Abstract:

The recent advances in wireless technologies made it possible to inter connect every device wirelessly to the Internet, which is called as Internet of Things (IoT). 5G cellular communication research community has been compelled to design solutions for the IoT along with conventional data communications and voice/video over IP networks. The IoT plays a critical role in the modern society with smart cities, smart power grids and other applications. These applications demand ultra low power and low cost solutions. To meet such diversified requirements, novel physical layer need to be designed. In this paper, a novel accessing technique with the LTE procedures defined by 3GPP has been used to cater the needs of IoT devices generated random traffic. A new system with Offset Quadrature Amplitude Modulation (OQAM) and bi-orthogonal frequency division multiplexing (BFDM) is simulated using Matlab Software along with BFDM QAM and LTE based OFDM. In this paper, the performance of BFDM-OQAM system is compared with OFDM and BFDM QAM systems under Line of Sight fading conditions such as Rural Line of Sight (RLOS), Highway Line of Sight (HLOS), and Urban Approaching Line Of Sight (UALOS).

I. Introduction

The evolution of Internet of Things (IoT) has been instrumental in changing our daily life beyond our imagination and is the stepping stone for 5G. 5G Research is driven by the Machine-to-Machine (M2M) communication, ubiquitous broadband connectivity, and the tactile internet. The Internet of Things (IoT) would be the predominant driver for the 5G cellular communication networks [1] growth. The reach of IoT spans across every area of lifestyle and business providing the advantages of improved customer engagement, optimization of resources, enhanced connectivity, and efficient data collection from various sources on continuous basis. Efficient access to the 5G networks for the random traffic generated by these IoT devices is a bigger challenge sine these are inactive for longer durations and the periodic internet access is done for trivial or incremental update without human intervention. In 5G networks, hundreds of interconnected IoT devices will be a norm and handling such an exponential growth of sporadic traffic with the existing LTE random access procedures is a herculean task.
