Design of IOT Gateway System Based on WMMP-T Protocol

Abstract

The coexistence of various network protocol standards at present creates a huge barrier against network interconnection and interoperability. This paper proposes an IOT gateway system to implement various heterogeneous networks interconnection and interworking. The multi-protocol conversion gateway system is developed on top of the WMMP framework to integrate heterogeneous networks and incorporates a semantic model of an IOT software system. And then the protocol conversion method is designed on the basis of the protocol driver template, which is configurable for different communication protocols. The gateway communication process is implemented to report and transmit data and forward command to the bottom layer devices. As a result, the analysis test results show that dynamic protocol conversion mechanism of the gateway provides a good operating environment for different service functions for stable, scalable and real-time remote control system.

Multi-interface Gateway Protocol Conversion Method for Nearspace-air-vehicle-ground Dedicated Network

“…For example, Yan Lianlong analyzed some key technologies for building embedded gateways. Based on the analysis of some embedded technologies, he proposed a design scheme for embedded gateways and realized the protocol conversion between CAN, RS-485 and the Internet, and gives a concrete realization [5].…”
