiences of a traffic flow performance meter this papersuggests and evaluates cluster sampling and systematic sampling as methods toestimate average packet delays. Systematic sampling facilitates for exampletime analysis, frequency analysis and jitter measurements. Cluster samplingwith repeated trains of periodically spaced sampling units separated by randomstarting periods, and systematic sampling are evaluated with respect to accuracyand precision. Packet delay traces have been used in simulation studies.The motivation for this kind of cluster sampling is to avoid performance deteriorationdue to possible periodic patterns in packet delays. The conclusion ofthis study is that systematic sampling and cluster sampling methods are efficientalternatives, or complements, to simple random sampling.
