In Wireless Sensor Networks (WSNs) large number of sensor nodes is deployed in the required region for getting the information about the environment related to a particular application. These sensor nodes have limited battery source in most of the cases, therefore extending network lifetime in WSNs becomes one of the major challenge. WSNs have distributed nature, multi-hop data forwarding, and open wireless medium they are vulnerable to security attacks at various levels. For routing in WSNs hierarchical clustering based routing protocol LEACH is a successful protocol which utilizes energy of sensor nodes evenly. However, there exist some flaws in this protocol which can attract intruders and can cause serious damage to the network. In this paper, a secured version of energy-aware clustering approach is proposed to minimize the risk of attacks by the intruders either from outside or inside of the network. Furthermore, we propose a clustering approach in which the overall load of cluster head is balanced in each round and the intruders are detected before transmission of data to the base station so that information are safe. Simulation and analysis result shows a significant improvement in proposed work over other protocols like DEEC, LEACH in terms of various parameters i.e. lifetime of network, nodes death, network connectivity.
