Diversify sensor nodes to improve resilience against node compromise
A great challenge in securing sensor networks is that sensor nodes can be physically compromised. Once a node is compromised, attackers can retrieve secret information (e.g. keys)...

Characterizing energy consumption in a visual sensor network testbed
Abstract— In this work we characterize the energy consumption of a visual sensor network testbed. Each node in the testbed consists of a ”single-board computer”, namely Cross...

Performance characteristics of collaborative beamforming for wireless sensor networks with Gaussian distributed sensor nodes
Collaborative beamforming has been recently introduced in the context of wireless sensor networks (WSNs) to increase the transmission range of individual sensor nodes. In this pap...

Application-Driven Node Management in Multihop Wireless Sensor Networks
A strategy for energy saving in wireless sensor networks is to manage the duty cycle of sensors, by dynamically selecting a different set of nodes to be active in every moment. We ...

Parameterless Broadcasting in Static to Highly Mobile Wireless Ad Hoc, Sensor and Actuator Networks
—In a broadcasting task, source node wants to send the same message to all the other nodes in the network. Existing solutions range from connected dominating set (CDS) based for ...
