Research Focus
Minimizing power consumption of sensors for localization applications

Description of Research
In applications such as inventory management, tracking the location of an object is very important. Tracking or localization of a mobile node has been studied extensively, however, very little research has been conducted to address issues in energy consumption. The tracked object has a sensor attached to it and is free to move around in a sensor network. However, the cost of this mobility is the use of batteries for powering the sensor. In order to use such a system efficiently, the life of the battery must be extended as long as possible. The use of optimized algorithms and energy efficient hardware is being researched to solve this problem.

Example of how my research is integrated into my GK-12 experience
I have developed a module for a computer science class where the students learn and experiment with Digital Logic circuitry. Students learn the fundamentals of Boolean Logic and how logical expressions can be implemented using electronic logic components. Once students have gained some familiarity, they work in groups of three to four to build a Adder Circuit capable of adding two 2-bit binary numbers. Once they get their individual circuits working, then all the circuits of all the groups are put together to form a circuit that is capable of adding much larger binary numbers such as 10 or 12 bits wide. This experience was exciting for the students because they are exposed to the fundamental theories that form the foundation of computers. They also begin to see how computers perform calculations.
