Searching for Self-Similarity in GPRS

Abstract. Based on measurements in live GPRS networks, the degree of selfsimilarity for the aggregated WAP and WEB traffic is investigated by utilizing six well established Hurst parameter estimators. We show that in particular WAP traffic is long-range dependent and its scaling for time scales below the average page duration is not second order self similar. WAP over UDP can also determine the overall traffic scaling, if it is the majority traffic. Finally we observe that the minor traffic exhibits a larger Hurst value than the aggregated traffic, in case of WAP as well as in case of WEB traffic.
