ABSTRACT Wireless Sensor Networks (WSNs) have been employed in many real-world
applications that greatly improve our life. The ubiquitous WSNs make security a prime issue …

In the past few years, research interest has been increased towards wireless sensor
networks (WSNs) and their application in both the military and civil domains. To support …

Building a secure routing protocol in WSN is not trivial process. Thee are two main types of
security attacks against WSNs: active and passive. WSN as a new category of computer …

In wireless sensor networks, clustering expedites many desirable functions such as load
balancing, energy savings, and distributed key management. For secure clustering, it is very …

Abstract A Wireless Sensor Network (WSN) is an Ad-hoc network populated by small hand-
held commodity devices, running on batteries called stations or sensors. These sensors are …

In wireless sensor networks, clustering sensor nodes into small groups is an effective
technique to achieve scalability, self-organization, power saving, channel access, routing …
