A location-aided teletraffic measurement scheme for optimizing the locations of fixed relay nodes

Abstract

The optimization of fixed relay nodes' location relies on the demanded teletraffic distribution. However, the conventional measurement scheme conducted at the base station can not provide the demanded teletraffic in a sufficient small area, and the alternative modelling scheme only provides approximated results. Taking the advantage of the emerging technologies including the intelligent mobile terminal, the location navigation technology and the location-based services, we propose a new teletraffic measurement scheme, which employs mobile terminals to collect their own information and then constructs a database recording every mobile terminal's mobility pattern and communication pattern. We exemplify the proposed scheme using simulations, which employs such a database to derive the demanded teletraffic so as to optimize the relay nodes' locations with the purpose of minimizing the total required bandwidth.
