The current state of the art in wireless sensor nodes, both in academia and the commercial world, is a fractured landscape of designs which mostly address individual problems. The most common commercial design derives directly from a mote developed at the University of California, Berkeley around 1999, and presents only moderate, incremental improvements over the original design. No designs yet present a comprehensive, intelligent design befitting a modern system.

By using dynamic power management, deep system configurability, autonomous peripheral modules, and multiple CPU architectures, this thesis presents a flexible and efficient node architecture. Modules in a system communicate between each other to coordinate their activities and power levels. Special attention is given to power sourcing and distribution. Individual peripheral boards supply their own drivers to the CPU using architecture-independent code. The platform may be configured to work with most networks, sensor types and power sources due to its improved connectivity and hierarchical design.

The resulting Configurable Sensor Node (CoSeN) architecture is competitive with existing designs on price, size and power while greatly exceeding most of them on performance, configurability and application potential. The CoSeN architecture is validated through a prototype implementation.

Alumna Jedda Puzon ’11, information system management, and current student Lauren Roepcke founded the company in 2011, and recently released a spring line.

Said marketing director Puzon: “We promote individuality and that can be seen with our tag line ‘Tag your own state of mind.’ We encourage self-expression through all art forms.”

One college is taking its war on frats to the web.

Don’t even think about joining a fraternity Facebook group if you are a freshmen at Princeton or you’ll face suspension.

The university does not officially recognize Greek organizations on campus because they believe they promote social exclusiveness and excessive alcohol consumption, but now they are taking an active stance against new students associating with Greek life.

Any freshmen who rushes, pledges, or even joins a social media group that has to do with a fraternity or sorority faces suspension, as well as any Greek member who solicits a freshmen. Princeton is following through on this policy with the thought that a freshmen in a Greek organization will limit their social options.

Despite Princeton’s unwillingness to accept Greek life on their campus, 15% of their students are involved, and do not feel that they have a negative impact on freshmen who want to get involved and meet upperclassmen.

Does Greek life limit social groups that students get involved with? Is Princeton’s new policy justified?
