  • Essay / Zigbee Scenario Analysis - 1884

    INTRODUCTION: Scenarios and configuration for ZIGBEE: Using the OPNET Zigbee model, some features are implemented such as mesh routing, tree routing, roaming between two PANs and breakdown and recovery. From these features, we have three scenarios: 1. Multiple PAN mobility2. Coordinator failure3. Tree and Mesh Routing Zigbee node configuration can be found using Zigbee settings attributes and simulation attributes. Application traffic is used to find associated traffic generation. The report snapshot times and network training threshold are used for generating the output report. PAN stands for Personal Area Network used to configure the scenarios in this project for Zigbee. We used to assign PAN ID like 1, 2, 3 etc. for the coordinator and let's start the network to begin. MAC is the medium access layer. Using routers, end devices, and coordinators, also called PANs or PAN configurations, we build a network for the scenarios. Now I would like to analyze all these features using Jump to Scenario under the list of OPNET simulator scenarios that are already configured there. The results are in the panels under the DES menu. I created the documentation by going through the readme files under each scenario in which I had learned new information. PART 1-Basic scenarios: 1. Multiple PAN mobility: the aim is to test mobility and also to leave and join the nodes of a network. It consists of three PAN configurations which have different ranges, a mobile_node_1 placed in the PAN-1 configuration, routers and end devices. From the readme file it is clear that the transmit power of each PAN is 2mW and does not overlap. It takes 20 minutes for mobile_node_1 to go from one configuration to a...... middle of paper ......Table: Number of nodes at simulation time 720Finally, in case of coordinator failure, the differences after modification are not clear. The PAN affiliation for coordination failure and spikes and increased number of bits and less loads for PAN 1 than for PAN 2 in MAC load per PAN. There are also minor differences at simulation times 60, 360 and 720. CONCLUSION: In this ZIGBEE network project using OPNET simulator, I observed how PANs work with routers and end devices for different and basic scenarios . Graphs are plotted for all original scenario networks. I also changed the destination of the routers from the original scenario and observed the traces in modified scenarios. So from the graphs it is clear that how end-to-end devices, load (bits/sec) and PAN affiliation changes. We can also observe the traffic received for all PANs at once and the changes in the viewing functions..
