The manuscript represents wireless sensor networks using numerous topologies of ZigBee. Along with coordinator load, the uses of coordination with such networks were inspected. The investigation has been accomplished via the use of various plots in the OPNET Modeler simulator. The results of the simulation explore the use of coordination with mesh and tree routing to verify the suitability of the topology. It also demonstrates some of the implemented features of the ZigBee protocol and IEEE 802.15.4 MAC specification, using OPNET's ZigBee model suite, like: Mesh routing vs. tree routing, Roaming between Personal Area Network (PANs) & Failure and Recovery procedures. The simulation has been carried out for 20 minutes to investigate the response of routing topologies on the delay, coordinator load and the MAC Load and the data have been collected. The results indicate that the End to End delay, number of hops and MAC load for mesh routing is lower than the tree routing. The results also show that in case of failure and recovery procedures, the simulated networks perform according to the ZigBee Standard.
