Abstract

Device-to-device communication (D2D-C) is one of the breakthrough technologies of the fifth-generation (5G) network that has attracted researchers working in data-regroup applications. It offers great advantages, such as minimum delay, base station load balancing, improved spectral efficiency, and many more. Despite these benefits, efficient resource allocation is one of the major concerns. Existing state-of-the-art solutions are based on game theory, graph theory, etc. The one-to-one Maximum matching scheme offers the best solution in graph theory and has not been explored to its potential. Also, the number of eavesdroppers in the system can affect the existing resource allocation schemes and degrade the system’s performance. This can be taken care of by implementing a D2D-C user access control mechanism, which restricts D2D-C users from having eavesdropping intentions. So, considering these issues, we propose a Fisher Jenks natural break (FJNB) optimization and kernel density estimation clustering-based resource allocation scheme with a D2D-C user access control mechanism. It improves the overall system’s total sum rate and computation time performance.

优化访问控制和高效资源分配，实现 D2D 通信总和速率最大化

设备到设备通信（D2D-C）是第五代（5G）网络的突破性技术之一，吸引了从事数据分组应用的研究人员。它具有极大的优势，如最小延迟、基站负载平衡、提高频谱效率等。尽管有这些优势，但高效的资源分配仍是人们关注的主要问题之一。现有的先进解决方案基于博弈论、图论等。在图论中，一对一最大匹配方案提供了最佳解决方案，但尚未充分挖掘其潜力。此外，系统中窃听者的数量也会影响现有的资源分配方案，降低系统性能。这可以通过实施 D2D-C 用户访问控制机制来解决，该机制可以限制 D2D-C 用户的窃听意图。因此，考虑到这些问题，我们提出了一种基于费舍尔-詹克斯自然断裂（FJNB）优化和内核密度估计聚类的资源分配方案和 D2D-C 用户访问控制机制。它提高了整个系统的总和速率和计算时间性能。
