Stochastic analysis of mobile communication systems (March 1991 - Sept. 1994)

Funded by the Deutsche Forschungsgemeinschaft (German Science Foundation)


An important issue for communication via radio channels is to organize the multiple contention access of a number of mobile stations to a shared medium. Time slots are typically used as a collision resolution method. The analysis and evaluation of such methods contains stochastic elements in three layers.

a) Mobility of the connected stations.

b) Random channel access of stations.

c) The Random behaviour of the radio channel itself originating, e.g., from fading, shadowing, and interference.

The current project aims at analytical models to assess quality, time to full coordination, and the reliabilty of distributed communication algorithms.
