Abstract
As we transition into the era of B5G/6G networks, the promise of seamless, high-speed connectivity brings unprecedented opportunities and challenges. Among the most critical concerns is the preservation of location privacy, given the enhanced precision and pervasive connectivity of these advanced networks. This paper systematically reviews the state of knowledge on location privacy in B5G/6G networks, highlighting the architectural advancements and infrastructural complexities that contribute to increased privacy risks. The urgency of studying these technologies is underscored by the rapid adoption of B5G/6G and the growing sophistication of location tracking methods. We evaluate current and emerging privacy-preserving mechanisms, exploring the implications of sophisticated tracking methods and the challenges posed by the complex network infrastructures. Our findings reveal the…
