INTRODUCTION: Scenarios and Configuration for ZIGBEE: By using OPNET Zigbee model some of the features are implemented like mesh routing, tree routing, roaming between two PANs and failure & recovery procedures. From these feature we have three scenarios, they are: 1. Multiple PAN Mobility 2. Coordinator Failure 3. Tree and Mesh Routing Configuration of Zigbee nodes can be found using Zigbee parameters attribute and simulation attributes. Application Traffic is used to find related traffic generation. Report snapshot times and Network formation threshold are used for output report generation. PAN means a Personal Area Network which is used to configure the scenarios in this project for Zigbee. We used to assign a PAN ID as 1, 2, 3 etc for the coordinator and starts the network to begin. MAC is the Medium Access Layer. By using Routers, End devices and Coordinators which are also called PANs or PAN configurations we build a network for the scenarios. Now I would like to analyze all these features using Switch to Scenario under Scenarios list in OPNET simulator which are already configured in it. The results are found in Panels under DES menu. I made the documentation by going through the Readme Files under every scenario which I had learn some new information. PART 1-Basic Scenarios: 1. Multiple PAN Mobility: The purpose of this is to test mobility and also leaving & joining the nodes in a network. It consists of three PAN Configurations which have different ranges, a mobile_node_1 placed at PAN configuration-1, routers and end devices. From readme it is clear that the transmit power for each PAN is 2mW which do not overlap with each other. It takes 20 minutes time for mobile_node_1 to switch from one configuration to an... ... middle of paper ... ... Table: Number of nodes at Simulation time 720 Finally in coordinator failure the differences after modification are unclear PAN affiliation for coordination failure and spikes and increase in bits and less loads for PAN 1 than PAN 2 in MAC Load per PAN. Also there are minor differences at simulation times 60, 360 & 720. CONCLUSION: In this project from ZIGBEE Network using OPNET simulator I observed how PANs work along with the routers and end devices for different and basic scenarios. Graphs are plotted for all original scenario networks. I also changed the destination to routers from original scenario and observed the plots under modified scenarios. So that from plots it is clear that how end-to-end devices, load (bits/sec) and PAN affiliation changes. Also we can observe the traffic received for all PANs at a time and changes in visualization functions.
The Unistep IRP Elexol EtherIO 24 Module is a network board that enables multiple devices to connect to an Ethernet network, communicate with each other, and relay information when changes occur. The IRP module is a micro-controller, integrated with many features for interacting with devices connected on a generic local area network; this module was designed to be used in conjunction with other network devices or modules. Some of the applications for the device include industrial automation, digital input and output functions, system monitoring, remote data accessing, controlled machinery, and remote power control.
The Jaagz’ local area network will use category 5 cable and run IEEE 802.3 protocol. Using IEEE 802.3, the network speed will average about 10 Mbps. It will utilize a combination of a star and bus topology, which is the most common topology used in networks. The bus topology makes up the backbone of the network while the star topology branches out.
Enhanced Interior Gateway Routing Protocol is modified in such a way that it lessens the router’s workload and the amount of data that is to be transmitted between the routers. Other than i...
In conclusion, the information covered in this paper shows the different types of security that is associated with each level of the standard OSI model. From the physical layer to the application layer, each layer has a different type of security which must be applied at each layer to prevent any security leaks, spoofing, and infinite loops. These are just a few of the different vulnerabilities that must be protected on a WLAN or LAN.
The Open Systems Interconnection model breaks down host-to-host transmissions into seven different layers where each one performs a specific function. At the same time each layer has the ability to also communicate with adjacent layers in either direction. In essence each layer interacts directly with the layer below it and at the same time also provides support to the layer above it.

This paper will explain several differences between a logical network design and the physical design of a network. Most people tend to think of it as the logical meaning the functional part and the physical as the seeing it part. With saying that one must understand that there is more to the logical and physical design of a network than just the functional and seeing parts. In order for one to understand the differences of how the two operate and work from one to the other, one would need more information than just the functionality and seeing parts. In the following paragraphs of this paper, by trying to outline what makes up the differences between logical and physical design of a network one should then understand his/her purpose.
Sensor-based networks basically are characterized by their continuous mode of operation and power sources, which increases the fault rates in sensors, knowing that maintenance or replacement of sensors is considered expensive.
Many recent advancements which took place in the wireless communications and electronics is the reason which enabled development of cost effective sensors, and those sensors are used for various applications like in household, military and other areas. The networks still have some technical problems which still need to be fixed and are currently being researched.
WLAN (Wireless Local Area network) and its components: The task of developing a WLAN on commercial front possesses a greater challenge. Developing initial design, purchasing and installing components, managing and providing maintenance to the systems are the main basic parts of the WLAN. When we use WLAN on a commercial front then we may face the security and privacy concerns. The total area of that particular commercial area should be accessible. This is only possible with installing huge number of access points. The various components of the WLAN are
In the Figure 2.11, the star network topology is connected to a printer device and a wireless access point device, and acts as the backbone for two branches that connecting 25 PCs in a bus topology. In the star backbone, the devices are not directly connected to each other. For example, if a user wants to print a document, his PC is required t...
technologies such as Bluetooth and ZigBee which are used to carry the information from perception devices to a nearby gateway based on the capabilities of the communicating parties. Internet technologies such as WiFi, 2G, 3G, and 4G carry the information over long distances based on the application. Since applications aim to create smart homes, smart cities, power system monitoring etc.
Modern networking technologies are dramatically making major contributions to our Information Technology industry. Remote systems are acknowledged as a standout amongst the most climbing innovations in today's reality. The cheapest known stand-alone device used for communication is Intercom. Nearly all of your workplaces in addition to houses contain these kinds of convenient products. These plans are mounted for safety purposes so authenticated person easily identified. Nevertheless, very much development is necessary inside these types of technologies along with devices. Most of the exploration, pattern along with setup has been in procedure to the simulation from the automation devices.
IoT network architecture has three layers.First layer is the sensing layer which collects data from different sensing devices. Next is the network layer which transmit and process the information. Different specific IoT applications are supported by the last layer i.e. application layer.
