Sensei-UU - A Relocatable WSN Testbed Supporting Repeatable Node Mobility

General purpose testbeds for Wireless Sensor Network (WSN) systems are often deployed in lab environments. This means that the testbed environment may differ considerably from the target environment of a system with respect to e.g. radio interference and sensory input. Furthermore, many WSN scenarios include mobile nodes, such as mobile sensors and mobile sinks, whose movements can affect the experimental results considerably. Both these features pose a challenge to achieving consistent and reliable experimental results during the evaluation and testing of a WSN system.
