Problems solved by technology

Obviously, in this way, the sensor nodes must send updated data to the proxy gateway 11 at a high frequency cycle to ensure the real-time performance of the database, which will inevitably consume the limited energy of the sensor nodes faster, resulting in a reduction in its survival time
[0005] In addition, the above-mentioned proxy method also has the following defects: a proxy gateway is usually dedicated to a specific task or a specific protocol, therefore, a specific application requires

Example Embodiment

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Figure 4 It is a schematic diagram of the structure of the sensor network interconnection system provided by the present invention. It includes two independent sensor networks 10A, 10B, an IP network system 12, and sensor networks 10A, 10B respectively connected to the IP network system 12 through respective access gateways 15A, 15B To form a sensor network system in a larger sense, the client 121 (15c) can be used as an access node or a management node to perform an operation on the sensor nodes in the sensor networks 10A and 10B through the IP network system 12 and the access gateways 15A and 15B. Access, configuration.

[0021]Generally speaking, the sensor node is usually a miniature embedded system. Due to the limited battery power it carries, its processing capacity, storage capacity and communication capacity are relatively weak...

Abstract

The invention provides a sensor network data access method, and an access gateway and a system thereof. The sensor networks are linked via gateways and IP network systems to support access to sensor network data. The access method comprises the following steps: (a) storing target access equipment information in a gateway; (b) searching the target access equipment information by the gateway when the gateway starts routing the sensor data from a sensor network linked with the gateway according to target node information of the sensor data; (c) carrying out IP data encapsulation of the sensor data with the obtained target access equipment information and sending to target access equipment via an IP network; and (d) decapsulating the received IP data packet by the target access equipment.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data communication process used by a sensor network (Sensor Network). Background technique [0002] With the continuous development and improvement of sensor technology, wireless communication technology and computing technology, various sensor networks will spread all over our living environment. The sensor network can measure the parameter value of the observed object in a given area, detect the event of interest and estimate related parameters, classify and identify the observed object, locate and track the observed object, etc., and has broad application prospects. , Widely used in national defense and military, security and anti-terrorism, environmental monitoring, traffic management, medical and health, disaster relief and industrial manufacturing and other fields. [0003] Usually, as a sensor network system of an isolated network, it has a relatively inde...
