Data-centric programming environment for cooperative applications in WSN

Due to recent evolution of MEMS technology, wireless sensor nodes will be computing nodes having more storage space and processing power, and wireless sensor networks (WSNs) will be more capable of processing complex, cooperative tasks just in time, without relying on cloud servers which may cause delay and consume WSN bandwidth. However, low level implementation of cooperative applications onto individual sensor nodes needs a lot of human efforts, and has a considerable gap with high-level requirement given by application developers. To fill the gap, we propose a support environment for WSN applications development. We design a language to describe high-level specification of cooperative applications on WSN and provide an algorithm that translates the given high-level specification into program codes of sensor nodes. We have shown some example descriptions of highlevel specifications and have evaluated the quality of generated programs through several experiments.
