Wireless sensor network (WSN) is a set of sensing devices that communicate with each other via a wireless medium. These sensing devices capture the sensed data, process it and send it to the main station which is called the Base Station (BS). Most of WSN applications are designed to transmit with low data rate, low energy consumption and at low costs. Zigbee is a new wireless protocol governed by the IEEE 802.15.4 standard; it is a technology of data transfer in wireless sensor networks. It is characterized with low energy consumption and it is designed for multi tunnel control systems. In this paper, a grid network topology is implemented according to 802.15.4/ZigBee standard using QualNet Simulator 5.2. By tryingdifferent Beacon Order (BO) and Superframe Order (SO) combinations, this paper aims to find the optimal Personal Area Network Coordinator (PANc) placement in grid topology based on energy consumption, end to end delay, and throughput. However, this paper proved that when PANc is placed at any angle of grid topology, then the maximum throughput is achieved, while when the PANc is placed at the center of grid topology, then the minimum energy consumption and end to end delay are achieved.
