Energy Efficient D2D Application for Increasing Battery Usage of Smartphones

Abstract

to-device (D2D) communication architecture underlying Long Term EvolutionAdvance (LTE-A) technology in hexagonal cell environment. The paper also includes the goal to develop a technique for efficient positioning of user equipment and implementation of connection handover for this D2D communication ProSe. The technique for handover is based on Observed Time Difference Of Arrival (OTDOA) positioning approach along with the Positioning Reference Signal (PRS), mentioned inRelease 9 of LTE technology. It is shown through simulations that the proposed system will reduce the probability of outage i.e. the probability of the UEs running out of battery power before their target usage time. The scheme will also reduce the probability of connection dropping, thereby improving performance of whole system.
