Effective data flow in ZigBee network using OPNET

The ZigBee protocol stack is based on IEEE 802.15.4 which offers a sensible, lucrative solution for low-cost and low power consuming Wireless Personal Area Networks (WPANs). These characteristics make ZigBee network an ideal aspirant for Wireless Sensor Networks(WSN) in many applications such as natural disaster conditions, data gathering for agricultural fields, commercial building and home automation, medical equipment monitoring, industrial control and etc. The latency and dependability are significant performance measurements in sensor networks. This paper focuses on simulating and assessing a Wireless Sensor Network implementing the ZigBee protocol using the Optimized Network Engineering Tool (OPNET)14.5 network simulation tool and evaluating its effectiveness in fixed as well as mobile node network, the determining factors will be end to end delay with respect to network time.
