IEEE 802.15.4 is an emerging standard specifically designed for Low-Rate Wireless Personal Area Networks (LR-WPAN) with a focus on enabling the Wireless Sensor Networks. It attempts to provide a low data rate, low power, and low cost wireless networking on the device-level communication. This paper provides a brief description of Zigbee standards including different topologies it supports. It focuses on developing different topology models for the Zigbee standard using AODV protocol and the performance evaluation of these models using different traffic. Several simulations have been carried out at frequency of 2.4GHz with data rate of 250kbps. The performance differentials are analyzed using various metrics like packet delivery ratio, end to end delay, jitter and load factor are simulated using NS2. The paper describes all the parameters used for the simulations in detail and then compares each traffic model with topology. Based on the study we have drawn inferences and concluded star topology gives 100% packet delivery ratio in CBR and Poisson traffic, whereas tree topology also gives 95% of packet delivery with same traffic, but mesh topology has high load factor. In Poisson traffic mesh topology gives 98% of packet delivery.
