Security of Wireless sensor network (WSN) turn out to be a very important issue with the rapid development of WSN that is vulnerable to a wide range of attacks due to deployment in the hostile environment and having limited resources. Clustered Networks have been proposed to reduce the power consumption in sensor networks. LEACH is a clustering based protocol that lessens energy dissipation in ...

Wireless Sensor Networks (WSNs) are defined as dynamic, self-deployed, highly constrained structured network. The WSN is a special kind of network which consists of large number of sensors and minimum one base station. Main difference between the WSN and the traditional wireless networks is that sensors are extremely sensitive to energy consumption. Energy saving and load balancing are the cruc...
