Evaluación del rendimiento del Estándar IEEE 802.15.4 (ZIGBEE) en entornos de interferencia.

Abstract

The comparative study of networks Wifi and WSN (ZigBee) evaluated the interference produced between these technologies with the aim of proposing a solution that allows their coexistence. The method that was used in the investigation was the Experimental, which allowed to answer the causes of the problems, that is to say explain what happens the phenomenon of interference and in what conditions it is presented, complementing the investigation with the Chi square technique for the Check Hypothesis The experimental environment was a Wifi network with an access point, two laptops and a network of ZigBee wireless sensors. Measurements use software tools such as hardware and hardware as spectral analyzers. One of the strategies was used in the framework of manipulating the distance between devices, reaching a minimum distance that there is greater interference and vice versa. The results obtained in this simulation environment allowed the interference of the ZigBee technology to affect in a 12.7% a transmission of the information in the networks Wifi, and therefore a decrease in its yield. In conclusion, it was proposed the implementation of a selective microstrip filter that works in a band specific for Wifi eliminating the unwanted emissions, thus allowing the simultaneous operation of these technologies.
