ABSTRACT

The wireless sensor networks (WSN) are expected to become a radical innovation similar to the internet. The diversity in application areas results in differing requirements for the system in terms of reliability, availability, quality of sensor data, latency constraints, energy—efficiency, and longevity. The form of testing can only determine the presence of errors and not their absence, testing is the primary method employed in software, hardware, and system development. The validation and testing methodologies thus need to address the domain–specific intricacies and challenges. The sensor nodes are highly concurrent and only loosely coupled through unreliable, wireless communication. The testing of a comprehensive WSN system includes the checking of predicates on the distributed, global state. The test platforms used in WSN validation include well–known simulators with their origin in traditional network design like or GloMoSim. The validation and testing methodologies and tools need to provide support to arrive at a functionally correct, robust, and long-living system at deployment time.
