Location-aware, Trust-based Detection and Isolation of Compromised Nodes in Wireless Sensor Networks
14 years 5 months ago
The detection and isolation of compromised nodes in wireless sensor networks is a difficult task. However, failure to identify and isolate compromised nodes results in significan...
