Analysis of topology considerations in indoor ZigBee meshed 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 has been developed in order to analyze interference in a scenario of coexistence of two ZigBee meshed networks which are adjacent one to the other in a particular indoor case. Due to the influence of the indoor environment, topological considerations are relevant in the overall evaluation of the meshed networks. The results aid in modeling the behavior ZigBee systems in arbitrary indoor environments, as well as in adequate planning of large sensor networks based on ZigBee.
