On a wired network, physical authentication is implicitly provided by access: if a user is able to plug a cable into a network socket, he must have cleared other security checks s...
Abstract—Wireless sensor networks(WSNs) have been regarded as an incarnation of Ad Hoc Networks for a specific application. Since a WSN consists of potentially hundreds of low c...
Key establishment plays a central role in authentication and encryption in wireless sensor networks, especially when they are mainly deployed in hostile environments. Because of t...
Nodes in sensor networks often encounter spatially-correlated contention, where multiple nodes in the same neighborhood all sense an event they need to transmit information about....
— In large Wireless Sensor Networks (WSNs), each hop might incur varying delays due to medium access contention, transmission and computation delays. Fast and efficient query re...
