Descripción del proyecto
La urbanización aumenta, al tiempo que lo hacen los problemas de conectividad
Según el Fondo de Población de las Naciones Unidas, el mundo está experimentando la mayor ola de crecimiento urbano de la historia. Más de la mitad de la población mundial, unos 7 800 millones de personas, vive actualmente en pueblos y ciudades; en 2030, esta cifra aumentará unos 5 000 millones. La urbanización requiere un funcionamiento inteligente y eficaz en materia de energía de las ciudades. En este contexto, el equipo del proyecto financiado con fondos europeos MASCOT analizará los posibles problemas que puede plantear la conectividad masiva. En concreto, los caracterizará desde una perspectiva teórica de la información. Los hallazgos de este proyecto, que cuenta con el apoyo de una beca individual de investigación Marie Skłodowska-Curie, se utilizarán para elaborar directrices sobre cómo deben diseñarse los futuros sistemas de comunicación inalámbrica.
Objetivo
It is expected that in the coming decades the population living in urban areas will increase dramatically. Therefore, the sustainability of our planet depends critically on a smart and energy-efficient operation of cities. Wireless communication technologies arise as one of the main enablers to reach this goal. For example, services and applications such as intelligent transportation, industry automation, and mobile healthcare will require to accommodate a vast number of heterogeneous and battery-limited wireless devices connecting asynchronously and sporadically to the network. This is commonly known as the massive connectivity problem. Since traditional wireless communication technologies were not designed to support this kind of services and applications, there is a need for a profound theoretical study of this problem.
The main objective of MASCOT is to characterize, from an information-theoretic perspective, the fundamental limits and tradeoffs of the asynchronous massive connectivity problem. To this end, I will derive in the outgoing phase at MIT nonasymptotic bounds and asymptotic expansions characterizing these limits. In the return phase at Universidad Carlos III de Madrid, I will then explore different strategies to efficiently and accurately compute the nonasymptotic bounds derived at MIT. During the course of the project, I will elaborate guidelines about how future wireless communication schemes must be designed, and I will adapt existing schemes according to these guidelines. The proposed training activities during the fellowship are fundamental for the correct achievements of MASCOT as well as to secure my future career goals.
MASCOT guarantees a two-way transfer of knowledge since it combines my past expertise on elaborating and efficiently evaluating fundamental limits of low-latency wireless communications with the supervisors’ expertise on information theory applied to the massive connectivity problem and asynchronous communications.
