A Discrete Event System Model for Simulating Mobile Agent

Simulation has been proved to be a practical approach for performance evaluation of mobile agents. However, the lack of a standard for the execution of mobile agents makes the semantics ambiguous. Thus, the simulation of mobile agents is not feasible or reasonable without an explicitly defined execution model of agents. In this paper, we propose an execution model of mobile agents called SMA. Based on the SMA model, the discrete event models describing the SMA agents and hosts, called SMA-DEVS, are presented using the modelling approach of DEVS and DSDE. We implement a simulation environment based on SMA-DEVS and test the environment with certain mobile agent-based algorithms.
