Wireless sensor network is a combination of tiny devices called as sensor nodes which have
computing, sensing and processing capabilities. As WSN are deployed in hostile …

Handling the security in Wireless Sensor Networks (WSNs) requires cryptographic
mechanisms to detect faulty and unstable nodes that lead to the inactivity of network during …

Surveillance wireless sensor networks (WSNs) are highly vulnerable to the failure of the
base station (BS) because attackers can easily render the network useless for relatively long …

Abstract Wireless Sensor Network (WSN) is widely used in many life applications. WSN has
many limitations in terms of energy and battery lifetime that puts constrains in implementing …

Abstract Key management in Wireless Sensor Network (WSN) is a complex task due to its
nature of environment, limited resources and open communication channel. In addition …

Wireless Sensor Networks usually consists of a large number of tiny sensors with limited
computation capability, memory space, power resource and communications capabilities …
