Abstract

A protocol conversion wireless gateway with the content as the center is used as an internet communication interface of a backbone network and a wireless sensor network for achieving the functions of protocol conversion and storage forwarding and achieving data communication of two networks based on content modes. The protocol conversion wireless gateway is composed of an ARM plate which is connected with the backbone network in a wired mode, receives data packages sent by the backbone network and is used for conducting analysis and protocol conversion on the data packages, and a sink node which is connected with the wireless sensor network in a wired mode and is used as an aggregation node. The ARM plate is in data communication with the sink node through a usb port. The ARM plate is provided with a usb port monitoring unit, a ccnb unit and a ccnd unit which are in series connection. The sink node is not involved in analysis processing of the data packages and is only in charge of forwarding the data packages. The wireless gateway enables the operation steps for achieving internet communication of the two networks to be simple and easy, data conversion operation is achieved on a network layer, the system overhead of data package transmission and analysis is reduced, and the high efficiency of data communication is kept.

Description

technical field [0001] The present invention relates to a new network architecture and its working method, to be precise, it relates to a content-centered protocol conversion wireless gateway and its communication method, belonging to the Internet of Things, next-generation network or information-centered network technology field. Background technique [0002] Since the birth of the Internet, TCP / IP is currently the most successful and effective communication solution, and it is also the communication protocol supporting the current Internet architecture. The problem TCP / IP solves is end-to-end communication between entities; however, the protocol's method of distributing content can easily congest and overload the network. [0003] In order to solve the large-scale content transmission and distribution requirements faced by the future Internet, the Future Network Architecture Project Team of the National Science Foundation NSF (National Science Foundation) proposed the net...
