On Distributed Time-Dependent Shortest Paths over Duty-Cycled Wireless Sensor Networks
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...

Secure Continuity for Sensor Networks
Addition of new nodes to a Sensor Network is a fundamental requirement for their continuity operation over time. We analyze the weakening of security due to node capture when addi...
