Device-to-Device Communication in 5G Cellular Networks: Challenges, Solutions, and Future Directions

شما اینجا هستید

In a conventional cellular system, devices are not allowed to directly communicate with each other in the licensed cellular bandwidth and all communications take place through the base stations.‎ In this talk, we envision a two-tier cellular network that involves a macrocell tier (i.e.‎, BS-to-device communications) and a device tier (i.e.‎, device-to-device communications).‎ Device terminal relaying makes it possible for devices in a network to function as transmission relays for each other and realize a massive ad hoc mesh network.‎ This is obviously a dramatic departure from the conventional cellular architecture and brings unique technical challenges.‎ In such a two-tier cellular system, since the user data is routed through other users’ devices, security must be maintained for privacy.‎ To ensure minimal impact on the performance of existing macrocell BSs, the two-tier network needs to be designed with smart interference management strategies and appropriate resource allocation schemes.‎ Furthermore, novel pricing models should be designed to tempt devices to participate in this type of communication.‎ We will provide an overview of these major challenges in two-tier networks and proposes some pricing schemes for different types of device relaying.‎
