OID (object identifier) coding based wireless sensing network equipment addressing method

Abstract

The invention discloses an OID (object identifier) coding based wireless sensing network equipment addressing method which is used for addressing according to address identifiers of equipment. The address identifiers of the equipment include enterprise object identifiers, equipment codes, wireless sensing network address codes, subscriber packet identifiers and subscriber set private secret keys. The OID coding based wireless sensing network equipment addressing method includes judging whether network information is unicast information or not according to wireless sensing network address codes in equipment address identifiers carried in the network information, and judging whether the network information is broadcast or multicast information or not according to subscriber packet identifiers in the equipment address identifiers carried in the network information, and meanwhile, acquiring public secret keys and private secret keys for broadcast, multicast and unicast by combining target identifier codes and encrypting random numbers. By the OID coding based wireless sensing network equipment addressing method, convenience in addressing wireless sensing network equipment is greatly improved, multicast function is enhanced, and network safety is improved greatly.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a method and device for addressing wireless sensor network equipment based on OID coding. The method can be used for unified identification and communication addressing of wireless sensor network equipment, while ensuring the uniqueness of wireless sensor network equipment identification, and at the same time ensuring the reliability of wireless sensor network equipment communication with the minimum communication overhead. Security and flexibility. Background technique [0002] Object Identifier (OID) is an identifier used to identify the unique identity of an object in a network communication or information processing system, and is the ID card of an "object". Through OID, we can get the relevant characteristics and information of the object. Once an object's OID is registered, it is permanently valid worldwide. OID has been widely used in computer networks,...

Problems solved by technology

[0004] With the development of the Internet of Things industry, the demand for Wireless Sensor Network (WSN) products is increasing, but the existing wireless sensor network devices still use traditional coding methods or Therefore, these coding and addressing methods cannot adapt to the application characteristics of wireless sensor networks, resulting in problems such as data redundancy, low communication efficiency, and poor security.

[0005] For example, most of the products based on the ZigBee protocol widely used at present are a set of encoding methods formulated by the manufacturers themselves. recognized

[0006] On the other hand, the identification and addressing methods of some wireless sensor network equipment adopt the protocol standard of IPv6. Although this method can guarantee the uniqueness of equipment identification and can be recognized by international organizations, the complexity of its communication data, The efficiency of wireless sensor network communication is greatly reduced

Applying IPv6 technology to wireless sensor networks has the disadvantages of large IPv6 packets, heavy packet header load, complex address translation, easy to cause packet flooding, high resource requirements for routing methods, and does not support multicast function and network configuration. Complicated and other defects

[0007] Moreover, other types of encoding and addressing methods cannot guarantee the global uniqueness of device identification
