The OTDOA Based Location Updating Algorithm for Fast D2D Connection Handovers
This work includes the goal to develop a technique for efficient positioning of user equipment and implementation of connection handover for device to device (D2D) communication application. This D2D application, being addressed as Battery Deposit Service (BDS), is a utility for optimizing battery of smartphone by reducing energy consumed in communication over network. Addition of an energy efficient positioning & handover strategy for D2D connections will allow the system to perform better with an increased quality of service (QoS). The technique for handover is based on Observed Time Difference Of Arrival (OTDOA) positioning approach along with the Positioning Reference Signal (PRS), mentioned in Release 9 of LTE technology, to calculate the position of a User Equipment (UE) within a network and performing handover beyond certain threshold boundary. It is shown through simulations that the proposed scheme will reduce the probability of connection dropping, thereby improving performance of whole system. The simulations are performed using LTE tool in MATLAB.
Keywords: Positioning reference signal (PRS), time difference of arrival (TDOA), hyperbola of constant time difference (HoCTD), long term evolution, D2D communication
