Study on the performance of beacon-enabled ZigBee networks based on OPNET simulation

Aiming at understanding how the superframe parameters impact the performance of ZigBee networks, we study the impact relationship based on the OPNET modeler and conduct simulations on network models with different superframe parameters.On the basis of the simulation results,we identify the interrelation between network performance and superframe parameters.Furthermore,based on the identified interrelation,we propose a configuration strategy of superframe parameters for ZigBee networks. Experimental results show that the impact of the superframe parameters on the performance of ZigBee networks is depicted more comprehensively by using the OPNET simulation method, and the proposed configuration strategy provides a better configuration of superframe parameters for ZigBee network applications.Key words:
