Abstract
the fusion of cellular network and wireless sensor network is the key research problem of Internet of Things (IoT) technology at present. The design and implementation of wireless sensor cellular network based on Android platform is mainly studied. Firstly, wireless sensor network and cellular network, Android platform, cellular network and Wireless Sensor Network (WSN) fusion strategy, and Wireless Sensor Network (WSN) gateway platform are introduced. Then related functions are introduced, mainly including terminal registration management, connection management, authentication management, terminal fault management, and communication message design on the gateway and sensor network side. Finally, related functional tests are conducted. The results show that the designed application layer gateway system can connect the sensor network with the cellular network. Time Division-Synchronization Code Division Multiple Access (TD-SCDMA) and cellular network covers the whole world, while cellular network has been interconnected with the Internet through Access Network Technologies such as General Packet Radio Service (GPRS), The Fourth Generation of Mobile Phone Mobile Communication Technology Standards (4G) and Long Term Evolution (LTE), thus enabling the sensor network to access the Internet anytime and anywhere
Highlights
Wireless sensor network is a kind of information acquisition and processing technology that can realize signal acquisition, processing and transmission
With the advent of the Internet of Things era, wireless sensor networks are increasingly applied extensively, and it has gradually penetrated into all areas of human life and production and has attracted the attention of people in the industry
The basic idea is to design a special module that can communicate with the wireless sensor network and communicate with the cellular network of the mobile communication at the same time, which acts as a bridge
Summary
Wireless sensor network is a kind of information acquisition and processing technology that can realize signal acquisition, processing and transmission. A multihop self-organizing network system can be formed between these nodes through wireless communication Through this network system, the wireless sensor node sends data to the routing node through the wireless data transmission after the sensor collects the data. The first part is a large number of sensor nodes that are randomly distributed, energy-constrained and resource-constrained These nodes have sensing capabilities and collect data through sensors and transmit data wirelessly to routing nodes or coordinating nodes. The basic idea is to design a special module that can communicate with the wireless sensor network and communicate with the cellular network of the mobile communication at the same time, which acts as a bridge This module can be either in the Sink node of the sensor network or as a separate gateway module.
