Comparitive analysis of different modes of operation for Zigbee mac with variation in network size and traffic

In this paper we have presented a brief review of ZigBee technology, the factors that led to its development and the subsequent versions that evolved. This paper presents and briefs different modes of operation for ZigBee devices and the different layers of ZigBee with emphasis on the operation of MAC layer. The Zigbee devices can operate in either beacon or non-beacon mode. We analysed and compared throughput and energy consumption of these operational modes with respect to varying network size and number of packets transmitted.
