Sensors’ locations play a critical role in many sensor network applications. A number of techniques have been proposed recently to discover the locations of regular sensors base...
Distributed wireless sensor networks have problems on detecting and preventing malicious nodes, which always bring destructive threats and compromise multiple sensor nodes. Theref...
Collaborative spectrum sensing in cognitive radio networks has been proposed as an efficient way to improve the performance of primary users detection. In collaborative spectrum se...
This paper focuses on defending against compromised nodes’ dropping of legitimate reports and investigates the misbehavior of a maliciously packet-dropping node in sensor networ...
Most of the routing protocols in wireless ad hoc networks, such as DSR, assume nodes are trustworthy and cooperative. This assumption renders wireless ad hoc networks vulnerable to...
