In this work we study the performance of a heterogeneous wireless sensornetwork which consists of 4 different hardware platforms (TelosB, SunSPOT,Arduino, iSense). All hardware platforms use 802.15.4 compliant radios. Due topartial implementation of the standard, they do not communicate out of the box.A first contribution of our work is a careful description of the necessarysteps to make such a heterogeneous network interoperate. Our software code isavailable online. We deploy a heterogeneous network testbed and conduct athorough evaluation of the performance. We examine various network performancemetrics (e.g., transmission rate, receiving rate, packet loss, etc.), andassess the capabilities of each device and their intercommunication. We useddifferent setups (e.g., distance between transmitters and receivers, etc.) tobetter understand the network limitations for each hardware platform.
