Application Fields

Wireless network led to the development of Wireless Sensor Networks (WSNs). A Wireless sensor network is a set of connected devices, sensors, and electronic components that can transmit the information collected from an observed field to the relevant node through wireless links. WSN has advanced many application fields. It can change any kind of technology that can modify the future lifestyle. WSNs are composed of tiny wireless computers that can sense the situation of atmosphere, process the sensor data, make a decision, and spread data to the environmental stimuli. Sensor-based technology has created several opportunities in the healthcare system, revolutionizing it in many aspects. This chapter explains in detail wireless sensor networks, their protocol, and performance metrics. The impact and role of the Biosensor in a wireless sensor network and healthcare systems are depicted. The integration of the computer engineering program into the WSNs is addressed.

Data Redundancy

Middleware acts in between the application level and the lower level constructs which solve many wireless sensor network challenges. Still, middleware poses a number of issues such as energy constraint of devices, scalability, mobility, heterogeneity, data aggregation, data redundancy, dynamic networking requirements, security and Quality of Service. If data redundancy is reduced, then data aggregation and energy-related issues in middleware can be solved. An efficient middleware must have the ability to aggregate data from devices in such a way that data redundancy is reduced and hence, the amount of data transmitted to the sink is decreased. Classification algorithms can be used in middleware to reduce the duplication of data. Here, we use k-nearest neighbour algorithm for classification in order to prevent data redundancy in wireless sensor networks.

The purpose of this paper is calculating the availability of wireless sensor network for a virtual grid by using Markov model. Since, wireless sensor networks are constraints by energy, their energy consumption should be limited within a way to guarantee their quality of service. In this paper, availability and quality of service in a wireless sensor network with particular coverage are investigated by using an energy optimized algorithm and Markov process.

Wireless Sensor

In the deployment of a wireless sensor network, a portable device can be used on protocol analysis or in-situ network diagnose, which is more convenient than the traditional gateway solution. In this paper, based on the Android devolvement board and TelosB mote, the Android terminal was built to collect data from a wireless sensor network composed of TelosB motes. The middleware was implemented on this Android terminal to parse the sensor data and store the data into databases. The evaluation process verified the deign feasibility.
