In this paper we introduce NIESIM (Network Information Economics
SIMulation), a software for simulating a mobile communications scenario
and studying the value of information in the context of mobile network
management. The modelling principles and the simulation strategy used to
design and develop NIESIM software are introduced, along with
simulation results. We consider an application of NIESIM to support the
definition of the grade of service in a network that is exposed to
failures. An exploratory discussion of the findings and their
implications to future work is also presented.
