Spatial query execution is an essential functionality of a sensor network, where a query gathers sensor data within a specific geographic region. Redundancy within a sensor networ...
In cognitive radio networks (CRNs), spectrum sensing is key to opportunistic spectrum access while preventing any unacceptable interference to primary users’ communications. Alt...
Abstract—One of the reasons that the research of intrusion detection in wireless sensor networks has not advanced significantly is that the concept of “intrusion” is not cle...

One vision of an opportunistic sensor network (OSN) uses sensor access points (SAPs) to assign mobile sensors with sensing tasks submitted by applications that could be running any...
In this paper, we study end-to-end performance characteristics of S-MAC, an energy-aware medium access control (MAC) protocol for wireless sensor networks (WSN). WSNs are composed...
