Conferencia: Spectrum Managment in Cognitive Radio Networks

Descripción
Today's wireless networks are characterized by a fixed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% with a high variance in time. The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. This new networking paradigm is referred to as NeXt Generation (xG) networks as well as Dynamic Spectrum Access (DSA) and cognitive radio (CR) networks. Figure 1 shows a general architecture of CR networks.

Conferencia: Wireless Underwater And Underground Sensor Networks

Descripción
Oceanographic data collection, pollution monitoring, offshore exploration, disaster prevention, assisted navigation and tactical surveillance are typical applications for wireless underwater sensor networks. In this talk wireless underwater channel is explored, novel medium access control and routing protocols will be presented. On the other hand, sensor applications in soil media and tunnels have unique communication problems. In particular, the wireless channel pecularities in the underground make communication problems interesting which will be discussed in this talk. Future research challenges will be highlighted in both areas.
