Performance Analysis of Large-Scale Symbiotic Ambient Backscatter Networks Using Matern Cluster Process

Symbiotic ambient backscatter communication (AmBC) is emerging as a promising technology, offering the potential for spectrum- and energy-efficient wireless communication. In symbiotic AmBC, passive backscatter devices (BDs) not only share spectrum resources but also harness the power of primary system to transmit their own information. Evaluating the performance of large-scale symbiotic AmBC systems presents substantial challenges. This letter employs the stochastic geometry methodology to model and analyze symbiotic AmBC networks. BDs locations are modeled as a Matern cluster process (MCP) with cooperative receivers (CRs) as parent points. Using this model, we analyze and derive successful transmission probabilities for typical base station (BS) and typical BD, drawing upon stochastic geometry principles. Simulation results validate the accuracy of our derived formulas and offer valuable insights for extending symbiotic AmBC technology to large-scale wireless communication. Symbiotic AmBC technology holds great potential for the future of wireless communication systems. By further exploring and developing this technology, we can expect advancements in energy efficiency, spectrum utilization, scalability, and integration with other emerging technologies.
