A Unified Architectural Model for Multi-Connectivity in Heterogeneous Wireless Networks

The convergence of the metaverse and ubiquitous computing presents a new paradigm for applications that connect humans, machines, and their virtual counterparts. These applications are built upon wireless networks and demand massive data transfers between device clusters. While several technological candidates are in active development to meet these needs, the question remains whether technological progress alone can keep pace with their growing requirements. This paper argues that, alongside advances in wireless technology, the current layered architecture must be reimagined to inherently promote network heterogeneity. This approach allows multiple physical layer technologies to be integrated and individual layer protocols to better adapt to the network environment. We propose a novel augmented network model with a physical abstraction layer to seamlessly integrate diverse wireless technologies, enabling application data to be distributed across multiple network interfaces. We present an analytical proof of concept to evaluate its performance using key metrics such as throughput, packet delay, and server utilization. The results demonstrate that our proposed model significantly improves throughput and minimizes packet delay under heavy network loads, outperforming single-interface solutions. This work proves the feasibility and substantial performance benefits of wireless heterogeneity in future communication networks.
