BARA: A Battery Energy and Data Rate Aware Resource Allocation Algorithm for QoE in D2D Communication Underlaying Cellular Networks

This paper proposes a battery and data rate aware resource allocation (BARA) algorithm for quality of experience (QoE) provisioning in D2D communication underlaying cellular networks. The BARA algorithm takes into account the data rate and battery consumption of a user device in spectrum resource allocation, and aims to improve the average QoE of D2D pairs in the system. To this end, the Peukert's law is introduced as a battery model to predict the battery consumption of a user's device. A new QoE model is defined based on the typical MOS model, taking into account a logistic function, to measure the QoE of a user in the system. Moreover, a satisfaction degree function is introduced to decide each D2D user's priority in resource allocation. Simulation results demonstrate that the BARA algorithm can significantly improve the average QoE of D2D pairs in the network without obviously affecting the overall throughput of the system.
