Wireless Sensor Network (WSN) comprises of several tiny devices, low-cost, low-power and sensor nodes. This node has distinctive nature unlike from other networks. It includes a huge amount of small sensing devices with some limitation in energy, computation, and communication capabilities. These sensing devices are designed for specific applications, and they interact directly with their physical environments. The applications of WSNs are abundant; many of them are even security critical such as military or security applications. However, strong security practice should be deployed to secure the network from various attacks.
