Support for heterogeneous dynamic network environments through a reconfigurable network service platform

In a future internet of things, an increasing number of every-day objects will be connected with each other. These objects can be very diverse in terms of their network protocols and communication technologies. As more resource constrained devices such as sensor networks and PDAs are added to our environment, supporting efficient communication between these heterogeneous devices becomes a key challenge in next-generation networks. To realize this challenge, this paper presents a reconfigurable network framework (IDRA) that supports direct connectivity between heterogeneous co-located devices, without the need for complex translation gateways

Desarrollo de un sistema embebido móvil de bajo costo utilizando la tarjeta beaglebone black y programas de código abierto

El presente trabajo describe la implementación del sistema operativo libre Android, sobre una tarjeta embebida de bajo costo llamada Beaglebone Black. El objetivo es desarrollar un sistema embebido, que funcione de plataforma para probar aplicaciones móviles, interfaces gráficas, controladores de dispositivos, entre otros proyectos que se están llevando a cabo en la facultad de ingeniería. Se presenta las funcionalidades dela capa de interface de radio (RIL), y cómo se puede configurar en el sistema operativo. Se explica también como manejar el modem GSM Enabler III de Enfora, a través del RIL y la interface serial. Finalmente se presentan los resultados obtenidos, que fueron la posibilidad de hacer llamadas y enviar mensajes de texto a través del sistema, haciendo uso de los programas desarrollados en la facultad para sistemas Android.Palabras Claves: Android, beaglebone, código abierto, ril, sistemas embebidos

A scalable low-power WSAN solution for large-scale building automation

Nowadays, wireless sensor and actuator networks are a hot issue because they can enable the Internet of Things at little expense. Research activities mainly focus on one aspect of these networks (e.g. energy consumption) neglecting others (e.g. latency, scalability). Aspects like energy reduction, scalability, Quality of Service, and reliability are key requirements in our envisaged heterogeneous applications for sensor and actuator networks in commercial/residential buildings consisting of 1000+ nodes. In this paper, a stack which meets these requirements is proposed. We found that simulations only are not sufficient when developing WSAN solutions. We showed that it is possible to combine low power with low latency on large scale QoS aware networks
