Challenged Networks. Edition No. 1
VDM Publishing House, Oct 2008, Pages: 232
The evolution of wireless devices, such as laptops,
personal digital assistants (PDAs), and cell phones,
has changed the way networking and communication are
perceived. The growing dependence on these devices,
along with the high mobility of users, has increased
the need to be connected in all places at all times.
This increase in user demand, along with the
evolution of new applications such as satellite
networks, sparse mobile networks, and remote
disconnected communities, has ultimately led to the
rise of the delay and disruption tolerant networks
(DTNs) research area.
The future of computer networks includes an Internet
that encompasses numerous heterogeneous networks,
reaches out to the most remote areas, and provides
communication in the most extreme and unstable
conditions. With such a vision, new problems with
large complexities arise. Communication devices in
the future will be required to remain connected
despite the rise of new challenges such as network
partitioning, intermittent connectivity, large
delays, the high cost of infrastructure deployment,
and the absence of an end-to-end path. This book is
an initial attempt to address these challenges.
