Charging Your Batteries From Thin Air Using Energy Harvester
The rapid growth in the field of wireless sensor systems 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…
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…
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.…
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…
Internet – of –Things: Next Advancement of the Internet
Will China become the Game changer? Cisco Systems futurist Dave Evans predicts that the Internet of Things (IoT) will link approximately 50 billion machines and devices by 2020. His vision is a world of networked smart devices equipped with sensors…
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…
