IEEE 802.15.4 is a new standard addressing the needs of low-rate wireless personal area networks or LR-WPAN with a focus on enabling wireless sensor networks. The standard is characterized by maintaining a high level of simplicity, allowing for low cost and low power implementations. It operates primarily in the 2.4GHz ISM band, which makes the technology easily applicable and worldwide available. However, IEEE 802.15.4 is potentially vulnerable to interference by other wireless technologies working in this band such as IEEE 802.11 and Bluetooth. This paper gives a short overview of the IEEE 802.15.4 and carefully analyzes the properties and performance of IEEE 802.15.4 through simulation study and channel measurement. Furthermore, this paper analyzes one of the association scheme named Simple Association Process (SAP) and compares SAP with the original IEEE 802.15.4 protocol. The analytic results are validated via ns-2 simulations.
