Wireless Sensor Network has been one of the most diversified and widely used area and has a vast range of has applications in almost every field. Wireless Sensor Network is a domain with a large number of motes that collects data from the surrounding and after processing, it transfers the data to the sink node through intermediate sensor node after which it is finally transmitted to the base station. With wide range of applications, Wireless Sensor Network comes up with one of the major issues i.e. Energy Consumption. Due to the dense network topology of WSN, the communication range is short which incurs a redundancy in the sensed data. To reduce this redundancy, Data Aggregation and Data Fusion are most effective as it helps in saving both data and energy. This paper proposes a Secure and energy efficient architecture that takes account of the constraints of sensor networks. A hierarchical network topology is formed that enables end-to-end communication between sensor nodes and the architecture also supports the detection and isolation of malicious nodes. Moreover, security issues of a wireless sensor network are also a major concern and so, we aim to design a secured architecture for reliable and safe data communication. To make the system energy efficient, Low-Energy Adaptive Clustering Hierarchy (LEACH) algorithm has been used. Algorithm also helps in the secure transmission of data and also conserves energy. By doing simulations in NS2 we found that it saves energy and hence enhances the lifetime of a mote.
