The IEEE 802.15.4 network standard is being used as a suitable solution for wireless sensor networks in many environments and areas of expertise. They differ from other types of wireless networks because of its specific features. This work intends to analyse the mobility impact on IEEE 802.15.4 networks. For this reason it was developed a simulation platform with the requirements necessary to evaluate and compare environments with and without mobility. The results show that the mobility of elements in the scenarios evaluated caused signal degradation at short distances, but improvement in the rate of transmission for distances between 30 and 40 meters, as well as at distances greater than 60 meters. This is due to the fact that at intermediate distances the network presents high rate of collisions, making the technique CSMA/CA improve network performance in environments with more variability of the signal.
