SALALAH: An Omani researcher has come up with a solution for re-allocation of the unutilised bandwidth to be used fairly by all as well as performance model for macro/micro cells network which supports fast and slow mobility users.
As the cellular technology is becoming one of the fastest growing forms of mobile communications, Dr Zaid Zabanoot, Dean, Salalah College of Applied Sciences, has thrown ample light on wireless network through his research on ‘Resource management schemes in wireless networks’.
Dr Zabanoot has done extensive research on the topic to find that “the bounds of an existing communication network infrastructure have been extended by cellular technology via connecting mobile units to public networks operated by the local exchange or long distance carriers, in order to make special features and functions specific to both cellular and public networks available to all users.”
Global standards, according to him, have been developed to provide voice and data services anytime and anywhere regardless of user mobility, while satisfying their diverse quality of service requirements.
Commenting on the motivation behind doing the research and compiling it into a book, Dr Zabanoot said: “wireless network communication systems have been experiencing a dramatic and continuous growth in the number of subscribers, thus placing extra demands on system capacity. The area has tremendous scope for research, as something new is happening on daily basis in the field.”
Oman’s IT standards, according to Dr Zabanoot, are quite satisfactory. Still he calls for more and more research in the field to keep pace with global developments. Offering solution to radio co channel interference, Dr Zabanoot says, “To avoid radio co channel interference, the group or channels assigned to one cell must be different from the group of channels assigned to its neighbouring cells.
However, the same group of channels can be assigned to the two cells that are far enough apart such that the radio co-channel interference between them is within a tolerable limit.”
Dr Zabanoot outlines the objectives of the research as “Developing an analytical model for priority handover mechanisms and optimise the number of channels assigned to handover calls, with the aim of minimising the drop probability under given network scenarios.
