 ===== -- Scientific Work =====
-We use the antenna positions generated by the scripts in our work entitled ''Joint Power-Delay Minimization in 4G Wireless Networks'' (Farah Moety, Samer Lahoud, Bernard Cousin, Kinda Khawam), published in the proceedings of the Wireless Days conference (WD'14) in 2014. We study the case of a realistic Long Term Evolution (LTE) Network where the challenge is the high computational complexity necessary to obtain the optimal solution. Therefore, we propose a simulated annealing based heuristic algorithm for the power-delay minimization problem. The proposed heuristic aims to compute the transmit power level of the network BSs and associate users with these BSs in a way that jointly minimizes the total network power and the total network delay.

The objective is to jointly minimise the total network power and the total network delay. In the following figure, we show the coverage area of each BS when transmitting at the lowest power level and the user distribution in the studied area.

+The automation tool can be used in different scenarios. For instance, in order to illustrate the densification of the network deployment, a comparative study can be performed on the 2G, 3G, and 4G networks. The case of the city of Rennes is presented hereafter.
