What is D2D protocol?

Device-to-Device (D2D) communication in cellular networks is defined as direct communication between two mobile users without traversing the Base Station (BS) or core network.

How does D2D communication work?

D2D communication is a new paradigm in cellular networks [1]. It allows user equipments (UEs) in close proximity to communicate using a direct link rather than having their radio signal travel all the way through the base station (BS) or the core network.

How many modes of operation are in the resource usage for D2D communication?

D2D users in cellular networks usually have three working modes: cellular mode [6], dedicated mode [7], and multiplex mode [8]. The dedicated mode and the multiplexed mode are collectively referred to as the D2D communication mode.

What is resource allocation in D2D communication?

In distributed resource allocation, the resources should be allocated to the D2D links in a distributed way [42]. Each and every D2D link that is involved in direct communication scans the network for any resource that is not used by any other device and utilises that resource for its communication.
