PhD Fellow On Wireless Sensor Networks (Thesis title: Experimental Evaluation of the PHY layer of WSN focused on Smart City applications)- 2011-2013
The goal of my PhD is to provide solutions by using propagation models obtained in real applications in order to increase as maximum as possible the communication distance considering the required modulation, data rate, packet size and frequency as constraints, and more importantly the energy consumption of the node. Solutions included antenna miniaturization (the use of SMD antennas) and additional RF Front Ends outside the transceiver. Both solutions, as well as correct placements for repeaters and ground nodes were crucial for the proper operation of the network in the real scenarios, and they had to be validated with measurements in scenarios quite similar to the real ones.
MASTER IN DESIGN OF TELECOMMUNICATION SYSTEMS – 2010-2011
The Master thesis was carried out with the company WorldSensing to evaluate localization techniques for the current FastPark product. A theoretical and practical development of localization algorithms based on Wireless Sensor Networks from a set of Anchor Nodes was realized. The theoretical part involved the design of a simulator based in Matlab where several tracking algorithms were compared: Kalman filter, extended Kalman filter and Interacting Multiple Model Estimator in a quasi real scenario. The practical scenario consisted to develop a small Java based navigator. A testbed was carried on from a set of 24 sensors deployed on the field. The results and knowledge obtained in this thesis was improved in the 3-years doctoral grant.

ELECTRICAL AND ELECTRONICS ENGINEERING – 2006-2008
At Universitat Autònoma de Barcelona (UAB)-spcomnav:
This degree provided knowledge of antennas, RF microwave circuits design, wireless communication aspects, analog and digital electronics and digital signal processing for wireless communications.
This thesis consisted to obtain large scale models for WiMAX based over the IEEE 802.16-2004 standard operating at 3.5 GHz in different scenarios of the university campus. Firstly it realized a general introduction to the WiMAX as one of the considered BWA (Broadband Wireless technology) and then it defined the employed equipment. Subsequently it began to analyze the WiMAX coverage at different environments: indoor and outdoor with the aim to extract simplified empirical channel models (path loss) using the measurements obtained by WiMAX CPE terminals. Finally it introduced the InterRural project of the Spain’s Ministry of Industry realized between October 2007-March 2008 with other collaborator companies such as Telefonica, Hispasat, Gigle and Iber-X. The aim of InteRural’s project was to compare different wireless broadband access technologies like WiMAX and WiFI 802.11a as WLL (Wireless Local Loop) alternatives. Both technologies were put in practice in two scenarios: LOS and NLOS just for comparison. Part of this work was published in the XXIII Simposium Nacional de la Unión Científica Internacional de Radio. “InterRural: Internet Rural mediante Redes Heterogeneas e Itinerantes”.

BACHELOR SCIENCE OF COMPUTER NETWORKS, INTERNET AND SERVICES-2002 to 2006
At both Universitat Politència de Catalunya (UPC) and North Wales Institute of Higher Education
The bachelor thesis consisted in developing and evaluating a high security WiFi network based on client-server mutual authentication. In particular a IEEE 802.1X-EAP-TLS using RADIUS as the authentication server. This security scheme is known as WPA-Enterprise. The approach of using encrypted certificates to authenticate users is more secure than using passwords.
Meanwhile, in the last year 2005-2006, a 2nd degree was obtained at North Wales Institute of Higher Education from United Kingdom, by means of a 9-months ERASMUS program.
