基于WebSocket的网络设备自发现机制

摘要

针对越来越多的电子设备及其之上的资源处于分散、孤立、难管理的状态,在分析研究国内外多种互联互通技术标准的基础上,提出了基于WebSocket协议的网络设备自发现机制,并定义了设备自动发现协议ADDP,即Auto DeviceDetecting Protocol.ADDP机制充分利用WebSocket全双工、实时性的通信特点,通过建立WebSocket长连接的方式,使接入互联网中的各种智能电子设备之间能够相互发现,并组成一种新网络,即个人域互联网络,在该网络中智能设备之间能够互相通信,进而可以实现资源共享和协同服务.实验结果表明:ADDP机制在设备自发现方面具有较广的发现范围和较高的发现效率,从而验证了ADDP机制的正确性和可行性.%The number of electronic devices has increased rapidly,however,these devices and their corresponding resource are dispersed,isolated,difficult to manage,to address this issue,a WebSocket based a auto-detecting mechanism of network devices is proposed.Firstly,interconnection technical criteria at home and abroad are analyzed.Next,Auto Device Detecting Protocol mechanism (ADDP) is defined.ADDP mechanism makes full use of WebSocket duplex,real-time communication characteristic,It can set up WebSocket long connection so that access to the Internet in various smart electronic devices can be discovered each other,and a new network is built,namely personal domains interconnected network.In the network intelligent devices can communicate with each other,and realize resource sharing and collaboration services.The mechanism achieves interconnection a-mong smart devices in the personal domains interconnected network.The simulation experiments show that this mechanism has a wider scope of discovery and higher discovery efficiency,which proves the correctness and feasibility of the ADDP mechanism.
