Title
Terra: Flexibility and Safety in Wireless Sensor Networks
Abstract
Terra is a system for programming wireless sensor network (WSN) applications. It combines the use of configurable virtual machines with a reactive scripting language that can be statically analyzed to avoid unbounded execution and memory conflicts. This approach allows the flexibility of remotely uploading code on motes to be combined with a set of guarantees for the programmer. The choice of the specific set of components in a virtual machine configuration defines the abstraction level seen by the application script. We describe a specific component library built for Terra, which we designed taking into account the functionality commonly needed in WSN applications—typically for sense and control. We also discuss the programming environment resulting from the combination of a statically analyzable scripting language with this library of components. Finally, we evaluate Terra by measuring its overhead in a basic application and discussing its use and cost in a typical monitoring WSN scenario.
