Abstract. Wireless Mesh Networks are an increasingly common technology providing connectivity in many communities, particularly where Internet access is unavailable or restricted v...
This paper presents a sentry-based approach to power management in wireless sensor networks for applications such as intruder detection and tracking. To minimize average power cons...
Wireless Sensor Networks (WSN) security is an important issue which has been investigated by researchers for few years. The most fundamental security problem in WSN is key manageme...
—The pervasive distribution of digital images triggers an emergent need of authenticating degraded images by lossy compression and transmission. This paper proposes a robust cont...
Sensor networks have recently gained popularity for a wide spectrum of applications. When performing monitoring tasks in hostile environments, security requirements become critical...
