<h2 id="data-delivery-in-non-cooperative-d2d-communication">Data delivery in non-cooperative D2D communication</h2> <p>Existing data delivery protocols in D2D communications mainly assume that mobile nodes willingly participate in data delivery, share their resources with each other, and follow the rules of underlying networking protocols. Nevertheless, rational nodes in real-world scenarios have strategic interactions and may act selfishly for various reasons (such as resource limitations, the lack of interest in data, or social preferences).<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> </p> <h2 id="d2d-applications">D2D applications</h2> <p>D2D Communications is used for </p> <ol><li>Local Services: In local service, user data is directly transmitted between the terminals and doesn't involves network side, e.g. social media apps, which are based on proximity service.</li> <li>Emergency communications: In case of natural disasters like hurricanes, earthquakes etc., the traditional communication network may not work due to the damage caused. Ad hoc network can be established via D2D which could be used for such communication in such situations.</li> <li>IoT Enhancement: By combining D2D with <a href="/facts/Internet_of_things/rwwGAxn3">Internet of things</a> (IoT), a truly interconnected wireless network will be created. Example of D2D-based IoT enhancement is vehicle-to-vehicle (V2V) communication in the Internet of Vehicles (IoV). When running at high speeds, a vehicle can warn nearby vehicles in D2D mode before it changes lanes or slows down.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a></li></ol> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Machine_to_machine/tdsbXlnr">Machine to machine</a></li> <li><a href="/facts/Peer-to-peer/wCCdPb0H">Peer-to-peer</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Asadi, Arash; Wang, Qing; Mancuso, Vincenzo (24 April 2014).
