A Publish/Subscribe-based Programming Language for Sensor Networks

Sensor networks constitute an efficient solution for gathering data on such events and feeding the evacuation simulation. Sensor networks software(SNS) is considered as a new software paradigm in the sensor networks environment, with the characteristics of cooperation and flexibility. SNS brings challenges to programming technologies in terms of model, language and platform. This paper presented a new programming language, called PSPL, for modeling and implementing the architecture of sensor networks applications using publish/subscribe paradigm. Considering bridging the gap between sensor nodes and enterprise applications where sensor data is used, PSPL was defined by integrates organization abstract and event-condition-action(ECA) technology. PSPL was composed of group, role, and behavior agent. Rule management and matching is designed through two aspects, such as subscription management and rule matching. A run-time environment, namely PSPL_RTE, was developed for development, compile, deployment and running of PSPL programs. Simulation experiments imply that PSPL is simplicity, while ensuring good flexibility and co-operability.
