Network architecture of Internet of things based on mobile gateway

Abstract

The invention belongs to the technical field of an Internet of things and relates to a network architecture of an Internet of things based on a mobile gateway. The network architecture is characterized by comprising a wireless sensor network, an Internet and a mobile gateway, wherein the wireless sensor network is composed of an intelligent object with a wireless communication module; the mobile gateway is composed of an intelligent external device and a mobile terminal which are respectively provided with a wireless communication module; the wireless sensor network carries out networking according to a certain standard (such as IEEE 802.15.4 standard); the intelligent object is composed of a sensor, a controller and a wireless communication module, and the state information of the intelligent object can be sensed by the sensor or the state of the intelligent object is controlled by the controller; the mobile gateway can acquires the state information of the intelligent object in the sensor network through the intelligent external device, and upload the state information to the Internet through the mobile terminal, thereby realizing information aggregation; and the mobile gateway can also transmit the information of the Internet to the controller of the intelligent object through the intelligent external device, thereby realizing remote control, state change and the like of the intelligent object.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things and relates to a novel network architecture of the Internet of Things. Background technique [0002] The rapid development of modern information technology has made the Internet a huge virtual world, and people's lifestyles have also undergone tremendous changes. However, with the rapid development of mobile communication networks, wireless sensor networks and RFID technologies, people urgently need a The "real" network world enables people to "perceive" and "control" all things in the world, realize the interconnection of things and form a "smart" earth. These have contributed to the emergence of the Internet of Things. From President Obama's "Smart Earth" to Premier Wen Jiabao's "Sensing China", the Internet of Things has also fully landed in China, and has even been raised to the height of the national development strategy. The Internet of Things is to connect "things" with the...
