Efficient radio resource allocation scheme for 5G networks with device-to-device communication

<p>A vital technology in the next-generation cellular network is device-to-device (D2D) communication. Cellular user enabled with D2D communication provides high spectral efficiency and further increases the coverage area of the cell, especially for the end-cell users and blind spot areas. However, the implementation of D2D communication increases interference among the cellular and D2D users. In this paper, we proposed a radio resource allocation (RRA) algorithm to manage the interference using fractional frequency reuse (FFR) scheme and Hungarian algorithm. The proposed algorithm is divided into three parts. First, the FFR scheme allocates different frequency bands among the cell (inner and outer region) for both the cellular and the D2D users to reduce the interference. Second, the Hungarian weighted bipartite matching algorithm is used to allocate the resources to D2D users with the minimum total system interference, while maintaining the total system sum rate. The cellular users share the resources with more than one D2D pair. Lastly, the local search technique of swapping is used for further allocation to minimize the interference. We implemented two types of assignments, fair multiple assignment, and restricted multiple assignment. We compared our results with existing algorithms which verified that our proposed algorithm provides outstanding results in aspects like interference reduction and system sum rate. For restricted multiple assignment, 60-70% of the D2D users are allocated in average cases.</p>

Radio Resource Allocation and Mobility Accessment of 5G Wireless Network Using Adaptive Q-LEACH Routing Protocol

The implementation and operation of a Fifth Generation (5G) network aims to achieve a maximum speed, low potential, improved flexibility, and a change in requirements and technologies from service-oriented to user-oriented. The users need resource allocation and management that is effective. Established networks’ closed infrastructure and ossified services result in particularly in wireless networks, inefficient resource allocation and underutilized network resources. On the basis the standard of a service provider’s utility benefit then customer gratification, various allocation strategies are suggested. Wireless system based 5G another research area aimed at supply distribution and 5G access links is network. In this project, radio resource allocation and mobility assessment of 5G wireless network LEACH routing protocol is implemented. In terms of wireless networks, various architectural integrations of other wireless technologies such as 5G, LTE, Wi-MAX, and so on are highlighted. Furthermore, the project focuses on resource allocation approaches and strategies for cellular networks, as well as comprehensive criteria for future 5G networks
