Design of Secure Communication Methodologies for WSN Assisted IoT Applications

Wireless Sensor Networks (WSNs) is main IoT module that gathers data from the environment and sends it to the destinations. The IOT may contain a broad variety of devices. Interconnecting several singly operating IoT devices via internet presents various issues, security that is remains a major concern given the large and frequently unknown audience. For resource-constrained nodes, most known techniques are very recursive. The sensor node’s resource will be severely shortened, compromising communication and security. However, the opponents' behaviour in WSNs has never been studied. The IoT network and its applications need a sophisticated security architecture to protect both gateway and sensor nodes from attacks. A secure communication system is the major goal of this work.
