Queueing Networks and Flow Control
Queueing networks are established in many disciplines and queuing theory in combination with control and information theory is an extremely useful tool. In wireless systems queueing of data not only has the effect of using opportunistic transmission schemes but has particular design and theoretical effect.

Coordination, Cooperation and Control in Wireless Networks
The next step in (cellular, mesh, ad hoc) networks is to break the interference barrier. Future systems will afford that schemes are run by suitable control and self-organizing mechanisms without any help of the operator.

Generalized Multicarrier Transmission
Nowadays, multicarrier systems such as LTE/LTE-A evolve more and more towards intercell cooperation and coordination. However, neither of the theoretically possible huge performance gains could be realized yet due to practical impairments such as asynchronism and channel uncertainty. One of the key solutions is the use of Generalized Multicarrier Systems.

Wireless Sensor Networks
A wireless sensor network is a collection of sensor nodes which are capable to capture different physical phenomena, and/or of acting on the environment. The main difference to a collection of wired sensor nodes is the ability to process and communicate the gathered information in a wireless fashion ... More...
