[Abstract]:Low speed wireless personal area network (LWPAN) is widely used in many fields, such as industrial control, commercial detection, fine agriculture, smart home and so on. As the main supporting technology of low speed wireless personal area network communication system, wireless transmission protocol is the key to exchange information between devices in the network, which ensures the security and stability of wireless terminal data transmission. At present, wireless transmission protocols in low-speed wireless personal area networks face many security threats, such as power consumption, portability, network topology and device information eavesdropping. Based on IEEE802.15.4 standard and ZigBee protocol specification, a high reliable wireless transmission protocol with high portability is implemented in this paper. The protocol can effectively prevent malicious devices from attacking and prolong the network life cycle. Wireless transport protocols include physical layer MAC layer, network layer and application layer. The MAC layer has the functions of channel scanning, device association and data request. This paper, referring to the ZigBee security specification, designs the MAC layer security mechanism and implements the MAC layer frame protection on the basis of stable and reliable data transmission. Avoid the attack of malicious devices, and increase the security of the network. The network layer supports the establishment of the network, mainly responsible for the discovery and maintenance of routing. In this paper, the hierarchical tree routing AODV routing, energy balanced routing and other routing strategies are studied. On this basis, the energy efficient directional control tree routing EDTR is designed and simulated, which equalizes the energy consumption of the equipment in the network and prolongs the lifetime of the network. The application layer can write different application programs according to the actual application. This paper realizes the encryption of application data in application layer based on AES algorithm, prevents useful information from being stolen in the network, and further increases the security of the network. In this paper, the network simulation software NS2 is used to simulate and analyze the routing strategy of the wireless transport protocol NWK layer in this paper, and the AODV routing is compared and analyzed. The energy balanced routing and the energy efficient directed control tree routing (EDTR) designed in this paper have the characteristics of low power consumption and low delay in EDTR routing strategy. In addition, this paper uses CC2530 as the core hardware platform to verify the security mechanism of MAC layer and application layer, and draws the conclusion that the improved wireless transmission protocol can avoid malicious device attack and prevent useful information from being stolen in the network.
