Abstract: System simulation is an important way to study the wireless sensor networks.This paper presents a design and implement method of networks simulation system based on MobilityFramework after analyzing and comparing related networks simulation tools.The system adopts layer structure,which can implement the single node layered and define the function behaviors on each layer.In the system,one layer is independent from each other in order to improve the reuse rate of the module code.In addition,it integrates energy-consumption,time-delay,packet-loss models and adopts database as a backstage supporter to strengthen simulation function and capability of storaging and processing experimental data.If providing the configuration file,we can simulate without the platform,which improve the portabillity of simulation examples.Finally,through the simulation experiments,the results show that the system is a good experimental platform for WSNs,which has the feature of modeling fast,effective remodeling,complete function and more reliable experimental data.
