Design and Measurement Results for Cooperative Device to Device Communication

Abstract

In this chapter, the authors present the simulation and measurement results for direct and single hop device-to-device (D2D) communication protocols. The measurement results will further argument the development of D2D communication and will also help in understanding some of the intricate design issues which were overlooked during theoretical or computer simulations. The measurements were taken on a proof-of-concept experimental testbed by emulating a cellular scenario in which a Base station (BS) and many D2D enabled devices coordinate and communicate with each other to select an optimum communication range, transmit parameters, etc. A testbed (Multi-carrier) was developed using Software Defined radio which incorporates the concept of Spectrum Sharing through static sub-carrier allocation to D2D user by cellular system which will eventually enhance the performance of cellular as well as D2D communication system. Our purposed and deployed protocol have shown significant improvement in received Signal to Noise Ratio (SNR) as compared to conventional direct transmission schemes.
