Simulation Study of the IEEE 802.15.4 Standard Low Rate Wireless Personal Area Networks
The IEEE 802.15.4 standard was created in 2003, and its current form results from the modifications introduced three years later. The specification defines the PHYsical layer (PHY), the Medium Access Control sub-layer (MAC), as well as the principle of their interaction with the higher layers. The LR-WPAN are characterized by very low energy consumption, simplicity of their structure making it possible to implement the transmission protocol on 8-bit microcontrollers, as well as low costs of receiving and transmitting equipment. LR-WPAN are designed to be used in different industrial, agricultural and alarm systems, building automatics, monitoring, interactive toys and in particular in Wireless Sensor Networks (WSN).
