This paper reflects on experiences in deploying middleware for a body sensor network, using commercial biosensors. Three types of issues are highlighted that arose during the deployment, which impact middleware design in particular: 1) How can the architecture cope with different levels of data fidelity and propagate those levels to the applications? 2) What is the optimal way to handle temporary disconnections from sensors? and 3) How should the middleware implement sensor-specific peculiarities? Although these issues are described using a specific and demanding health care scenario, we argue that the underlying causes tend to be archetypal for a generic set of sensor network middleware. Awareness of these problem categories and possible solutions are therefore generally relevant for other researchers working on middleware designs for all kinds of sensor networks.
