Abstract
Nano-Sensor Networks. i.e., the interconnection of nano-sensors
are expected to expand the capabilities of single nano-sensors by
allowing them to cooperate and share information. Traditional communication
technologies are not suitable for nano-sensor networks mainly due
to the size and power consumption of transceivers, receivers and
other components. The use of molecules, instead of electromagnetic
or acoustic waves, to encode and transmit the information represents
a new communication paradigm that demands novel solutions such as
molecular transceivers, channel models or protocols for nanonetworks.
In
this talk, first the state-of-the-art in nano-sensors, including
architectural aspects, expected features of future nano-sensors,
and current developments are presented for a better understanding
of nano-sensor network scenarios. Moreover, nano-sensor network
features and components are explained and compared with traditional
communication networks. Furthermore, nano-sensor networks for short-range
communication based on calcium signaling and molecular motors as
well as for long-range communication based on pheromones are presented.
Finally, open research challenges, such as the development of network
components, molecular communication theory, and the development
of new architectures and protocols, are presented which need to
be developed in order to pave the way for the development and deployment
of nano-sensor networks within the next couple of decades.

Abstract
Internet users are increasingly using interactive services such
as multimedia messaging, social networks (e.g., facebook, myspace),
sharing (e.g., torrents) and collaborative applications (e.g., wiki
pages). Emerging services (e.g. telemedicine or telepresence) are
also gaining popularity. Simultaneously, Internet users are becoming
more and more mobile, and are growingly interested in maintaining
full access to their services mix while on the go. Together, these
developments are straining current architectures for service delivery
in wireless and mobile networks, which were not designed to handle
large and highly variable information transfer, accommodate dynamic
mobility and employ isolated service management platform. They are
also mostly static and impersonal in their management as they do
not adapt to individual user requirements, habits or surroundings.
In this talk
I address the topic of ubiquitous mobile services from three complementary
directions. The first considers techniques for establishing means
to seamlessly combine different wireless access technologies and
structures, in addition to different service deployment and management
platforms. The second describes design and operation guidelines
of robust and opportunistic networks that can handle the highly
dynamic requirements of future services and their QoS while exploiting
variations in network and medium conditions. The third addresses
support for collaborative and peer-to-peer applications in next
generation wireless environments.
