Research project: SENSES

The primary goal of the SENSES ((Software Environment for Networks of Sensors and Embedded Systems) project is to build a scalable and an extensible software environment for sensor network applications. The project is building system software (including operating systems and virtual machines), software synthesis and scaling  tools, distributed middleware, and programming languages for sensor networks. The details of the project can be found on the main SENSES web site.

Previous projects
 

Ariel: Adaptive,  fault-tolerant and secure  programming environment for distributed systems

Goals: Develop  novel language and runtime system mechanisms for supporting safe and secure executions of distributed programs.   There are three components of the research:

• Development of languages and applications that use mobility as a basis for distributed programming;
• Development of efficient and scalable runtime system support for mobile programs; and
• Support for secure execution of mobile programs.
