Wireless Sensor Networks: Architecture, Applications and Protocols
Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-free wireless network to track physical or environmental conditions, such as temperature, sound, vibration, pressure, movement or pollutants, and to transmit data through the network to a main location or sink where data can be monitored and analyzed. Wireless sensor network are growing continuously and it can be widely used in many critical applications like, military surveillance, or medical applications, applications so the need of the security becomes vital. Security threats are impending on wireless sensors because of its open nature of communication. The highly sensitive nature of collected information makes security in these special networks a crucial concern. As attacks to any part of the hardware or software may give significant damages to these networks hence it is important to focus more on wireless sensors Network security.
