Impulse radio Ultrawideband D2D-based localization for ultra-dense 5G networks

The 5G prospect of seamlessly connected global devices with delay-Tolerant communication, millisecond latency and gigabits per second data rate suggests the need for location-Aware devices, systems and networks. This requires new methods for high resolution positioning services. It is however believed that Impulse Radio (IR) Ultrawideband (UWB) promises better positioning methods for accuracy-critical situations expected in 5G setting. This paper discusses the IR UWB D2D-based localization for ultra-dense networks. It proposes an IR-UWB D2D WWAN along with its cluster formation scheme. This is followed with performance evaluation of the cluster lifetime and system throughput. Also proposed is an IR UWB D2D-propagation-based combined localization and communication scheme (UD-CLOCS). Results of related UD-CLOCS performance assessment experiments have been impressive while some highlights are presented in this paper. It is believed that the proposed solutions have potential for robust and cost efficient localization in 5G setting as well as prospect to decongest licensed spectrums in 5G wireless environment.
