The IEEE 802.15.4 protocol has become the primary solution for many Low-Rate Wireless Personal Area Network (LR-WPAN) applications. This is especially the case for industrial sensor network applications such as automation control. The authors contribute to the better understanding of the protocol behavior by presenting a set of results of simulation experiments. The results outline the capabilities of this protocol in the selected scenarios but also the limitations. In particular, they investigated the dependency of the protocol on protocol-inherent parameters such as the beacon order and the superframe order but also to different traffic load. The results can be used for planning and deploying IEEE 802.15.4- based sensor networks with specific performance demands.
