INTERNET OF THINGS ON WIRELESS NETWORK
In context with internet of things, there is use of wireless sensor that are connected with quite these wireless network devices and every node has a sensor to be able to detect heat, light and maybe pressure. These wireless sensor networks are regarded as sophisticated revolutionary devices that are useful in transmitting significant information in the dynamic industry system. It is so much efficient and reliable to the information system infrastructure because it is much flexible and easy to develop when compared to wired networks. History and overview Generally, internet of things was developed with the idea of wireless sensor networks. The main invention on these devices began in the early 1980s by the scientists but then it came into much interest to the scientists 2001 where they developed interest on it.
This is major progress in the market and the fastest growing digital technology. Features of internet of things on wireless network These wireless sensor networking are known to be several nodes of network sense, incorporate and control the environment between persons and remote computers. These nodes fetch data transmission through hopping and then get to gate way nodes through multiple hop rooting and then reaches the final destination of data management through an internet. For a complete cycle of data transmission, there have to be the sensor nodes, gate ways and a network or satellite connection for the process to reach the observer from the sensor field. i) Sensor nodes This is the most significant part of a wireless sensor networking.
Such a system requires less power supply voltage and is usually very small in size. Nevertheless, their field applications is limited by their battery reliability. Again, harvesting of ambient energy is observed through miniaturization of electric crystals, micro oscillators, thermoelectric elements, electromagnetic wave receivers and by the convention optical cell power supply module. Most industries use such devices for energy acquisition to commercialize applications for sensor networking. For instance, a German based company provide light energy for devices harvesting, temperature-based harvesting energy and vibration devices for harvesting energy used in designing devices for monitoring air and customized lighting. That is, wireless metropolitan area network, wireless local area network, wireless personal area network, and wireless wide area network. Although, the transmission level is unsuitable for application that require wireless devices iv) Topology Wireless sensor networking has a gateway and multiple network nodes used in internet connection.
The process of deploying this wireless sensor networking involves. Firstly, the receiving of status from other nodes by the sensor network nodes to simultaneously read the status of each other. Next, the organization of the sensor network nodes into a mesh like typograph of connected network. This is avoided by aggregation of data technique. The process of Integration of various information copies into one copy, to effectively meet the needs of the user in middle sensor nodes is called data aggregation. vi) Security This is a major concern and a very significant feature on internet of things with wireless network and in some cases, we have watched on Hollywood films on how the future might be. The vision on internet of things is so close to the Hollywood films’ vision.
Both are having kind of common visions in that: the machines working on wireless network becomes very much significant in the current automated society. Data encryption as an algorithm changes the real data information on sensor node(s), hence making it difficult to unauthorized user, even if they access the encrypted data or not of the real information data. The application of public infrastructure is exposed to public activities and inevitable. Challenges facing internet of things on wireless network i) High concurrent access Technology for wireless networking embedded in industrial applications and smart grids, perform more rigorously simultaneously as expected. For instance for a smart grid, its application control in transformers always need an average latency of 0. 667 for networks having several sensor nodes, networks latency(second level) with five hundred nodes within the a given coverage area and network latency (minute level) for future developed area coverage applications with per say a thousand of nodes.
Therefore, creating an urgency for building more flexible and open system framework for bottleneck breaking of internet of things. To ensure sharing of control demand or convenience sensor information while at the same time integrating data isolation into sensor network, calls for pervasive computing in order to develop sensor networks. This leads to the utilization of web technology as a natural technology choice so as to ensure sharing of heterogeneous resources and attain pervasive computing and as it forms the basic framework for services and resources sharing within different platforms. iii) It has ultra-large sensing device access Installing wireless devices in the distant future is predicted to grow exponentially due to the demanding requirements for monitoring concurrent comprehensively in industries, electricity, and transportation.
For instance, in monitoring of production equipment in industries, it is thus crucial all devices to install different sensors for measuring such states of the device such as in ABI Research, vibration and temperature, billions of new machines and in the future there will be quite a significant quantity of these devices accounting for a large proportion of the scale. ii) Developing common models to ensure security Deployment of more nodes impact the general performance of these nodes as well as security services addition in the WSNs such as in infrastructure. Research firms should work together in developing shared models that ensure each layer security and ones that work collaboratively with one another. iii) High concurrent access technology Implementation of operational and developing high-concurrent access technology on top of current access technologies, despite of their historical context novelty.
