摘要
针对传统的物联网中协议转换网关仅考虑协议数据间的转换,当物联子网中的节点网络环境发生变化时难以有效地实现数据通路等问题,提出一种在通信辅助网关协助下的物联网通信体系结构:以IPv6网关组成骨干网络,以通信辅助网关实现区域网络与IPv6网络协议互转和通信,区域网络内部使用ZigBee、Bluetooth等协议短距传输。最后,对协议报文格式进行了简化设计,通过Ptolemy II建模环境搭建通信模型,仿真结果表明:利用通信辅助网关的协助,本文方案在存在丢包情况下,依然可以通过重发实现网络数据传输,确保IPv6网络与物联子网的互联互通。
In view of the fact that traditional protocol conversion gateway in the Internet of things （loT）just implements the conversion between protocol data, when the network environment changes, it is difficult to implement the data path effectively. An IoT communication architecture with the assist tance of the communication auxiliary gateway is proposed. The backbone network is composed of the IPv6 gateway, the communication auxiliary gateway is used to realize the protocol interconversion and communication between the regional network and the IPv6 network, and the ZigBee, Bluetooth and other protocols axe used for the short distance transmission within the regional network. Finally, a simplified protocol message format is designed, and the architecture model is built based on the Ptolemy II modeling environment. The simulation results show that the interconnection between the IPv6 network and the subnet of IoT can be realized more effectively with the assistance of the communication auxiliary gateway, even if under the situation of packages missed.
