How to distribute sensors in a random field?
In this paper, we study the optimal way of distributing sensors in a random field to minimize the estimation distortion. We show that this problem is equivalent to certain proble...

A Spatiotemporal Approach for Secure Range Queries in Tiered Sensor Networks
Abstract—We target a two-tier sensor network with resourcerich master nodes at the upper tier and resource-poor sensor nodes at the lower tier. Master nodes collect data from sen...

Secure Range Queries in Tiered Sensor Networks
—We envision a two-tier sensor network which consists of resource-rich master nodes at the upper tier and resourcepoor sensor nodes at the lower tier. Master nodes collect data f...

Attack-Tolerant Time-Synchronization in Wireless Sensor Networks
—Achieving secure time-synchronization in wireless sensor networks (WSNs) is a challenging, but very important problem that has not yet been addressed effectively. This paper pro...
