Visualisation of wormholes in underwater sensor networks: a distributed approach
: We propose a distributed mechanism, Dis-VoW, to detect wormhole attacks in under-water sensor networks. In Dis-VoW, every sensor reconstructs local network layout using multi-dim...

Exploiting local node cache in top-k queries within wireless sensor networks
Top-k queries are a popular type of query in Wireless Sensor Networks. Typical solutions rely on coordinated root-tonodes and nodes-to-root messages and on maintaining filters at...

A Feasibility Check for Geographical Cluster Based Routing under Inaccurate Node Localization in Wireless Sensor Networks
Localized geographic single path routing along a wireless network graph requires exact location information about the network nodes to assure message delivery guarantees. Node loc...
