This paper presents the procedure of tuning and simulation of an adaptive predictive control strategy to control the longitudinal and latero-directional movements of a unmanned aerial vehicle (UAV), using the Matlab ® - Simulink® platform. Uses the mathematical model of a UAV which are initially performed simulations of the system in open loop, identification is carried on online, and predictive control and PID controllers algorithms are implemented with the parameters obtained, to control the angle of pitch, roll and yaw. Control strategies used presented a good performance and manage to stabilize the aircraft properly. Finally, they are presented and analyzed the results of the performance of the system with predictive control and PID control using metrics of the integral of the error and of the work of the manipulated variable.

In this paper we present the research results that conducted to address the problem of associating a user to a wireless access point (AP) in a multicell 802.11 network in which service a large number of users, each user selfishly is connected to the access point that allows it to guarantee a minimum data transfer rate, determined arbitrarily by the user required service. To do this, the interactions are modeled on the wireless network as a non-cooperative game, then the satisfaction equilibrium concept (SE) is introduced and the algorithm to solve the problem of association under this concept is proposed; finally we illustrate the simulation results obtained in a network scenario where, for simplicity and without loss of generality two users and two access points are assumed.
