 ===== -- 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.
