Abstract

In order to adapt to the characteristics of multi network convergence of IOT, this paper sorts out and summarizes the development status and existing problems of Internet of things (IOT) and wireless sensor network (WSN) as well as the key points for future research. Based on the existing research, the wireless sensor topology SORCA protocol is improved, and an energy saving intrusion tolerant network topology SORCA-W generation method is proposed, which realizes the interconnection of multiple sensor networks. Firstly, according to the location of nodes, the network is divided into topology network composed of hexagonal units. Through adding different network nodes collection summary, the neighbor table is judged and modified, and the name of the network is added. As a result, it is concluded that a plurality of wireless sensor networks can be connected for communication, which realizes the multi network integration of perception layer of Internet of things

Highlights

The Internet of Things (IoT), an integration of existing networks [1,2], is a ubiquitous network built on the Internet
The major problems and concerns are as follows: firstly, the existing security technologies fail to meet the requirement of multi-network integration of the IoT; secondly, how to avoid the impact of the newly-added nodes on other networks; thirdly, how to identify different network nodes and how to cooperate; fourthly, whether there are security risks during the message transmission and how to ensure the security of messages in reposting and how to repost messages of different networks [5,6]
How to design a new topology and routing protocol to solve the security problems of wireless sensor networks (WSNs) in the IoT is of great significance

Summary

Introduction

The IoT, an integration of existing networks [1,2], is a ubiquitous network built on the Internet It is growing along with the progress of various networks, especially the improvement on the process of the wireless sensor originals. Different perception nodes can perceive the information that people need and transfer it to the terminal applications timely and stably, which is a further expansion of the original network and a critical material foundation for the development of the IoT [4]. IoT is an expansion of the existing network and new problems, as mentioned above, will emerge in the process of network integration. These problems will directly affect the security and stability of the network. How to design a new topology and routing protocol to solve the security problems of WSNs in the IoT is of great significance
