Simulation is a scientific method which is largely dominated by computers and has allowed the testing and assessment of many models before actual implementation. The paper proposes an approach to construction of a simulation that models the behaviour of an adaptive queuing protocol (AQP). AQP was developed for database applications on mobile computers in a distributed multidatabase environment but can also be used in many other areas including distributed operating systems. By constructing the simulation model it is possible to both prove that it can be implemented, and at the same time study its expected behaviour in a mobile computing environment. The results of the simulation are analysed and discussed.
