Tomorrow´s society will see hosts of people
constantly on the move, commuting between
home and work, meeting up with family and
friends or visiting shopping centers and leisure
facilities. While on their way, these people use
mobile devices to connect to the Internet, utilizing
journey time for work-related tasks, entertainment,
or socializing in online communities.
Current fourth generation cellular networks are,
however, not designed to efficiently serve large
numbers of comparatively high-mobility users,
often causing insufficient service quality while
on the move. Machine-type communication will
cause further aggravation, with wirelessly connected
sensors that constantly monitor/record
our environment, and vehicles that autonomously
exchange traffic- and safety-relevant information.
In this article, we highlight challenges that must
be addressed by future mobile communications
to enable efficient support of large numbers of
highly mobile users in networks that are crowded
with quasi-static (nomadic) users. We survey
existing solutions and put special emphasis on
open issues and competing priorities.
