    Adaptive Location Update Schemes for Continuous Cell Zooming Algorithm in Wireless Networks 

    Tun, Khin Cho; Kunagorn Kunavut (2015)

    Continuous cell zooming algorithm is a potential dynamic cell zooming algorithm for energy-efficient operation of mobile wireless networks. In this algorithm, location management strategy (location update process) is required to know the location of the farthest user in each cell to perform cell zooming. However, the application of conventional periodic update scheme in continuous cell zooming algorithm can lead to a high signaling cost. Therefore, in this paper, two adaptive location update schemes, namely, Time-Adaptive Periodic Update ...

    An Overview of Cell Zooming Algorithms and Power Saving Capabilities in Wireless Networks 

    Tun, Khin Cho; Kunagorn Kunavut (2014)

    Cell zooming has emerged as a potential strategy to develop a green communication system in our society and it has become an essential research area of wireless communication. Aiming to highlight the trend of existing cell zooming algorithms and their power saving capabilities, this paper reviews a number of cell zooming algorithms that have been proposed in the literature. Static cell zooming algorithms are effective for off-peak hours and their maximum power saving capability is 50% since off-peak duration is typically not more than ...

    Performance Evaluation of Dynamic Cell Zooming Algorithms in Omni-directional and Sector-based Cells 

    Tun, Khin Cho; Kunagorn Kunavut (2014)

    This paper evaluates and highlights the performance of three dynamic cell zooming algorithms applied in both omni-directional and sector-based networks. A possible framework compatible with dynamic cell zooming algorithms for user’s location detection is presented. The performance of each cell zooming algorithm is simulated in terms of power saving and possible outage in a full-day operation. According to simulated results, there is no significant difference between the performance of each algorithm and others at low traffic hours, but ...
