WSN for Smart Infrastructures: Business Prospects

Europe is on track for a large scale investment that will create a sustainable transport network with a project called “Connecting Europe Facility, aimed at increasing the benefits of pan-European freight and passenger traffic infrastructure projects. The Fund will have…

Sniffer WSN Gets Boost From Microchip Creation

Pair of engineers at California Institute of Technology (Caltech) has created a Tiny; inexpensive silicon microchips that generate and radiate high-frequency electromagnetic waves. This imager can penetrate a host of materials without the ionizing damaging effect of x-rays. The chips…

Will The Future Be Perfect?

The emergence and the implementation of Internet of Things (IoT) which brings the Internet, mobile and cloud computing into great light will bring lots of new micro-consumers into the fold and will reinvigorate the passion of innovation in industries. It…

Step-by-Step: Writing Contiki Programs

Hands –on simple instructions on how to program WSN motes on the Contiki operating system platform is illustrated here. This is one of the experiences I had while attending the CONET summer school of 2011 with the developers of Contiki.…

Collision Avoidance Systems Emerges

A cheap, small and portable sensor has been made by some US scientists to help the automobile Industry avoid collision. The scientists have used metamaterials to construct the imaging system, which samples infra-red and microwave light. This system which has…

AES Implementation on MicaZ with Contiki OS

Advanced Encryption Standard has been used to double the security of the MicaZ wireless sensor network nodes by the Wireless Sensor Network research group at the University of Aberdeen. We can recall that it was in the year 2001 that…

Wireless Sensor Networks with Contiki

The designers of operating systems for sensor nodes are often faced with the challenge of finding the right abstractions and lightweight mechanisms that offer a rich enough execution environment, while remaining within the system’s strict resource limitations. My hunt for…
