A Wireless Sensor Network (WSN) is a wireless network consisting of spatially distributed autonomous devices that use sensor nodes to monitor physical or environmental conditions. These distributed autonomous devices, or nodes, combine with routers and a gateway to create a typical WSN system. The distributed sensor nodes communicate wirelessly to a central gateway, which provides a connection to the wired world where the users can collect, process, analyze, and present their measurement data. Due to the broadcast nature of the transmission media they use, sensor networks are vulnerable to various security attacks, such as eavesdropping, jamming and node capture attacks.
