Smart Dust is the network of small devices (also called as Sensor Nodes) with many electronic components such as memory, CPU, radio and sensor and each of these components consumes power. Sensor nodes have a battery and can work only as long as the battery lasts. In other words, it is very important to optimize every computation in order to increase the sensor's lifetime. To achieve this, an energy efficient protocol called as ZigBee protocol is analyzed. Analysis is done using two different topologies (Random and Clustered Topology). Both topologies are properly analyzed in terms of number of nodes and in terms of number of nodes/cluster respectively. Parameters used for analysis are Total Packets Transmitted, Total Packet Loss, Packet Loss Rate and Bit Rate.
