Topic
Stochastic Geometry-Based Modeling and Analysis of Cognitive and Energy Harvesting D2D Communication in Cellular Networks
Abstract
While cognitive radio enables spectrum-efficient wireless communication, radio frequency (RF) energy harvesting from ambient interference is an enabler for energy-efficient wireless communication. In this talk, I will present a model for cognitive and energy harvesting-based device-to-device (D2D) communication in cellular networks. The cognitive D2D transmitters harvest energy from ambient interference and use one of the channels allocated to cellular users (in uplink or downlink), which is referred to as the D2D channel, to communicate with the corresponding receivers. A D2D transmitter can communicate successfully with its receiver only when it harvests enough energy to perform channel inversion toward the receiver, the D2D channel is free, and the signal-to-interference-plus-noise ratio (SINR) at the receiver is above the required threshold; otherwise, an outage occurs for the D2D communication. The model will be analyzed using tools from stochastic geometry and the performance of the proposed communication system model will be evaluated in terms of SINR outage probability for D2D and cellular users. Numerical results will be shown to demonstrate that energy harvesting can be a potential alternative to power cognitive D2D transmitters while achieving acceptable performance.
