Despite the various applications of Wireless Sensor Network (WSN), experiences from real WSN deployments show that protocol implementations in sensor nodes are susceptible to software failures, which may cause network failures or even breakdown. Pre-deployment protocol conformance testing is essential to ensure reliable communications for WSNs. Unfortunately, existing solutions with simulators cannot test the exact hardware and implementation environment as real sensors, whereas testbeds are expensive and limited to small-scale networks and topologies. In this paper, the authors present RealProct, a novel and reliable framework for testing protocol implementations against their specifications in WSNs.
