wireless sensor networks which is an innovative and are within the broad spectrum of whites networks that are specifically designed to measure a small amounts of data and that data is related to sensor data. The little pieces of information like temperature sensors or open/close sensor are extremely valuable information as it provides insights into defense that might happen in their business processes. There are many wireless network, but the question arises is where do these wireless sensor network

home, a smart city and so on. Sensors are small, low battery operated devices which enable this smartness. Data produced from sensors pose a challenge to the traditional approaches of managing the data and cause towards the emerging paradigm of Big Data. As a circumstance, there is a requirement for three types of developments. First, technology should be available through smart devices anywhere and anytime. Secondly, a solution to overcome the limitations of sensor network framework. Thirdly, intellectual
ABSTRACT Wireless Sensor Networks are formed by autonomous nodes containing partial memory, better range of communication, power and capable bandwidth. WSN are used to inspect the corporal and environmental conditions through a system and perform data processing. However, during data acquisition different types of issues and circumstances are to be resolved. In this study, we have discussed about the data acquisition from wireless sensor networks having some faulty nodes. Here, we perform removal
Biometric technology provides several advantages over conventional security methods like pin, password, key, card etc. The Biometric system grants authentication by different physiological and behavioral traits of a person. Biometric systems are basically of two types based on the use of a biometric trait for identification and verification. The types of biometric system are • Unimodal biometric system • Multimodal biometric system The Unimodal system has an only single source of information for authorization
of many sensor nodes that can measure and report the user’s health state continuously. These sensor nodes are employed on the human body. The exact connected and location of the sensor nodes on the human body depend on the sensor type, size, and weight. Sensors can be worn as stand-alone devices or can be assembled into costume jewelry, applied as tiny patches on the skin, hidden in the user’s clothes, shoes or glasses, or even implanted in the patient’s body [23]. The exact number and type of the
A WSN is a type of wireless networks that consists of collection sensor nodes which are tiny devices. Each sensor node of the network has different processing capability. It may contain multiple types of memory (program, data and flash memories), have a RF transceiver, have a power source (e.g., batteries and solar cells), and accommodate various sensors and actuators. The nodes communicate wirelessly and often self-organize after being deployed in an ad hoc fashion [13, 14]. Optimum need of each

There exist some practices of using the super saturated solutions made by different chemicals to maintain the desired conditions for effective seed germination and growth. wireless remote monitoring system that can be utilized to precisely monitor and measure the prerequisite conditions of seedling germination. The rapid development and wide adaptability of wireless sensor networks in agriculture has increased the quality of the crops produced. Many researchers have worked

FPGA is used in the wireless sensor node design in order to enhance the processing capabilities of the system to meet the target applications. The sensor nodes in a wireless sensor network are normally microcontroller based which are having inadequate computational capacity related to various applications. This paper describes the selection, specification and comprehension of a wireless sensor node using the field programmable
changes, some gases produce like Carbon dioxide (CO2), Ammonia (NH3), Methane (CH4), Hydrogen sulphide (H2S). As the time passes, the decomposition goes ahead and the concentration of these gases increases in the storage environment. By using different gas sensors, detection of concentration of these gases in air can be done. By monitoring the concentration of these gases, we can estimate the quality of food kept in store. This detector detects the amount of some specific gases present in the air of
