Analysing and Comparing 6LoWPAN, RPL and COAP Protocols for communication between IOT Nodes

Abstract

As one of the greatest significant uses of the Internet of things (IOT), the intelligent household is becoming more and more popular day by day. There are many broken nodes in intelligent household which can rise some possible risk, such as snooping, denial of service and others. The method of design and tool of secure nodes for intelligent household built on IoT technology is presented by this paper, besides giving the hardware model of nodes, the organization of key, the contact authentication of network, the communication of encrypted data, and the alarm based on interruption detection and other security machineries are also given here. The outcomes of simulation display that the planned method can successfully improve the performance of the intelligent household from access protection and transmission message is constructed by a test stage in this paper. Besides it can also display how many packets are losing and how many packets are receiving during the communication of the nodes.
