Analytical performance evaluation of Internet access over GPRS and its comparison with simulation results

Integrated Wireless Access for Videoconference From MPEG-4 and H.263 Video Coders With Voice, E-mail, and Web Traffic

“…This latter model has recently often been used by researchers in the field (e.g., [9], [10]). According to [7], the distributions of the random variables concerning the composition of web requests are the following: 1) size of web request: lognormal (5.84, 0.29), with mean = 360 bytes and standard deviation = 106.5 bytes.…”

General Packet Radio Service Physical-Layer Performance Simulation

“…A de-burst formatting and de-mapping block are then implemented for extracting the additional bits inserted in the transmission process. After theses blocks, the received packet is de-interleaved, rate matched, and decoded by Viterbi hard-decision decoder [3] respectively. The next process is the extraction of tail, BCS, and USF bits.…”

“…In this way a very flexible access is possible while idle users can still be online always and anywhere. A detailed description of GPRS is given in [1][2][3][4].…”

OMNeT++ Models for Resource Allocation in Wireless Networks

“…The problem of resource allocation in (E)GPRS is very complex, and because of that the pure analytical approaches do not provide reliable results, as shown in [13]. Hence, most researchers have chosen to develop simulation models for studying this problem.…”

“…Hence, most researchers have chosen to develop simulation models for studying this problem. Industrial research and sometimes even academic research uses complex emulators, like POTOMAC, described in [5], or GPRSim ( [18], [13]). Our goal was to avoid the complex interactions that appear in such an emulator between the GPRS protocols, and to develop a simulation model that allows different levels of details in modelling (E)GPRS.…”
