Detection of attacks in IoT based on ontology using SPARQL

Nowadays, the concept of Internet of Things (IoT) has been manifested into reality with the help of latest developments or transformations in hardware circuitry, devices and protocols. IoT is such a diversified field in which a lot of challenges are faced during implementations of IoT applications including smart cities, smart homes, industrial sectors etc. The current scenario is highly demanding for deployment of smart sensors into existing applications to deliver a fully automated system. The major issue faced by IoT's existing system is security issue. In this paper, various attacks in IoT systems has discussed and focuses on ontology based model to deal with various attacks.
