wide applications of wireless sensor networks, there has been given tremendous attentions by researchers in recent years. In result there is development of low-cost, low-power, multifunctional sensor nodes that are small in size and communicate untethered in short distances. These tiny sensor nodes, which consist of sensing, data processing, and communicating components, leverage the idea of sensor networks based on collaborative effort of a large number of nodes. Sensor nodes in such a network are

the decision-making process. A new trust model and a reputation system for WSNs can be proposed. The trust model establishes the continuous version of the reputation system applied to binary events and presents a new trust and reputation system for sensor Networks. This approach for mixing of second hand information from neighboring nodes with directly observed information to calculate trust between nodes in WSNs. Trust metrics can be used to evaluate the trust value of each node in the clusters.

Sensor hubs may be homogeneous or heterogeneous. These systems are

Abstract- Wireless sensor networks have many advantages over traditional wired sensing technology, due to their embedded construction. This technology has been used in agricultural scenario because of the need for enhancing precision, quality and quantity in farming. This paper is about developing a prototype for the system which utilized a real time wireless sensor network to communicate wirelessly with a pest management system that measures the various parameters like air temperature, air humidity

warming. Wireless sensor networks are used for detecting the natural events by measuring the temperature, air pressure, vibration, etc. and generate alarms. WSNs can measure the agitation of buildings, CO2 levels, and weather monitoring, etc. (Yawut & Kilaso, 2011). WSN that utilized Zigbee/IEEE802.15.4 is utilized as a weather monitoring network. It sends the information about the weather and generates hazard alarms. Decision tree techniques are used for analysing the data at sensor site. Weather data

Wireless Sensor Networks. 2.1 Literature Review Heinzelman et al. (2000) [1] Based on their findings that the conventional protocols of direct transmission, minimum-transmission-energy, multihop routing, and static clustering may not be optimal for sensor networks, proposed LEACH (Low-Energy Adaptive Clustering Hierarchy), a clustering-based protocol that utilizes randomized rotation of local cluster base stations(cluster-heads) to evenly distribute the energy load among the sensors in the network

Paper 228.797 Project Report on “Energy Harvesting and Efficient Hardware Design considerations for Wireless Sensor nodes” Prepared by: Mukesh Mishra Date: 21/03/2016 1. Introduction A Wireless Sensor Network (WSN) is comprised of multiple tiny devices called nodes or motes. These are distributed spatially in an environment to monitor sense and compute data wirelessly. The role of a sensor node is to evaluate different tasks. First, a node has to sense physical conditions and exchange the information

mass airflow sensor operates on the theory of heat transfer due to mass gas flow across the surface of the sensing element. The rotameter indicates flow in standard cubic feet per minute (SCFM). Simulink program was built to acquire voltage values from the pressure sensor, then after plotting the voltages Simulink program was changed to calculate the actual pressure and flow values being measured by the sensors from the voltages that the sensors output by adding “Fcn” block. These values

1. What ethical issues are involved in the use of tracking sensors? Tracking sensors are intended to help companies evaluate their employees and productivity. The ethical issues involved in using tracking sensors begins with the threat to privacy. There is potential abuse that could be taken from employers having too much information and micromanaging their employees. Many employees feel threatened by the thought of being monitored while in the workplace, and being evaluated by tone of voice, communication

thousands of Canadians with celiac disease or gluten sensitivity, going out to eat is sometimes difficult and with anxiety because any item on the menu could have the possibility of giving you bad symptoms if it contains gluten. However, the Nima Sensor, which was created in late 2015, would work to put their minds more at ease by helping detect 20ppm or more of gluten in a drink or food in exactly two minutes (Park, 2015). All it takes is inserting a sample into the well of the device, and an antibody
