Emerging Device¿¿¿Centric Communications

Emerging device???centric systems (DCS) such as devices???to???device communications are considered standard components of future mobile networks, where operators/consumers involve their devices in direct communications to improve the cellular system throughput, latency, fairness and energy efficiency. This chapter introduces a new scheme to support emerging features in DCS, where a device???to???device (D2D)???enabled mobile device (a content requester) aggregates the radio resources of multiple mobile devices (content providers) to improve the file transfer latency (FTL), energy efficiency and battery life. This scheme is referred to as devices???to???device (Ds2D) communications. The chapter presents an optimal algorithm for source device and radio interface selection based on the ascending proxy auctions mechanism. The proposed mechanism achieves a higher energy efficiency compared with the conventional D2D communications approach and a lower energy consumption per source device compared with the multi???homing D2D communications approach.
