PhD Thesis

Title: Contribution to provide QoS over Mobile Ad Hoc Networks for Video-Streaming Services based on Adaptive Cross-Layer Architecture. Download Thesis in PDF format

Qualification: Cum Laude.

Advisor:  Mónica Aguilar Igartua.

Description: The main objective of this thesis has been to develop new techniques, and to combine existing ones to improve the performance of multimedia services over wireless IEEE 802.11x Ad Hoc networks, focusing on the provision of video-streaming services over MANETs. Aspects such as multipath routing, network state monitoring, video characteristics, path classification, dynamic self-configuration, life-time of the routes, trust and reliability of the nodes within the forwarding paths, among others aspects have been tackled.

Awards: UPC Research Grant (4 years).

Projects: Collaboration in national and international R&D projects: SECONNET, ITACA, ARPA.

Contributions: Thesis code contributions can be downloaded from here .

Publications: International conferences were held as well as articles for journal publications indexed in the JCR database. They are available at the publications section.

Professional Experience

GTD Security Systems 2009 - Present

Software Engineer

Project and Software Engineer at GTD Aeronautical and Defense and GTD Security Systems. Currently involved in projects using different technologies (C++, Qt, OpenGL, Linux & Windows).

  • ALICIA: All Condition Operations and Innovative Cockpit Infrastructure is a European R&D research project to extend operations of aircrafts in degraded conditions. Currently designing and developing different modules of the proposed system architecture, such as propose automatically new flight plans to the pilot to avoid weather conflicts. These new flight plans have been computed using Voronoi diagrams and graph theory.
  • WiMax: projects where WiMax technology has been used to transport Internet signal to places where there is no Internet coverage using Point to Point stations. Also, other projects have been managed where standard WiMax installations using Access Points have been used to transport video flows.
  • Onboard Communications System: this project involve the communication using different technologies (3G/GPRS, Wifi and mainly TETRA) of all the police cars (2500+) of the regional police corps of Catalonia (Mossos d'Esquadra) with the central stations, so as they are able to do management tasks online when an incident occurs.
  • iPen: a digital pen capable of recognise handwriting characters using Anoto and Vision Objects technology. I have been involved in the development of the software solution. It uses Bluetooth technology to transfer the information, through a PC or a mobile. 95% of recognition accuracy for both upper and lower handwriting text. Currently the systems is being implanted in hospitals, City Councils and police corps. Some projects involve more than 1.500 iPens.
  • Video over IP: installations using Video over IP have been implanted. I have obtained certification from Genetec as installer and configurator of its video over IP security managing software Omnicast.

Telematic Services Group (UPC) 2005 - 2009

R&D Engineer

  • Four year period at the Technical University of Catalonia as a fulltime researcher at the Telematics Department in the TELECOM BCN School in Barcelona, obtaining the degree of Doctor of Philosophy in Telecommunications Engineering enfasized on Telematics.
  • I have been working in the design and implementation of a routing protocol specific for video-streaming services over wireless Ad Hoc IEEE 802.11 networks (ammendments .11b and .11e).
  • Real and simulated multimedia platforms have been designed and implemented. The open source ns-2 simulator has been used over Linux. Various modules for the simulator have been developed, published and included into it. They are available to download here.
  • QoS (Quality of Service) patterns have been given to the applications developed as well as to the routing protocol. Scripts have been implemented to monitorize in real time the user perceived video quality (PSNR).
  • Main working issues: Video-streaming services and Unix platforms.
  • Several studies and publications have been done along these years for national and international Congress and Conferences. Works were presented through conferences in the country where the Congress took place. Also, high impact factor journals have been published, indexed in the JCR database.
