The Optimization of Node Configuration in a Mixed Network for Quality of Service

ITC/USA 2008 Conference Proceedings / The Forty-Fourth Annual International Telemetering Conference and Technical Exhibition / October 27-30, 2008 / Town and Country Resort & Convention Center, San Diego, CaliforniaMorgan State University's iNET project is the development of a complete network architecture to enhance telemetry performance. Existing telemetry standards employ an RF link standard which allows only unidirectional data transfer from a test article (TA) to a ground station over a dedicated channel per TA. This limits the capacity of the system as resources are not efficiently utilized. Additionally, this standard does not allow data exchange between Over the Horizon TAs and the ground station. Their data must be recorded for subsequent retrieval by test engineers. The growth of telemetry demands that spectrum resources are maximized to increase transfer capacity. Real time data exchange capability is essential to success in telemetry. Bidirectional streaming of data to both near and over the horizon TAs is desired with no compromise of Quality of Service for real time applications. The network approach addresses these demands by allowing telemetry data to be multiplexed over a shared radio channel to and from the TAs. A mixed cellular and mobile adhoc network (mixed network) has been shown to satisfy the capacity and coverage elements of iNET requirements. This paper begins with an introduction to the iNET objective, continues with some background information on the major technical elements applied in this endeavor and finally shows that an optimum node configuration can be achieved and maintained in this mixed network using clustering techniques to include the joint optimization of the Quality of Service, Signal-to-Noise ratio, and Interference requirements as outlined by the iNET Needs Discernment.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
