Grids accesibles

El uso de los dispositivos móviles ha aumentado de forma importante alrededor del mundo en los últimos años. Por otro lado, las capacidades actuales de los teléfonos inteligentes se han incrementado de tal forma que comienzan a ser considerados como una posible infraestructura de cómputo. Por ejemplo, se ha estudiado la problemática de incorporarlos a una Grid, no sólo para mejorar el acceso de los usuarios a los recursos de la Grid, sino como proveedores de recursos; en este último caso se conocen como Grid Móviles o también Grids Accesibles. Este trabajo profundiza sobre el estado actual de la tecnología existente para Grids Móviles y se busca el sistema más adecuado que permita la ejecución de tareas, escritas en C++, en dispositivos móviles. Como resultado del análisis se decide desplegar la Grid BOINC, la cual permite ejecutar tareas en C++. Entre las principales conclusiones de este trabajo se encuentran, el confirmar la posibilidad de ejecutar tareas en C++ en teléfonos Android, realizando ciertas modificaciones a los programas, por otro lado se nota una tecnología aún en estado de maduración, por los pocos trabajos prácticos encontrados.This Graduation Project presents a comparative analysis between different projects implementing Accessible Grids that use mobile devices. As a result of said analysis the author decide on deploying the BOINC system, including mobile devices, in order to execute assignments. BOINC offers some limitations, like the need for a central manager and lack of control on the resources. Due to BOINC’s implementation of voluntary computing there’s access to more resources, but the availability of said resources depends on the users. Although the technology still in development, due to the few practical Works found.Ingeniero (a) de SistemasPregrad

Mitigating reply implosions in query-based service discovery protocols for mobile wireless ad hoc networks

Abstract. Providing service discovery in an efficient and scalable way in ad hoc networks is a challenging problem, in particular for multihop scenarios, due to the large number of potential participant nodes and the scarce resources in these networks. In this paper, we propose and evaluate an approach to mitigate the reply implosion problem in querybased service discovery protocols for multihop mobile ad hoc networks. Our simulation results show the scalability and efficiency of the proposed solution. We demonstrate that the proposed scheme considerably reduces the number of transmissions without compromising the efficiency of the service discovery in scenarios of pedestrian mobility.

Naval Research Program 2019 Annual Report

NPS NRP Annual ReportThe Naval Postgraduate School (NPS) Naval Research Program (NRP) is funded by the Chief of Naval Operations and supports research projects for the Navy and Marine Corps. The NPS NRP serves as a launch-point for new initiatives which posture naval forces to meet current and future operational warfighter challenges. NRP research projects are led by individual research teams that conduct research and through which NPS expertise is developed and maintained. The primary mechanism for obtaining NPS NRP support is through participation at NPS Naval Research Working Group (NRWG) meetings that bring together fleet topic sponsors, NPS faculty members, and students to discuss potential research topics and initiatives.Chief of Naval Operations (CNO)This research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.
