Wormholes No More? Localized Wormhole Detection and Prevention in Wireless Networks
A number of protocols have been proposed to date to defend against wormhole attacks in wireless networks by adopting synchronized clocks, positioning devices, or directional antenn...

Scoop: An Adaptive Indexing Scheme for Stored Data in Sensor Networks
We present the design of Scoop, a system for indexing and querying stored data in sensor networks. Scoop works by collecting statistics about the rate of queries and distribution ...

Mesh-Based Coverage for Wireless Sensor Networks
—Wireless Sensor Networks (WSNs) consist of spatially-distributed autonomous sensors that can cooperatively monitor physical and environmental conditions. Because of sensors’ r...

Mobility Control for Complete Coverage in Wireless Sensor Networks
In this paper, we propose a new control method to cover the “holes” in wireless sensor networks. Many applications often face the problem of holes when some sensor nodes are d...

Coverage and hole-detection in sensor networks via homology
We consider coverage problems in sensor networks of stationary nodes with minimal geometric data. In particular, there are no coordinates and no localization of nodes. We introduc...
