Optimal Targeted Advertising Strategy For Secure Wireless Edge Metaverse

Abstract

Recently, Metaverse has attracted increasing attention from both industry and academia, because of the significant potential to integrate real and digital worlds ever more seamlessly. By combining advanced wireless communications, edge computing and virtual reality (VR) technologies into Metaverse, a multidimensional, intelligent and powerful wireless edge Metaverse is created for future human society. In this paper, we design a privacy preserving targeted advertising strategy for the wireless edge Metaverse. Specifically, a Metaverse service provider (MSP) allocates bandwidth to the VR users so that the users can access Metaverse from edge access points. To protect users' privacy, the covert communication technique is used in the downlink. Then, the MSP can offer high-quality access services to earn more profits. Motivated by the concept of "covert", targeted advertising is used to promote the sale of bandwidth and ensure that the advertising strategy cannot be detected by competitors who may make counter-offer and by attackers who want to disrupt the services. We derive the best advertising strategy in terms of budget input, with the help of the Vidale-Wolfe model and Hamiltonian function. Furthermore, we propose a novel metric named Meta-Immersion to represent the user's experience feelings. The performance evaluation shows that the MSP can boost its revenue with an optimal targeted advertising strategy, especially compared with that without the advertising.

A Survey on Metaverse: Fundamentals, Security, and Privacy

“…3) Networking: In the metaverse, networking technologies such as 6G, software-defined network (SDN), and IoT empower the ubiquitous network access and real-time massive data transmission between real and virtual worlds, as well as between sub-metaverses. Beyond 5G (B5G) and 6G offer possibilities for ubiquitous, real-time, and ultra-reliable communications for massive metaverse devices with enhanced mobility support [34]. In 6G, space-air-ground integrated network (SAGIN) [35] is a promising trend for seamless and ubiquitous network access to metaverse services.…”

“…A two-tier Q-learning based mechanism is devised in [81] to dynamically derive the optimal strategies for each side. In The works [34], [83] study the data availability in metaverse in terms of data synchronization and QoS, respectively. For accurate DT synchronization with its physical counterpart, Han et al [83] propose a hierarchical game for dynamic DT synchronization in the metaverse, where end devices collectively gather the status information of physical objects and VSPs decide proper synchronization intensities.…”

“…Simulation results demonstrate that the proposed mechanism attains a higher accumulated revenue for VSP. By leveraging covert communication methods, Du et al [34] propose an optimal targeted advertising strategy for the VSP to maximize its payoff in offering high-quality access services for end-users while attaining close-to-one detection error for attackers. In their work, the Vidale-Wolfe advertising model is exploited, and a novel metric meta-immersion is introduced to measure users' feelings in metaverse experience.…”

SDN enables the flexible and scalable management of largescale metaverse network via the separation of the control plane and data plane.…”

Joint User Association and Resource Pricing for Metaverse: Distributed and Centralized Approaches

“…Double Dutch auction with deep reinforcement learning was proposed as the solution methodology. In [6], a new Meta-Immersion metric was introduced to measure the quality of immersive experience of a user. Then the authors addressed the allocation problem of the basic bandwidth and acceleration bandwidth, according to different quality requirements of the access services.…”
