Abstract:

This thesis considers the physical and media access control layer (PHY/MAC) architectures of a device-to-device (D2D) communication protocol for ad hoc networks. We propose an orthogonal frequency-division multiple access (OFDMA) based distributed D2D solution for frequency hopping networks operating with small packet sizes. The main contributions to the literature are adding an average received power estimation method to achieve interference-awareness, and implementing a time slotted connection scheduler to attain efficient spatial reuse. Design aspects are discussed for both peer discovery and connection scheduling stages. Simulation results are presented to demonstrate the potential of the proposed structure from the throughput perspective in networks where a frequency hopping strategy is implemented, and the packet sizes are relatively small as in Bluetooth.
