Wireless Sensor Networks (WSNs) consisting of various sensor nodes which are distributed autonomously over the network. These sensor nodes can sense, measure and collect information from the environment. Every sensor node is having its own energy source and it is non-rechargeable battery. Therefore, the network must be designed in such a way that they can be able to make use of energy source in an efficient manner. These information are sometime very confidential and need to be secured e.g. in military applications. So, the security model of the network must be efficient enough to provide security in the same.
