Bis/531 Research Assignment

In a society where technology grows exponentially, the amount of information available is practically endless. Whether one needs to know ingredients to a recipe, or cures to an illness, the Internet has an answer. The simplicity of the Internet, however comes with a major drawback: the quality of the data. In Peter Cardon’s book Business Communication: Developing Leaders for a Networked World, he explains that there are five main components that one should consider in evaluating quality data: reliability, relevance, adaptability, expertise, and biases.

Data is very important thing in every business, especially in today’s dynamic world where optimal use of data leads to success in shorter span of time as lots of companies are struggling for truthful and accurate data. These data must be analyzed in exact time and in a proper way so that the decision is more effective, but the data we receive are very redundant and carry lot of space in our system. This creates a challenge for the Analytics people to remove the redundancy and bring out only those relevant data that aids in decision making process. Master Data Management is a solution for such Analyst who wants to eliminate the redundant and inconsistent data of the organization (Vinculum, 2016).

What was the impact of data quality problems on the companies described in this case study? What management, organization, and technology factors caused these problems?

This report ia mainly cinsist of the research on Reliability and validity of the range of the tests for quality assurance of Hardware, Networks and Software. We will going to discuss about all the testing of software and hardware network models in this report which helps in finding the realiability and validity of the same. Discuss about the quality assurance and quality control concept and all the models use in this process is also discussed in it. This report is based on various recent articles. Now we are going to discuss it in our next topics.

Wireless Sensor Networks (WSNs) are revolutionizing the way people interact with the physical world. The use of WSNs is rapidly growing in various types of applications. Some of these applications have strong timeliness constraints [2]. Timeliness is a crucial factor in safety-critical applications. In general terms, timeliness refers to the

Abstract— the data aggregation is mostly used energy efficient mechanism in Wireless Sensor Networks (WSN). Preserving data security is a challenging problem in wireless sensor networks. Because of the resource characteristic, security & privacy issues there in assume critical investigation. Many aspects of investigation, one has been the design of a secure clustering protocol in which a sensed data or information to be delivered to an appropriate receiver securely and efficiently with least amount of energy consumption. Different methods are used to solve problem of security. We shows that different technique and method in this paper.

Advancements in the information technology sector have brought many benefits to the people all around the world.  Today with computer networking, we can chat, speak and see each other over a long distance. Data communication refers to the transmission of the digital signals over a communication channel between the transmitter and receiver computers. Communication is possible only with wired and wireless connectivity of the computers with each other.

Sensor network protocols have a unique capability self-organizing. Another interesting feature of wireless sensor networks is that the sensor nodes cooperate with each other. Sensor nodes have an in-built processor, using which before transmission raw data is processed. These features facilitate wide range of applications of wireless sensor networks like biomedical, environmental, military, event detection and vehicular telematics.

[8] Discussed a substantial escalation in data quality based on the observation of statistical analysis before and after using automated ETL.

There are many principles for the data quality that ensure the data quality for the data entered to a database. The most significant principles for the data quality include:

Abstract: We analyze the wireless sensor networks protocols and present a classification and comparison of routing protocols. Several routing protocols have been projected to maximize the sensor networks life span. Nevertheless, most of these solutions attempt to determine an energy efficient path and don’t account for energy consumption balancing in sensor network. This frequently leads to network partitioning. The aim of this paper is to evaluate, analyze and compare three routing protocols (LEACH, CBR and MBC) that balance energy consumption, through a mathematical model and simulations. This paper will present a performance comparison of protocols LEACH, CBR and MBC based on parameters such as packet loss, average energy consumption, average control overhead, and better adaptivity to a mobile environment by using the NS-2 simulator.

Due to the limitations of mobile environments (such as energy autonomy constraints, limited storage capacity, variable bandwidth, hardware heterogeneities, etc), this quality system is not well-suitable to be entirely applied to these types of environments. Therefore, further analysis is needed in order to identify which aspects from this standard are applicable to mobile environments. Such analysis was done by Idri et al cite{idri2013use} in which they created a framework for identifying the quality characteristics shown in ISO 9126 that may be impacted by the limitations in the mobile

Wireless sensor networks frequently consists of a huge number of less expensive radar networks that rigorously partial detecting,computation and communique abilities.due to source regulated radar nodules,this one is essential to diminish the extent of data broadcast so that the normal radar life span and the global bandwidth operation exist upgraded.data transmission in the network.As wireless sensor systems are frequently arranged in distinct and unfriendly locations to transfer complex data,radar nodules are disposed to node conciliation doses and safety problems like data combination protocol,need to be considered with safety in notice.this sheet examines the connection among safety and data combination procedure in wireless node systems.a classification of protected data combination protocol 's is agreed by plotting the present "state-of-the-art" effort in this part.In count,centered on the current investigation ,the uncluttered investigation zones and upcoming investigation commands in protected data combination perception stay provided.

Abstract-Key management is one of the most important issues of any secure communication with the increasing demand for the security in wireless sensor networks (WSNs) it is important to introduce the secure and reliable key management in the WSNs.Data confidentiality and authenticity are critical in WSNs. Key management objective is to secure and keep up secure connections between sensor nodes at network formation and running stages.

By dividing the WSN into fixed WSN and mobile WSN, it proposes a measure to identify and deal with the sensor node faults. Additionally, it suggested a mechanism for the prediction of the energy consumption of sensor networks.
