Addressing method for sensing service application oriented wireless sensor network

Abstract

The invention relates to an addressing method for a sensing service application oriented wireless sensor network, comprising the steps as follows: step A. a sensor node uploads sensing data to a sink node; step B. the sink node processes the uploaded sensing data to form one or more sensing service applications and stores the sensing service applications at the sink node; and step C. the sensing service applications are distributed with IP addresses. The addressing method has the beneficial effects that the addressing mode of the invention preferably accords with the network characteristic that the sensor network is oriented to data. Simultaneously, a user can directly obtain sensing service applications provided by a WSN (Wireless Sensor Network) by accessing the Internet through configuring IP addresses to sensing service applications, thus being favor of popularization and generalization of the WSN (Wireless Sensor Network).

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network (WSN, wireless sensor network), in particular, it is an addressing and addressing technology that integrates a wireless sensor network and the Internet (Internet). Background technique [0002] Wireless sensor network (WSN) is a distributed intelligent network composed of a large number of tiny sensor nodes with communication and computing capabilities deployed in the active area. It can be formed by self-organization and can independently complete specified tasks according to the environment. [0003] In a broad sense, the definition of sensing business application is a set of ordered collections of processed sensing data that can meet the specific needs of users, and the data it contains are independently collected by multiple sensor nodes. In a narrow sense, the business application is a service similar to the application process in the host in the Internet formed after a group ...

Problems solved by technology

Even if WSN adopts a data fusion strategy to improve network efficiency, its focus is usually on the access and layout of nodes, and there is no systematic integration and processing of data based on data content in terms of function and logic.

[0005] 2. The existing addressing and addressing methods of wireless sensor networks are not conducive to the integration of wireless sensor networks and the Internet

Wireless sensor network is a network that interacts with the actual environment. At present, the composite network combining wireless sensor network and Internet has become a general trend. It will become very necessary for users to access efficient and reliable data of wireless sensor network through Internet. The addressing method used by the wireless sensor network is different from the IP addressing method used by the Internet. Users in the Internet cannot directly use the IP addressing method to access the WSN.
