An approach to use FB-AODV with Android

This work talks about an attempt to create a Mobile Ad-hoc NETwork with Android smartphones. We used FBaodv to manage the networks and some bash script to share informations within the networks. MANET was tested by simple applications to view local neighbors, to send sms over the networks.

Game-based learning and Gamification to promote engagement and motivation in medical learning contexts

Smart learning environments can be defined as systems aimed at proposing innovative uses of emerging pedagogical approaches and technologies to support effective learning experiences. In the past years, rather than designing and developing even more advanced technological solutions attention has been focused on defining environments that adopt appropriate strategies to sustain student motivation and engagement. Game-based learning and gamification approaches could be a promising solution, since there is much experimental evidence that proves their effect. In this context, our research aims at defining and developing a Smart Learning Environment able to improve engagement and motivation by means of game-based learning and gamification approaches. In particular, the paper presents two serious games that, using the gamification dimensions, aim at sustaining engagement and motivation in learning processes in medical contexts. In particular, the games involve both the patients, who have to acquire knowledge and skills about their disease, in order to become responsible for their choices, and the medical and paramedical staff, who must acquire knowledge and skills about diagnostic procedures, therapeutic interventions and follow-up of patients. Some results of a user test show that the games enhance student motivation and this means improvement also in knowledge acquisition.

Hixosfs for Ubiquitous Commerce through Bluetooth

Hixosfs is a Linux filesystem designed to easily cataloging and retriving files according final user selected metadata. The idea is the use of bluetooth technology to create an ad-hoc indoor network managed by hixosfs. The system has been implemented using embedded systems linked to each other using bluetooth connection or an ad-hoc wireless network. In each of these, a hixosfs filesystem based database has been used to improve the performance.

An Embedded Filesystem for Mobile and Ubiquitous Multimedia

Bluetooth proximity marketing is a relatively new marketing solution not widely spread yet. Our purpose is to create a layer by an ad-hoc file system (hixosfs) and a platform independent language (Python) to facilitate the modeling of the system and to make possible the efficient use of the embedded devices in bluetooth marketing. Our idea has been tested in two real contexts. We compared the idea with the standard approach and we noticed how the approach is more performant.

Hixosfs_Music: A Filesystem in Linux Kernel Space for Musical Files

Hixosfs_music is a Linux ¿le system that could be included in the standard Linux kernel. Differences respect to the widely used ext2 ¿le system are additional features for storing and ef¿ciently retrieving musical data. Specially it extends the inode for each musical ¿le with new proprieties relatives to the ¿le content such as album, author, title, year. Beside standard user mode tools (stats, chmod, ls and so on), speci¿c command are needed to directly handle with new ¿le tags (statmusic, chmusic, orderby, and so on).

HSFS: A Compress Filesystem for Metadata Files

In this paper we propose a solution to improve the search among compress data. A Linux filesystem have been implemented by combining the advantages of squashfs (compression) and hixosfs (for research). We test our idea with DICOM file used to store medical images.

An Embedded Solution for Managing an Ad-hoc Wireless Network

In this paper we propose a layer for managing an ad-hoc network in order to improve the efficiency of the embedded devices in blue tooth marketing. The infrastructure is realized by an ad-hoc file system (hixosfs) and a platform indipendent language (Python). We present the results of two tests conducted in laboratory and in a cinema.

IFHNFS: fast indexing information in mobile devices

Abstract To track movements of objects and people we need to use expensive technologies and complex softwares. Usually these softwares need lots of memory. There are many examples of objects and people of which would be useful to know the precise locations. Something sent via pony express, position of buses in the city, friends’ locations, and so on. Our purpose is to use connectivity of smartphone to share position via gps by using only a filesystem created ad hoc without databases or user space programs. IFHNFS is based on Hixosfs and NFS (Linux kernel). Indexing the most relevant data directly in the fs structure makes the exchange of data Faster and, via NFS, potentially available whenever and whenever. Ad-hoc solutions for Android have been developed in real contexts. The system have been tested on a network of Android OS devices that share data with a Linux server.

File Metadata Management in Embedded Linux

In embedded Linux systems low power consumption and memory usage are strict constraint. The problem to manage a large quantity of file metadata, that usually represents the most expensive task of such systems, is a task delegated to user space programs, generally, database based. In this work we propose how to deal with metadata at file system level with Hixosfs. Hixosfs is an ext2 based Linux filesystem, designed to easily cataloging and retrieving e-mails, musical files and logs files according final user selected metadata. The core idea is to move the problem complexity from userspace to kernel level to speed up the overall process. The implementation mainly required ext2 file system structure to be extended to store file tags, then they can be accessed and modified directly by system calls. Analysis and comparison works state this approach to be suitable for a large amount of data.
