Dynamic reconfiguration in sensor middleware

ABSTRACT

Middleware solutions for sensor networks have so far mainly focused on communication abstractions, ad-hoc message routing protocols, and power conservation techniques. We argue that customisation and dynamic reconfiguration of sensor network middleware are additional important dimensions to consider. This paper describes a sensor middleware that can be customised to suit different sensor application types, and provides a reflective approach for co-ordinated network-wide dynamic reconfiguration of sensor behaviour. To evaluate our approach we illustrate customisation and dynamic reconfiguration of the Gridkit sensor middleware in a flood-monitoring scenario.
