Performance Analysis of Device to Device Communications Overlaying/Underlaying Cellular Network
Minimizing the outage probability and maximizing throughput are two important aspects in device to device (D2D) communications, which are greatly related to each other. In this paper, first, the exact formulas of the outage probability for D2D communications underlaying or overlaying cellular network are derived which jointly experience Additive White Gaussian Noise (AWGN) and Rayleigh multipat...
متن کاملSocial- and Mobility-Aware Device-to-Device Content Delivery
Mobile online social network services have seen a rapid increase, in which the huge amount of user-generated social media contents propagating between users via social connections has significantly challenged the traditional content delivery paradigm: First, replicating all of the contents generated by users to edge servers that well “fit” the receivers becomes difficult due to the limited band...
متن کاملPerformance analysis of device-to-device communications underlaying cellular networks
Device-to-device (D2D) communications underlaying cellular networks are considered to be promising communication modes to improve network radio resource efficiency and provide higher transmission data rates to devices close to each other. However, when D2D communications reuse cellular resources, the resulting interference will cause significant performance loss to cellular users. In this paper...
متن کاملPower Efficiency for Device-to-Device Communications
The concept of device-to-Device (D2D) communication as an underlay coexistence with cellular networks gains many advantages of improving system performance. In this paper, we model such a two-layer heterogenous network based on stochastic geometry approach. We aim at minimizing the expected power consumption of the D2D layer while satisfying the outage performance of both D2D layer and cellular...
متن کاملSmart - Device - to - Smart - Device Communications
Device-to-device (D2D) communications have been identified by the Third Generation Partnership Project (3GPP) as a potential candidate technology to offload heavily used cellular communication systems. Even though D2D communications has been around in industry and research for the last two decades, the 3GPP decision to include this concept in the cellular context is groundbreaking. There are se...
