Simulation and analysis of performance of indoor meshed ZigBee networks

In this paper, system simulation for indoor meshed ZigBee networks is presented. The behavior of the radio channel is evaluated by means of 3D ray tracing algorithms that have been developed in order to analyze interference in a scenario of coexistence of two ZigBee meshed networks which are adjacent one to the other by electromagnetic transparent wall conditions. As a result, coverage plots, EVM values and SNR relations are obtained in the simulation space. The result aid in modeling the behavior ZigBee systems in indoor environments, as well as in adequate planning of large sensor networks based on ZigBee.
