—For a wireless network with ¢ nodes distributed in an area £ , with ¢ source-destination pairs communicating with each other at some common rate, the hierarchical cooperation...
Abstract—We revisit the shortest path problem in asynchronous duty-cycled wireless sensor networks, which exhibit time-dependent features. We model the time-varying link cost and...
Key distribution is one of the most challenging security issues in wireless sensor networks where sensor nodes are randomly scattered over a hostile territory. In such a sensor dep...
Abstract— In many energy-rechargeable wireless sensor networks, sensor nodes must both sense data from the environment, and cooperatively forward sensed data to data sinks. Both ...

Abstract—In this paper we address the problem of energyefficient event detection in wireless sensor networks (WSNs). Duty cycling is a fundamental approach to conserving energy i...
