Wireless Sensor Networks (WSN) comprise autonomous embedded nodes that combine sensing, actuation, and distributed computing with small size and low energy. Testing of WSNs is challenging due to distributed functionality, lack of test and debug interfaces, and limited communication, computation and memory resources. This paper presents the design and(More)
Wireless Sensor Networks (WSNs) comprise embedded sensor nodes that operate autonomously in a multi-hop topology. The challenges are unreliable wireless communications, harsh environment, and limited energy and computation resources. To ensure the desired level of service, it is essential to diagnose performance issues e.g. due to low quality links or(More)
