A Study of ZigBee Network Topologies for Wireless Sensor Network with One Coordinator and Multiple Coordinators


Wireless Sensor Networks have become a cheap and viable solution for a variety of applications, including monitoring of critical infrastructure (water supplies, power grids, traffic networks, agriculture, telecommunications systems etc.), wildlife habitat monitoring, industrial quality control, disaster recovery situations, military applications and much more. The ZigBee network model is more suitable for battery capacity, bandwidth and computing power’s limitations of WSN. In the present investigation, the modeled system was simulated using OPNET Modeler v14 to obtain the results in order to study the performance of the system in terms of tree routing, mesh routing, multiple coordinator system and if one of the coordinators was failed. The results showed that tree routing was more suitable for WSN than the mesh routing and mobility of end device was better in multiple coordinator system.
