Research Of ZigBee Multi-level Routing Algorithms And Security Mechanisms

With the development of information technology, communications technology and microelectronics technology, Internet of Things technology and its applications have high-speed development. In daily life, people have been unable to leave the wireless network, and in the future days, Internet of Things will also gradually into the thousands, and become part of people’s life. Internet of Things, the vast subject and the knowledge integration high hot research field, has become the focus of people’s attention. ZigBee technology, as an important branch of this field, have drawn the attention of the international scientific research units and civil organizations, and develop very quickly in the last few years. Its safety and energy efficiency became one of the most problems that many people study. As a wireless transmission technology, ZigBee network is fully exposed in an open environment which can easily be eavesdropping attacks by hackers. The ZigBee network users wirelessly access the network and wirelessly transmit personal information to authenticate. In this open interface environment, in order to prevent a malicious user unauthorized access to the network, network resources, steal user information we must choose a safe and reliable authentication scheme, especially for e-commerce, the military-industrial complex communication services, safety is more important, or it may cause irreparable loss.Current research on wireless network security technology is mainly focused on the study of some of the key technologies of information security, these key technologies including authentication, key exchange, cryptography, security architecture technology. More mature technology is used to solve the issue of information security in the common network of wireless broadband access networks, mobile communication networks, and wireless local area network. The overall security system of wireless network security technology has gradually formed in our country.ZigBee technology is a typical representative of one of the emerging wireless LAN. Its main feature is the low-power, short-range, low-rate, high-density, form networks freely, which is its unique excellent place. It is particularly applicable in wireless monitoring LAN. In the future, it will be the complement of the Internet extends to every corner of the domestic, industrial, military. ZigBee technology security is the most significance; it is the basis for the ZigBee large scale applications. Because ZigBee nodes generally have low energy, slow, poor storage capacity characteristics, most of the security algorithms cannot be directly applied, so it is necessary to improve or designed specifically for it.In this paper, the current wireless network security mechanism is studied, all kinds of security schemes are analyzed in detail, study the authentication and key exchange technology, routing security system, analysis the advantages and disadvantages of the existing security routing algorithm, put forward the improved scheme, design a new security routing algorithm, in order to be able to solve the ZigBee wireless network security issues and energy efficiency issues.Finally, this paper proposed low-power multi-level routing algorithm based on the credibility of the model and energy classification, by means of NS2Network simulation software, the ZigBee routing protocol simulation experiment was carried out to verify the safety and reliability of the new algorithm. In the final analysis the design process of ZigBee physics experiment platform, and in the new algorithm designed physics experiment platform in practice, to further verify security of the algorithm.
