Abstract: The main advantage of wireless networks is the flexibility provided by non-existence of cables. However, the presence of perturbations in the medium may create temporary partitions (called inaccessibility periods) in the network, an undesirable phenomenon for time-critical communications. In this way, this paper presents the importance of knowledge of inaccessibility for supplying an effective and complete real-time communication support. The IEEE 802.15.4 specification was used in our analysis for showing the main problems caused by the occurrence of inaccessibility scenarios when their existence are unknown, presenting the impact of this scenarios in the network temporal behaviour.
