  • EMBC - Home Area Network for optimizing telehealth services--empirical simulation analysis.
    Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and, 2014
    Co-Authors: Mohib A. Shah, Mohamed H. Khadra, Dagan Feng
    Abstract:

    Telehealth applications such as Video-over-IP and remote sensor monitoring are rapidly growing in utilisation and it has now expanded to the patient's Homes. These Telehealth applications are, however highly delay sensitive and require high quality (and bandwidth priority) in order to provide satisfactory performances. However, at the patient's Home Area Network (HAN) environment, typically there is no Internet traffic management system which highly affects the quality of these applications. As HAN expands its capacity by adding new devices in its Network, the need for a Network management system become urgent and necessary. In this study, we propose an infrastructure based method to improve Telehealth application quality by managing the quality and distribution of the Internet traffic among the connected devices in a HAN environment. We setup a HAN environment using existing devices readily available at Home and tested the setting with typical Telehealth application needs that includes Video-over-IP, VoIP, data and other multimedia traffic. Our simulation results showed that our method is capable of providing better services. Our method indicated that it can provide ~11% lesser packet-loss under 12Mbps background traffic, while increasing 10% of the CPU load for Traffic management.

  • ISTT - Performance investigations of frequency agile enabled TelosB testbed in Home Area Network
    2014 IEEE 2nd International Symposium on Telecommunication Technologies (ISTT), 2014
    Co-Authors: Rozeha A. Rashid, Muhammad Rezan Bin Resat, Mohd Adib Sarijari, Nur Hija Mahalin, Mohd Shahril Abdullah, A. Hadi Fikri A. Hamid
    Abstract:

    Home Area Network (HAN) consists of several wireless technologies and appliances that normally operate in the ISM 2.4-GHz band. This spectrum sharing environment can introduce interference problems and prevent peaceful coexistence especially for low power radio devices. Therefore, it is significant that these radio devices are spectrum agile as to avoid harmful interference and utilize the spectrum reliably. In this paper, the performance of a ZigBee Frequency Agile (FA) technique implemented on TelosB testbed is studied experimentally. The measurement results show that this technique can effectively overcome the interference caused by the Wi-Fi-based devices by changing the operating frequency of the ZigBee's FA-enabled testbed to the channel with the least interference level. In addition, the testbed with FA achieves throughput improvement by about 86%, reduces delay by 73% and enhances transmission energy efficiency by 64% as compared to the testbed without FA. Consequently, this proves that the FA mechanism can guarantee a seamless communication as well as incurring low transmission cost.

  • ICPADS - Coexistence of Heterogeneous and Homogeneous Wireless Technologies in Smart Grid-Home Area Network
    2013
    Co-Authors: Mohd Adib Sarijari, Anthony Lo, Mohd Sharil Abdullah, Sonia Heemstra De Groot, Ignas G.m.m. Niemegeers, Rozeha A. Rashid
    Abstract:

    In a Home environment, a Smart Grid Home Area Network (SG-HAN) platform facilitates collection and delivery of power consumption information for load profiling and informed decisions on energy management. However, one of the main challenges in HAN is the overcrowded unlicensed 2.4-GHz ISM frequency band, occupied by several types of radio technologies such as ZigBee, Bluetooth, and WiFi. It is crucial that those technologies coexist peacefully to allow each user of the radio technology to fulfill their communication goals. In this paper, we present a potential coexistence scenario in SG-HAN for homogeneous and heterogeneous wireless technologies. The coexistence impact on SG-HAN performance is then modeled and analyzed. The numerical results show significant performance degradation due to the interference for devices in close proximity with the interfering sources in a spectrum sharing environment where in the worst case scenario, SG-HAN communication is almost impossible.

  • internet access to heterogeneous Home Area Network devices with an osgi based residential gateway
    Ubiquitous Computing, 2007
    Co-Authors: Sherali Zeadally, Priya Kubher
    Abstract:

    Home Area Networks are proliferating rapidly in many residential Homes. These Networks are being designed to enable remote access and control to services and contents such as music, video, and data. It remains a significant challenge to design a Home Network that exploits different protocol architectures and standards while allowing interoperability among them. We describe the design and implementation of an architecture (known as a residential gateway) that: enables full interoperability among different technologies by exploiting the Open Service Gateway Initiative (OSGi) technology; provides secure internet access to heterogeneous devices connected to a Home Area Network.

  • demand side management through Home Area Network systems
    International Journal of Electrical Power & Energy Systems, 2018
    Co-Authors: Grzegorz Bazydlo, Szymon Werminski
    Abstract:

    Abstract The increasing demand for power in the Electrical Power System (EPS) causes a significant increase of power in the daily load curve as well as transmission line overload. The large variability in energy consumption in the EPS combined with unpredictable weather events can lead to a situation in which, to save the stability of the EPS, power limits must be introduced or even industrial customers in a given Area have to be disconnected, which causes financial losses. Nowadays, a Transmission System Operator (TSO) is looking for additional solutions to reduce peak power, because existing approaches (mainly building new intervention power units or tariff programs) are not satisfactory due to the high cost of services in combination with an insufficient power reduction effect. The paper presents an approach to reduce peak loads with the use of Home Area Network (HAN) systems installed at residential units. The algorithm of the HAN system, executed by the HAN controller, is modeled using Unified Modeling Language (UML). Then using model transformation techniques, the UML model is translated into Verilog description, and is finally implemented in the Field Programmable Gate Array (FPGA). The advantages of the proposed approach are that with only a small loss of residential user comfort, there is a gain in energy reduction for a relatively small cost, an effective and convenient design of the HAN algorithm, and the flexible maintenance of HAN systems. The latter gain is possible thanks to using modern FPGAs, which allow for dynamic reconfiguration of the HAN controller. It means that a HAN algorithm of a selected user can be exchanged without power interruption of other residential users. A practical example illustrating the proposed approach and a calculation of the potential gains from its implementation are also presented.
