In this paper a multi-sensor data fusion approach for wireless sensor network based on bayesian methods and ant colony optimization techniques has been proposed. In this method, each node is equipped with multiple sensors (i.e., temperature and humidity). Use of more than one sensor provides additional information about the environmental conditions. The data fusion approach based on the competitive-type...
In today's world Wireless Sensor Networks (WSNs) has gained a lot of recognition because of its wide-ranging areas of applications. Sensor nodes in WSNare connected to each other by networks, mainly powered by a battery source. These sensor nodes have lesser amount of power and computational capabilities. Typically, sensor nodes are deployed in remote areas where replacement of their batteries once...
This Paper Presents a Portable vital signs monitoring system using GSM. Design and implementation of vital sign monitoring system to monitor vital sign is based on internet and wireless sensor network. The system consists of three tiers that is Sensing, Communication and presentation. Sensor layer consists of no of the sensor unit suitable for vital signs monitoring. The Communication layer helps...
Internet of Things in which object, animal, people is identified uniquely according to their identifier in the network and data transfer over Network without having directly human to human or human to machine interaction. IoT is used in education to improve E-Learning. It is available in different formats. Propose a system combining the different applications of e-learning with the help of Internet...
Internet of Things (IoT) is extension of current internet to provide communication, connection, and inter-networking between various devices or physical objects also known as “Things.” In this paper we have reported an effective use of IoT for Environmental Condition Monitoring and Controlling in Homes. We also provide fault detection and correction in any devices connected to this system automatically...
Design of effective WSN topology is major issue in prolonging network lifetime in wireless sensor networks. Designed topology is expected to be efficient and balanced in terms of energy consumption. This paper proposes Genetic Algorithm (GA) based energy efficient disjoint path routing scheme which will help in prolonging lifetime of wireless sensor networks. Simulation results shows that proposed...
Energy consumption in wireless sensor network is of paramount importance, which is demonstrated by large number of algorithms, techniques and protocols that have been developed to save energy and to extend lifetime. In WSN for mission critical application two performance metrics are: reliability and energy efficiency. In literature CDS based technique is used to achieve reliability. CDs allow communication...
WSNs consists several nodes spread over experimental fields for specific application temporarily. The spatially distributed sensor nodes sense and gather the information for intended parameters like temperature, sound, vibrations, etc for the particular application. In this paper, we evaluate the impact of different algorithms i.e. clustering for densely populated field application, energy backup...
The wireless sensor networks are designed to install the smart network applications or network for emergency solutions, where human interaction is not possible. The nodes in wireless sensor networks have to self organize as per the users requirements through monitoring environments. As the sensor nodes are deployed in an inaccessible location for particular mission, it is difficult to exchange or...
