Enhanced Security Technique For WSN Nodes

Enhanced Security Technique For Wireless Sensor Network Nodes Wireless sensor network (WSN) have become a complete solution in making use of low power implementation and embedded systems. Many different security protocols have been proposed that allow some form of security…

Wireless Sensor Networks: Technology and Applications

Wireless sensor network encompasses the characteristics of authentication, privacy, integrity, non-repudiation, and anti-play back. The greater the dependency of information sent or received in the network, the greater the security risks. Various security issues have been considered in ad hoc…

Dennis Hong: My seven species of robot

Dennis Hong introduces seven award-winning, all-terrain robots — like the humanoid, soccer-playing DARwIn and the cliff-gripping CLIMBeR — all built by his team at RoMeLa, Virginia Tech. Watch to the end to hear the five creative secrets to his lab’s…

Remote Sensing and Satellite

Communication that involves the use of an active or passive satellite to extend the range of a communications, radio, television, or other transmitter by returning signals to earth from an orbiting satellite. For example, researchers like Prof Gorry Fairhurst of…

Applications of Energy Harvesting

The rapid growth in the field of wireless sensor networks has highlighted the issue of powering remote sensor nodes. The requirement to change batteries, or recharge other power sources, places an unwanted additional maintenance and cost burden on such wireless…

What is Wireless Sensor Network

Wireless Sensor Networks in Brief: Wireless Sensor Network (WSN) can be referred to as a collection of spatially spread and dedicated sensors that have the tendency to monitor and record the physical conditions of its surroundings; thus, organizing the collected…
