Variabilities of Wireless and Actuators Sensor Network Middleware for Ambient Assisted Living

Wireless and Actuators Sensor Networks (WSANs) are one of the key technologies for supporting many Ambient Assisted Living applications. WSAN applications development poses new challenges like dealing with diverse low-level programming abstractions and the heterogeneity of nodes with critical resource limitations. Middleware platforms can hide from final developers the complexity of managing different types of hardware and software variability by applying a Software Product Line approach. This paper proposes a family of middleware for WSANs that can be customized according to the constraints imposed by the particular device, network and applications.
