Consultancy Services in Modelling and Measuring the Network Capacity of the 3G Networks in Hong Kong
(Funded by Office of the Telecommunications Authority)

The Consultancy Report is written to propose a reference capacity model for OFTA in order to implement the Open Network Access (ONA) policy. The methodology and approach of the involved measurements will be explained, followed by the data processing and result analysis. Based on the findings of these extensive field measurements a reference model is proposed to characterize the "capacity" of a 3G network.

(Funded by Innovation and Technology Fund)

Sponsors:
  • IVHS Division, Mark IV Industries
  • ANSEN Electronics Company
  • e-jing Technologies
  • ITE (Holdings) Limited

    To develop the core technologies in RFID tags and readers and related networking and to apply the RFID technology to logistics management. The proposed research will investigate most of practical issues in building a RFID system and its network implementation. The emphasis of the project is placed on developing active RFID systems at UHF frequency band. On top of the systems, an advanced logistics management platform will be implemented and tested in a cross docking environments.

    The project is co-developed by the Department of Electronic Engineering, Information Engineering and Systems Engineering & Engineering Management, the Chinese University of Hong Kong.

  • A Wireless Mesh Network Testbed
    (Funded by Shun Hing Institute of Advanced Engineering)

    Wireless mesh network is a hot topic in the recent research. Most research papers of wireless networks nowadays rely on simulation, especially when mobility is added. However, it is obviously that simulation is unable to capture the complex signal irregularity in wireless channel, like in an indoor environment. This motivates the building of a wireless mesh network Testbed. The objective of this project is to setup a wireless mesh network testbed in the two engineering building by deploying about 30-40 mesh routers in different floors and locations. Various research experiments can then be performed in this network.

    An Extensible Measurement Platform on Mobile Devices for Healthcare Monitoring and Personal Wellness Applications
    (
    Funded by Office of the Telecommunications Authority)

    It is now common for mobile handheld devices like smartphones and PDAs to have a range of sensing (accelerometers, cameras, microphone), localization (GPS) and communication (3G, WiFi, Bluetooth) capabilities, in addition to computing. The proliferation of these powerful and programmable mobile devices has led to the design of various new applications that take advantage of the range of capabilities that these mobile devices offer. In particular, one of the more important and practical applications that can benefit from the sensing and data collection capabilities of mobile devices is in the area of healthcare monitoring and personal wellness. In this project we propose to design and develop an open, extensible, configurable and scalable measurement platform on mobile devices. Using this measurement platform, we will build various tools to monitor and collect the different data streams (movement data from accelerometers, acoustic data from microphones, location data from GPS, etc) generated as a result of the user's behavior and daily activities.

    An Extensive Distributed Measurement Platform for Analyzing Quality-of-Experience (QoE) of Multimedia Applications over Wireless Networks
    (
    Funded by Innovation and Technology Fund)

    Sponsors:

    • SmarTone Mobile Communication Limited

    Wireless service providers need to be able to continuously monitor the network Quality-of-Service (QoS) and the Quality-of-Experience (QoE) received by its users. This is so that the providers can collect the necessary feedback to optimize their networks, in order to achieve customer satisfaction while operating cost-effectively. With the increasing computational capabilities of mobile devices, it is now possible to instrument these programmable devices with automated network QoS and QoE measurement software, to conduct large-scale, extensive field measurements in a distributed, scalable and yet cost-effective manner. To realize this endeavor, we propose to design and develop a configurable, scalable and extensible measurement platform on mobile devices that will allow us to monitor network-level QoS performance metrics, do real-time mining of the collected data and perform real-time estimation of the user-perceived QoE of multimedia streams.

    Medical Alert System
    Students: HO Wai Kit, LI Kin Fai

    The number of sensors for medical measurement is increasing due to the increasing demand of medical diagnose and treatments. Therefore it is more difficult for medical personnel to monitor all sensors. In order to improve the efficiency, we have designed a new system called Medical Alert System. When the sensor reading becomes abnormal, medical personnel can be alerted by handheld devices such as Pocket PC, mobile phone.


    Mobile TV for us (MTV4S)
    (Previously named Mobile Extension for MythTV)

    Students: SUEN Ho Yan, LAM Chi Ho

    "Mobile extensions on MythTV" extends the TV functions of MythTV to mobile devices. It allows users to watch both live and recorded TV, and manage the recording schedules on their mobile devices, such as cellular phones and PDAs. In addition, time shifting and full playback control are supported for convenient playback.

    IPv6 Performance Testbed
    Students: LAW Yuk Nam, Gordon LAI

    Organizations of all types, especially in international and governmental markets, there are increasing pressure to migrate from the well known and universal IPv4 standard towards the newer IPv6 standard. IPv6, people may have heard of that, however, what it really is and its performance on the real internet is still a mystery, especially from the perspective of end users. In order to excel form the theoretical analysis, we setup a testbed of seven computers, installed with different operation systems, to test on the performance of IPv6.

    Wireless Sensor Network for Patient IV Monitoring

    As the demand grows in social healthcare services, the interest in the applications of wireless information technology is also increasing for reducing the cost and improving the medical services quality to patients. In this technical report, we describe the design and implementation of a wireless sensor network for monitoring the intravenous (IV) fluid infusion system attached to a patient. The key feature of our system is that the information (IV condition and location) is transferred continuously to a server while the patient is in motion. This experimental testbed in MobiTeC has been useful for conducting research in wireless sensor networks, including service differentiation, multi-hop routing, and object tracking.


    Network Tracer - Tools Designed for Monitoring the Network I/O of Skype

    Initially, this set of tools is designed for monitoring the network I/O of a common VoIP application - Skype. In later development, it is found that this useful tool box offers a generic usage in Windows environment. Users can easily find out all of the TCP and UDP packets of a specific application. Skype Tools contains several tools which can help us to extract all the network traffic only related to Skype, so that we can analysis the mechanism of Skype easily.
