Wireless Sensor Network

Question: Discuss about theWireless Sensor Network. Answer: Wireless Sensor Network for Water Quality Monitoring In this report we will discuss about use of wireless sensor network in case of domain of water quality monitoring. The purpose of this report is to draw a network diagram of wireless sensor network for water quality monitoring. In this network diagram, we will represent topology and types of nodes such as normal node, sink node and clusterhead node. Besides this, we will also emphasize on some other important information regarding wireless sensor network in this particular domain. Wireless Sensor networks provide significant advantages both in case of cost and distributed intelligence. Besides this, reduction in expenses of installation and maintenance is also possible with the help of wireless sensor networks. These networks have considerable attention in environmental and industrial monitoring and control applications. Due to these reasons, we have decided to use wireless sensor network for monitoring quality of water. As we know that due to polluted environment, quality of water is diminishing day by day and it effects health of human beings. That is why now water controllers are emphasizing to control quality of water and using advanced wireless network sensors. Now in next segment of this report we will draw a diagram and discuss about network design of wireless sensor for water quality monitoring. Network Design for Wireless Sensor System for Water Quality Monitoring Here in this segment of report we will discuss in detail network design of wireless sensor that will be used for measuring water quality monitoring. In this diagram, sensor nodes and various modules are used to control monitoring. This whole process of monitoring is done with the help of internet. The main components of this whole wireless sensor system are database, data visualization, email alerts etc. All these components are connected through internet with each other. (Monitoring, 2014) As we can see in above image that how quality detection has been carried out with the help of wireless detection system. Traditionally water quality detection was carried out manually and in this process water samples are collected manually and these are sent to the laboratories for evaluation. But this method was failed to deliver real time data. That is why river water quality monitoring system has started. The above given system architecture is strong and secure for implementing this process of wireless sensor system to check water quality. Now in next segment of this report, we will emphasize on some essential components of this given architecture of wireless sensor system. A better design of a system depends upon some essential choices such as goal of design, number of nodes required, environment for deployment and technology of choices. So in next segment we will emphasize on some essential choices that have used in development of this wireless sensor system. Goals of Designing Wireless Network for Water Quality Monitoring The main goal for above designed wireless network is monitoring of quality of water. As we have discussed above that conventional testing system for measuring quality was not so good. The main goal of this system is to provide real time data regarding quality of water and to monitor three essential parameters that are continuously affecting quality of water and these parameters are pH, temperature of water and conductivity. This is an effective benefit that is provided by wireless network.( Faustine, Mvuma, Kucel, 2014) Suitable Topology and Routing Protocols This is wireless network is based on hierarchal approach of network topologies. The reason for using this topology is that in this topology whole monitoring process is divided into four general areas such as forming a cluster for comprising of several wireless sensor nodes that are required for sensing, collection and processing of data and communication. On other side, if we talk about routing protocols then suitable routing protocol is hierarchal routing protocols that classify sensor nodes according to their functionalities. This is main reason for using this routing protocol. Is this Communication Event-Driven and Time or Query Driven To decide that this wireless system is communication driven, event driven and Time and Query driven, it is required to check application, scalability of network and message. This wireless network sensor is event driven and in this a message will be sent whenever a node will be detected. This same system is implemented in this wireless system. (Google Books., 2016) Suitable Wireless System Best Suited for Application For this above discussed application, suitable wireless system is random system which is dynamic in nature because dynamic system provides help to manage network system according to changes in requirement. In case of dynamic system it is easy to add and modify components according to requirements. (Ieeexplore.ieee.org, 2016) Security Needs for System Both wired and wireless systems required security from network attacks such as hacking, phishing and denial of service attack and others. That is why security is very necessary to maintain confidentiality, integrity and availability. Confidentiality is related to security and privacy of data that is stored into system. In this wireless sensor networks confidential information must also be stored properly and only authorized access should be possible. In case of integrity, it is necessary to verify that updated and accurate data is accessed by all users. It means master record is updated only by administrator and it showing changes in all other connected databases. Availability means data should be accessible to all users who are connecting with database. But all users should be authorized and they should have login credentials to access their records from database. These are some essential choices to design this wireless sensor network for water quality measurement. If all these components will be used properly then successful results can get by users.
