Resource-Aware Service Architecture for Mobile Services in Wireless Sensor Networks

After deployment of sensor nodes, the software of sensor nodes usually cannot be changed anymore. Thus, dynamical changing requests to the network and adaptations of the evaluation methods are not possible. This paper presents a service architecture Resource-Aware Service Architecture RASA for small, mobile, and resource-critical sensor networks. This architecture...
