El telèfon, que es va desenvolupar exclusivament per a transmetre veu, avui s¿utilitza, en molts casos, per a connectar ordinadors entre si. Des de llavors han aparegut les xarxes locals, les connexions de dades a llarga distància amb enllaços transoceànics o satèl ·lits, la telefonia mòbil, etc. Mereix una menció especial la xarxa Internet dins d¿aquest món de les comunicacions a distància.

The case of Wireless Multimedia Sensor Networks present additional features such as the fact of transmitting multimedia rich data or the fact of having directional sensing areas. This paper presents a scheduling scheme for clustered nodes according to overlapped Field of View (FoV) regions. This approach schedules nodes applying

Sensing and communications consume energy particularly in wireless multimedia sensor networks (WMSN) due to huge amount of data generated by the multimedia sensors. Therefore, judicious power management and sensor scheduling can effectively extend network lifetime. In this paper we consider the problem of scheduling multimedia sensor activities to

In the last years, it also has been applied to networking paradigms such as social networks, virus spreading in Internet and lastly to opportunistic networking in mobile networks. In this paper we revise some of the facts of epidemic modeling in mobile networks and use

Given that outbreaks of vehicular computer worms self-propagating through V2V links could pose a significant threat to road traffic safety, it is important to understand the dynamics of such epidemics and to prepare adequate countermeasures. In this paper we perform a comprehensive characterization of the infection process of variously behaving vehicular worms on a road traffic scenario of unprecedented scale and heterogeneity. We then propose a simple yet effective data-driven model of the worm epidemics, and we show how it can be leveraged for smart patching infected vehicles through the cellular network in presence of a vehicular worm outbreak.
