Design and Development of Context Aware Secure Routing Arch in IoT

In our research, we merge the fundamental concept of the context awareness computing model in the Internet of Things and the routing protocol of the wireless sensor network, and propose a new routing protocol CRP (Context-Based Routing Protocol) for the Internet of Things, based on context-awareness which belongs to the key technologies of Internet of Things. Furthermore, our work describes the details on the protocol in the workflow, data structure and quantitative algorithm, context decision and reasoning algorithm and so on. It is also proposed in the work, a low complexity cryptographic algorithm for IoT and its attack detection analysis. Finally, the simulation is given to analyze the work performance of the protocol CRP. Theoretical analysis and experiment verify that CRP has higher energy efficiency and a longer lifetime than the congeneric protocols.
