Improving the quality of service in modern communication networks is the most important challenges facing service providers due to the large number of subscribers and the limited available resources, and the increasing demand for broadband services provided by these networks and at speeds and quality of service that satisfy the subscribers' desires.
The increase in capacity is the most important service quality requirement, as D2D technology recently contributed in improving the performance of cellular networks and increasing their capacity with better support for quality of service because of its ability to introduce more resources and contribute to improving the level of services provided.
In this paper, the focus was on resource allocation in D2D communications, by studying OFDM access technology adopted in the fourth generation 4G with the use of D2D system in order to increase the capacity and thus improve the quality of service by supporting subscribers and improving their experience in reaching the broadband applications .
The new resource allocation algorithm relies on dividing the cells into a group of rings, some of which are allocated to cellular communications, and others for D2D communications, so that resources are shared and reused in a more flexible and effective way with minimum interferencelimits. The results show the possibility of increasing the capacity while increasing the number of rings and reducing interference.
