A new stochastic spatio-temporal propagation model (SSTPM) for mobile communications with antenna arrays [PDF]
In order to evaluate the performance of third-generation mobile communication systems, radio channel models are required. The models should be capable of handling nonstationary scenarios with dynamic evolution of multipath. In this context and due to the

Improved Community Network Node Design using a DLEP based Radio-to-Router Interface [PDF]
Using a static link state routing metric in wireless mesh and mobile ad hoc networks without major efforts in optimizing the physical link properties has proven to be inefficient. It does not take into account link quality information.
