In this paper, the authors explain about the characteristics of IEEE 802.15.4 protocol stack. A hybrid topology has been design by using three possible combinations of Zigbee network topologies considered in different scenarios to verify the consistency of this communication network. The scenario has been design under the consideration of device failure in hybrid topologies. There are various parameters like throughput, delay, network load and number hops are measured during these scenarios. The result concludes that star-tree hybrid topology is better to make an effective network in case of device malfunctioning.
