With the increasing integration of wireless short-range communication
technologies in mobile devices, novel applications for spontaneous communication,
interaction and collaboration are possible. In this book, we
distinguish between active and passive collaboration. The devices help users
become aware of each other and stimulate face-to-face conversation (active
collaboration). Also, autonomous device communication for sharing information
without user interaction is possible, i.e., devices pass information to
other devices in their vicinity (passive collaboration). Spontaneous communication
of mobile devices leads to so-called opportunistic networks, a new and
promising evolution in mobile ad-hoc networking. They are formed by mobile
devices which communicate with each other while users are in close
proximity.
This book investigates opportunistic networks in their entirety. The proposed
concepts comprise system components, a node architecture, a system model
and a simple one-hop communication paradigm for opportunistic network
applications. One focus of this book is a profile-based data dissemination
mechanism.
Readers of this book would include graduate students and postgraduate
researchers in both academia and industry, who wish to gain a deeper
knowledge of opportunistic networks, its underlying idea and its potential
capabilities.
