Group rekeying for filtering false data in sensor networks: a predistribution and local collaboration-based approach
— When a sensor network is deployed in hostile environments, the adversary may compromise some sensor nodes, and use the compromised nodes to inject false sensing reports or modi...

Mobile-assisted localization in wireless sensor networks
Abstract— The localization problem is to determine an assignment of coordinates to nodes in a wireless ad-hoc or sensor network that is consistent with measured pairwise node dis...

Maintaining Stable Node Populations in Long-Lifetime Sensornets
Sensornets provide coverage of physical phenomena over extended periods, perhaps months or years. However, active nodes may deplete finite batteries within days, and are prone to...
