ABSTRACT
One of the most famous initiatives consolidating the possible deployment of WSN was the IEEE 802.15.4 [1]. IEEE 802.15.4 offers simple, energy-efficient, and inexpensive solutions to a wide variety of applications in WSNs. IEEE standard 802.15.4 specifies a physical (PHY) and a medium access control (MAC) layer dedicated for a low-rate wireless personal area network (LR-WPAN). e main motivation of IEEE 802.15.4 is to develop a dedicated standard and not to rely on existing technologies, such as Bluetooth or WLAN, and to ensure low-complexity, energyefficient implementations.
