In this work we develop a secure communication protocol in the context of a Remote Meter Reading (RMR) System. We first analyze existing standards in secure communication (e.g. IP...
We introduce a dynamic battery model that describes the variations of the capacity of a battery under time varying discharge current. This model supports a co-design approach for ...
Recent research in sensor networks has raised issues of security for small embedded devices. Security concerns are motivated by the deployment of a large number of sensory devices...
Once the battery becomes fully discharged, a battery-powered portable electronic system goes off-line. Therefore, it is important to take the battery behavior into account. A syst...
We present an adaptive, feedback-based, energy estimation model for battery-powered embedded devices such as sensor network gateways and hand-held computers. Our technique maps ha...
