Optimizing sensor networks in the energy-latency-density design space
TL;DR: This work proposes a new technique, called sparse topology and energy management (STEM), which efficiently wakes up nodes from a deep sleep state without the need for an ultra low-power radio, and shows that this scheme results in energy savings of over two orders of magnitude compared to sensor networks without topology management.
Proceedings ArticleDOI
Topology management for sensor networks: exploiting latency and density
TL;DR: A hybrid scheme, which takes advantage of both setup latency and network density to increase the nodes' lifetime, and integrates efficiently with existing approaches that leverage the fact that nearby nodes can be equivalent for traffic forwarding.
Proceedings ArticleDOI
STEM: Topology management for energy efficient sensor networks
TL;DR: This work proposes a new technique, called sparse topology and energy management (STEM), that dramatically improves the network lifetime by exploiting the fact that most of the time, the network is only sensing its environment waiting for an event to happen.
Proceedings ArticleDOI
On communication security in wireless ad-hoc sensor networks
TL;DR: The approach is to classify the types of data existing in sensor networks, and identify possible communication security threats according to that classification, and propose a communication security scheme where for each type of data the authors define a corresponding security mechanism.
