Wireless Sensor Network (WSN) are in huge demand since last few years, we have seen a wide growth of wireless devices in many applications ranging from agriculture to aviation industry are few of them. It comprises of the number of sensor nodes (SN), which sense the physical phenomena from the environment and send this sensed information to the base station (BS) for further processing. Here, energy of the SN play an important role for lifetime of the overall network and to maintain security during the process of communication between each SNs is also crucial. Considering the aforementioned points, there is need to design a routing algorithm, which reduces the energy consumption as well as maintain the security. In this paper, a brief overview of routing challenges in WSN along with energy efficient cluster-based protocol named LEACH with its vulnerabilities are presented. The primary objective of a cluster-based protocol is to reduce the delay in the system and also consumption of less energy. It achieves scalable routing and energy proficient and fair access for nodes. This protocol has quite a few deficiencies with respect to security, which can be solved by extending it. This paper also highlights improved version of LEACH protocol with its advantages and limitations as compared to the Sec-LEACH protocol. We have compared the LEACH and Sec-LEACH protocols by varying the number of nodes per round. The Sec-LEACH protocol is used to reduce the security attacks from the outsider intruders in a cluster, increases the lifetime of the network, and reduces the number of compromised nodes and energy consumption, thereby improving the overall performance of LEACH protocol.
