Wireless Sensor Networks (WSNs) are an emerging field of engineering with various applications. IEEE 802.15.4 is the basis for the ZigBee enabled WSNs. The IEEE 802.15.4 standard is adopted as a communication protocol for Low Rate Wireless Personal Area Networks (LR-WPAN) which supports low data rate, low power consumption and short transmission distance. The IEEE 802.15.4 standard specifies the PHYsical (PHY) and Medium Access Control (MAC) layers and the ZigBee specifies the network and application layers in the IEEE 802.15.4 based WSNs.
