Recently we could observe a huge change in the mobile industry when the original idea of mobile phone was
transformed into the new concept of mobile multimedia devices capable to perform multiple complex tasks and
integrating a number of functionalities. As a consequence it resulted in significant increase of the device integration time
and cost and complicated deployment of the new technologies. The device integrators are forced to favor modularity
everywhere where it is possible in design of new devices, which results in a new trend towards networked architectures
for the mobile devices.
However, moving towards networked architectures specifically designed to overcome limitations brought by the mobile
devices is a time consuming task. It requires fresh mind analysis of many solutions applied in other contexts, since some
of the constraints and requirements are unique in comparison with e.g. SoC, NoC, which are the most known embedded
network solutions, and of course they are significantly different comparing to the wide area networks. The main
differentiating factors are: strongly constrained power consumption by the battery life time; and a need for modular
architecture to allow reuse of the existing components or modules.
The paper provides an overview of the state of art in the embedded networks research and describes general background
for our studies, key assumptions, restrictions and limitations that we faced at the beginning of development of the
embedded networks architecture for mobile devices.
