—5g is known as the fifth generation technology in the cellular communication networking, cellular companies started to introduce 5g networks in 2019, this network is a upcoming successor for the 4g communication networking. This provides connectivity to most cellular users. Similar to its predecessors, 5G networks are the cellular networks in which the coverage area is divided into small areas called cells. D2D communication generally plays vital role in the future 5g networking as it has very low-latency for the data transmission between the users. This can be operated in a new mode named licensed or unlicensed spectrum. Social network in mobile and D2D communications have are better and future techniques which can support local services in 5G networking. The process of integrating between mobile social networking and D2D communications in 5G networks faces major roles like exploiting the relationship between the cellular users and managing interference, energy and spectrum to get better results of D2D communication.
