Internet traffic monitoring and analysis have been a very essential way in network management and optimization for the ISP. GPRS networks are increasingly carrying Internet traffic for Web browsing, Email and online games etc. In this paper, we proposed a Hadoop based cloud computing platform for high-speed network traffic analysis. We experimentally prove that our platform is capable of analyzing...
In the idea to create a realistic model of mobility and traffic for the networks of 3rd and 4th generation, we have studied many techniques of modeling and planning. Our choice was for the real network traces exploitation techniques, mainly because compared to other techniques this technique is very adapted to the real modeling. Although this technique is most convenient, it has many disadvantages...

Since peer-to-peer (P2P) systems are dominating in Internet traffic, there were several attempts to implement it in mobile wireless networks, in particular in GSM/GPRS and UMTS networks. In this work basic and hidden problems which prevent it from successful implementation are studied as well as some proposals and improvements are presented. Mainly this work is focused on specific features of mobile...
Network mobility (NEMO) aims providing seamless Internet connectivity for the network which is moving around with vehicles. Multiple care of addresses (MCoA) registration was also proposed as an extension. This paper studies the seamless Internet connectivity of mobile router (MR) which is equipped with WLAN, CDMA and GPRS interfaces simultaneously. Concretely, a smooth inter-interfaces hand-off algorithm...
In this paper we evaluate four different metrics for non intrusive bottleneck detection based on TCP counters. This work is based on the full TCP statistics recorded on five days spread over the last one and a half year within the core network of a mobile network operator in Austria. Scatterplots, so called ldquofootprintsrdquo, were generated counting the number of packets and the number of retransmission...
