WSN is a wireless sensor network that is widely used for many purposes example Weather detection, Fire detection, Temperature sensor, Device tracking, and so on. We are using this kind of wireless application in our daily routine. In recent times, we are developing lots of projects based on wireless sensor networks. It is one of the emerging technologies right now. But, we don’t know how these kinds of technologies have been constructed, how it’s working. This is important to have a basic knowledge of modern technologies. This article is very useful for gaining your idea about TOSSIM in WSN and also give a piece of knowledge in topology, gateway, and characteristics of Wireless Sensor Network and so on.
TOSSIM is abbreviated from TinyOS sensor network and it’s mainly designed for the discrete event simulator. If we need to compile TinyOS application, TOSSIM framework is best for that kind of compilation in personal computers. It gives permission to the user for the repeatable and controlled environment for debugging, analyzing, and testing the application.
It is represented as a TinyOS wireless sensor network to simulate the discrete event in the distributed system. From the concept of network simulator version 2, TOSSIM is built based on NS2 Simulator. Due to this, the attraction and behavior of the network are based on the granularity of bits and do not base on the packet level. Here, the sensor networks are called motes.
This is the basic concept of TOSSIM in WSN. The overall concept of TOSSIM is to simulate the TinyOS application for discrete events. Then the following topics will go through what is TinyOS event-driven, the reason for using TinyOS, aspects, and suitable sensors for TinyOS. Let we will separately see each topic.
In this TinyOS, the components are connected by wire to construct a program. The reason we said event-driven is this OS has built-in functions, if in this situation the function is needed and use a function itself by using nesClanguage command. It is also has a scheduler it is used to connect components that are represented by the graphical structure.
The main reason for using TinyOS is its flexibility and one of the main goals of TinyOS is to accelerate and enable innovative ideas.
Aspects of TinyOS: This OS supports packet storage, communication, actuation, routing, and sensing because of common interfaces and components.
TinyOS gives support for a number of hardware problems and is also used in various sensor motes for a generation. Event-driven is a perfect sensor for TinyOS because its communication and computation tight coupling is used to select sensors in a particular domain.
The main purpose of the sensor network is to monitor the environmental and physical condition in various places with the use of distributed autonomous sensors it contains some types of parameters there are vibration, Temperature, Sound, Pressure, motion.
So far, we discuss TOSSIM in WSN and the basics of TinyOS. Then we will move on to the next topic which is a topology in Wireless Sensor Networks. Topology is nothing but denotes the structure of the network. Let’s see what are the structures used in a wireless sensor network.
The above content insists on the basic structure of the wireless sensor network. Then we move on to the other topics there are deployment and ways to deploy the nodes in wireless sensor networks.
Here, more number sensor nodes are connected with each other to monitor the one region and then the main duty of the wireless sensor network is to get the data from the end devices and process that received data then transmit the data to the current location.
Here, sensor nodes are deployed using some scenarios at it can be classified into some ways. This kind of deployment method are moreover same as a particular application and it has two ways to deploy the sensor nodes that are,
The above two topics give a clear idea about a deployment in WSN and also deploying steps to deploy the sensor nodes. Then we will discuss gateway. Consider some Wireless Sensor Network applications that are must communicate with WAN or LAN (Wide Area Network or Local Ares Network) via a gateway.
Gateway is an intermediate node between wireless sensors networks to the other network for transmitting signals are information’s from one network to the other network. Assume the currently located server that is mainly stored the data and processes adding some resources to the device.
This is the actual explanation of gateway in a wireless sensor network. Mainly, the gateway acts as a bridge between two kinds of networks. Then we will discuss some characteristics of the wireless sensor network.
These are the characteristics that are calculated from the simulation result of the wireless sensor network. The next topic we will see about a demo of TOSSIM in WSN.
This kind of TOSSIM simulator is based on the solution of distributed computation and fully parallel to give the solution for the MIS problem (Maximum Independent Set) using of Hopfield neural network with hardware platforms on wireless sensor networks.
Here, we will see about the objective or aim of TOSSIM and also the virtual location interface. Also, we note the important method that is called FakeLocation. Then we will go through the next section that contains the information about performance and metrics of simulation.
High mote count sensors are a must that needs to simulate with environmental real-time applications. These are some of the performance metrics of TOSSIM. Then we deal with the topic that is Visualization. Here TinyViz software is used it is also the same as a java visualization and it acts as an actuator for TOSSIM.
The above section has the basic concept of TinyViz that is visualization software. Finally, we will discuss the advantages of wireless Sensor Networks.
So the above list is the advantages of the wireless sensor network. We are discussing entire concepts about TOSSIM in WSN. We hope this article is providing the best knowledge about WSN and its project areas. We have more number of developing and developed projects based on WSN.
