The IEEE 802.15.4 and ZigBee protocol stack offers a practical application solution for low cost, low data rate, and low energy consumption characteristics for Wireless Sensor Networks (WSN). The ZigBee networks facilitate many applications, such as commercial building and home automation, security, healthcare medical monitoring, vehicle monitoring, agriculture and environmental monitoring and so on. Energy consumption, latency and reliability are critical performance measurements in most monitoring systems. This paper focuses on simulation an IEEE 802.15.4 and ZigBee protocol using the OPNET simulator.
