In Technological world, Wireless sensor networks (WSNs) have achieved a lot of popularity and widely spread in various applications such as military, medical, Industrial, environmental monitoring. In most of the applications, the nodes of WSN are deployed in unreachable areas where the humans cannot intervene. Hence recharging or replacing the battery of nodes is one of constraints in WSN. Also, WSN security is one of the technical challenges. Therefore one must employ various techniques to conserve the energy and detect the malicious nodes in networks to improve the lifetime, reliability and throughput of the WSN. This paper discusses various techniques for improving energy conservation and securing WSNs by mitigating malicious nodes.
