Today, our everyday life is almost impossible to detach
from the influence of wireless mobile communication
technologies. This global trend is growing exponentially, and
the mobile-only data traffic is expected to exceed stationary
data traffic. However, for further development of mobile
communication, there is a major obstacle to overcome, which
is the resource-paucity of portable devices relative to
stationary hardware.
