Abstract:
With the rise of content-centric networks and small cell networks (SCN), the volume of data transmission has witnessed a significant surge in both uplink and downlink directions. To tackle the ensuing challenges of network congestion and bottlenecks in backhaul links within B5G networks, data caching has emerged as a popular solution. However, caching for uplink transmission in a distributed B5G scenario poses several challenges, including duplicate matching of contents and users' lack of awareness about cached contents. Additionally, there is a need to maximize available space by caching the most popular contents in a distributed manner. This research paper presents two schemes for uplink transmission in distributed B5G SCNs. The first scheme focuses on content matching to eliminate duplicates among distributed caches, while the second scheme redistributes unduplicated cached contents among distributed caches based on their available space. These approaches aim to enhance energy and spectral efficiency by reducing unnecessary uploads and optimizing distributed content caching. The analysis shows that the proposed scheme outperforms the existing schemes by improving the cache hit ratio, cache hit probability, overall distributed cache efficiency, and diversity by 29.17%, 74.89%, 24.17%, and, 80%, respectively. Furthermore, the throughput, energy efficiency (EE), and spectrum efficiency (SE) of the access network by 17.78%, 78%, and 18%, respectively. Besides that, the EE and SE of both the sidehaul and backhaul links of the SBSs improved.
