Cooperative Boundary Detection for Spectrum Sensing Using Dedicated Wireless Sensor Networks
Abstract—Spectrum sensing is one of the key enabling technologies in Cognitive Radio Networks (CRNs). In CRNs, secondary users (SUs) are allowed to exploit the spectrum opportuni...

Lifetime Security Improvement in Wireless Sensor Network Using Queue-Based Techniques
A wireless sensor network (WSN) is envisioned as a cluster of tiny power-constrained devices with functions of sensing and communications. Sensors closer to a sink node have a larg...

Multiratecast in Wireless Fault Tolerant Sensor and Actuator Networks
We study the multicast problem in wireless sensor networks, where the source can send data to a fixed number of destinations (actuators) at a different rate (multiratecast). A typi...

Model-Based Design Exploration of Wireless Sensor Node Lifetimes
This paper presents two lifetime models that describe two of the most common modes of operation of sensor nodes today, triggerdriven and duty-cycle driven. The models use a set of ...
