Integration of 3G Connectivity in PlanetLab Europe Abstract__Distributed research testbeds play a fundamental role in the evaluation of disruptive innovations for the Future Internet. In recent years, the main research funding agencies have promoted several initiatives aimed at designing and building open, large scale, realistic experimental facilities that could be used to evaluate innovative networking architectures, paradigms and services. In this paper, after discussing the main challenges in building such infrastructures, we present how, by leveraging the concept of federation, we managed to introduce a first degree of heterogeneity into PlanetLab Europe, a European testbed federated with PlanetLab, by providing UMTS connectivity to PlanetLab Europe nodes. Our contribution is just a first step of an evolutionary path whose further developments will lead to next generation large-scale heterogeneous testbeds for supporting experimentally-driven research on the Network of the Future (Preliminary results within the same framework of this work have been recently published in Canonico et al. (2007) and Botta et al. (2008)).
Intelligent Video Monitoring System based on 3G Abstract-In order to improve the effect of video monitoring and decrease the rate of false alarm, an intelligent video monitoring system is designed based on 3G telecommunication technology and face recognition teleology. Taking core, this system involves a 3G telecommunication module centered on MUI03 and a protocol of safe command transmission. Thus, this intelligent video monitoring system has multifold functions: long-distance video monitoring, automatic multistage alarming and long-distance backup. Many strict tests have proved this system has met the anticipated requirements, and can be applied into many fields such as long-distance monitoring and household security.
Japanese Telemedical Concept of Ambulatory Application Abstract__Transmission of in-ambulance data without inconveniencing or undue effort by the rescue crew—in other words, automation of in-ambulance activities (measurement/ analysis, activity recording, message transmission)—is essential in implementing uniform medical control standards across the nation. However, the 3G mobile phone has propagation problems at urban area and severe congestions after major disaster to support mobile telemedicine. So we are expecting the Quasi-zenith satellite with nationwide coverage. In near future, we are expecting the data transmission of image of pharygoscopy, motion picture of light reflex, 12-leads ECG, automated ultrasonic echo and vital signs from ambulances to triage center. For example, Thrombolytic agents are reportedly effective even when injected into a vein, if injected in the early stages of acute myocardial infarction, that will reduce medical costs, resulting in high-quality services available uniformly across the nation. This paper describes our basic concept to support ambulatory application.
Joint Session Admission Control Scheme in IntegratedWLAN and 3G Networks Abstract—As heterogeneous wireless networks are deployed and users need more flexible mobility services, there has been a lot of research work about interworking mechanism between widely deployed 3G network and rapidly boarded WLAN (wireless local area network). On the other side, TD-SCDMA (time divisionsynchronous code division multiple access), which combines all the advantage of the TDD (time-division deplex) with CDMA (code-division multiple access), is one of the three main standards of third-generation mobile radio system, and is newly commercialized in China. It is expected to provide enough mobility and higher data rate. So the study of the integration between WLAN and TD-SCDMA will be attractive. In this paper, we propose an efficient joint session admission control scheme that maximize overall network revenue with Qos (quality of service) constraints over both the WLAN and the TD-SCDMA cellular networks. Simulation results illustrate that the overall network revenue earned in the proposed scheme is significant larger than that when the individual networks are optimized independently.
License-exempt: Wi-Fi complement to 3G Abstract__In this paper we compare and contrast the development of Wi-Fi as a license-exempt wireless broadband technology to access the internet with the licensed regime of broadband cellular networks such as 3G. This exploration is based on an assessment of the two different innovation journeys which resulted from two different underlying communication paradigms and two different regulatory regimes, leading to different business models and different diffusions patterns. In concluding we compare the merits of the two cases and derive recommendations for policy and strategy formation.

Modeling of the Electromagnetic Interference Map Generated by 3G Systems Inside Small Aircraft Abstract—The substantial increase in customer demand for office-like communication services during flights is pushing aircraft manufactures to implement wireless solutions inside aircraft. Nevertheless, aircraft safety is a paramount criterion for operators, thus the potential risks posed by such communication systems on aircraft equipment must be carefully assessed and respective countermeasures taken. In this work, we adopt a three-dimensional ray tracing method based on geometrical optics and combine it with electromagnetic field computation to model the interference generated by a 3G cellular system inside the cabin of a typical business jet. The model initially develops a propagation map of the electromagnetic (EM) radiation emitted by the Node B station inside the aircraft to determine the power incident on the receiving antennas of personal electronic devices (PEDs). This is used to establish the transmission power employed by each PED. Subsequently similar propagation maps are generated for each mobile device. All the radio space propagation maps are then vectorially combined to produce an EM interference map at the fuselage.
Multiset Collision Attacks on Reduced-Round SNOW 3G and SNOW 3G Abstract__The stream cipher SNOW3G designed in 2006 by ETSI/SAGE is a base algorithm for the second set of 3GPP confidentiality and integrity algorithms. In this paper we study the resynchronization mechanism of SNOW 3G and of a similar cipher SNOW 3G using multiset collision attacks. For SNOW 3G we show a simple 13-round multiset distinguisher with complexity of 28 steps. We show full key recovery chosen IV resynchronization attacks for up to 18 out of 33 initialization rounds of SNOW3G with a complexity of 257 to generate the data and 253 steps of analysis.
Network Integration in 3G and 4G Wireless Networks Abstract—3G wireless data networks have emerged as the first high speed, ubiquitous data networks. 4G wireless networks are poised to replace 3G networks as the next generation of mobile data networks, but the transition will be lengthy and expensive. Wireless authentication across 3G and 4G data networks is typically an arduous task, requiring complete disconnection from the existing network before performing a lengthy full authentication on the new network. We introduce an efficient interworking method for CDMA2000 1xEVDO and WiMAX data networks that allows existing authentication credentials to be leveraged in more efficient interworking protocols at both tightly- and loosely-coupled network integration levels, as well as a proactive handoff scheme that takes advantage of our tightly-coupled interworking. We perform a detailed simulation and mathematical analysis of our interworking and handoff protocols and find that our interworking scheme reduces interworking delays by up to 75% in the WiMAX to CDMA case and 85% in the CDMA to WiMAX case.
