Poster Abstract: SEAL: An Easy-to-use Sensor Node Application Development System

Majority of potential wireless sensor network (WSN) users have no formal education in computer science. To make WSN application development more feasible and attractive to this target audience, we have designed and implemented SEAL, a domain-specific language for WSN application description. Our idea is based on the observation that even though the lowlevel details of WSN are swarming with complexities, a broad class of WSN applications are conceptually simple – they can be described either as sense-and-send or event detection. SEAL decouples the low-level networking and hardware details present in sensor networks from application logic, thus reducing the complexity visible to the user. We suggest that our approach leads to reduced source code sizes and faster development times, without sacrificing user freedom and energy-efficiency.
