Device-to-Device Communications for National Security and Public Safety
IEEE Access, 2014 Device-to-device (D2D) communications have been proposed as an underlay to long-term evolution (LTE) networks as a means of harvesting the proximity, reuse, and hop gains. However, D2D communications can also serve as a technology component for providing

MOCA: Multiobjective Cell Association for Device-to-Device Communications [PDF]
IEEE Transactions on Vehicular Technology, 2017 It is widely accepted that device-to-device (D2D) communication is envisaged to become the key enabler of direct localized communication between mobile nodes in future wireless networks. However, little attention has been paid to an important aspect that can potentially affect both the performance of D2D and cellular transmissions, which is that of the

Optimizing The Spatial Content Caching Distribution for Device-to-Device Communications
, 2016 We study the optimal geographic content placement problem for device-to-device (D2D) networks in which the content popularity follows the Zipf law. We consider a D2D caching model where the locations of the D2D users (caches) are modeled by a Poisson ...
