Embodiment 1

[0049] On the Windows operating system configured with at least two Wi-Fi 802.11 network adapters (Network Adapter, NA), install the WLAN-over-MANET converged network on-demand routing driver designed in the form of Windows NDIS IM driver (denoted as WoM driver) . Through simple configuration, one of the two Wi-Fi 802.11 network adapters is used to connect to the local WLAN, works in infrastructure mode, and provides WLAN AP services (the same effect can also be achieved by connecting to a dedicated AP through a wired network adapter); the other It is used to connect MANET and work in IBSS mode. With the support of the WoM driver, the system can perform the data packet routing and forwarding functions of the WLAN-over-MANET converged network gateway (MAR). When working in detail, the unique identification of the gateway (MAR) in MANET is designated as the IP address allocated on the MANET network adapter.

[0050] The WLAN-over-MANET converged network routing driver WoM desi...

Embodiment 2

[0052] The best implementation mode of the present invention is:

[0053] WLAN-over-MANET converged network Windows on-demand routing gateway (MAR) and WoM driver system architecture schematic diagram shown in Figure 3, in which the framework of Figure 3-(2) uses a Wi-Fi network adapter with AP function to access WLAN, Figure 3 3-(1) uses a wired network adapter to connect to a dedicated AP to access the WLAN. As an NDIS IM driver, WoM works between the existing TCP / IP protocol stack of the upper Windows system and the lower-layer network card driver, and binds multiple network card drivers for connecting to WLAN, MANET and other networks respectively for the lower-level Windows system. Different virtual network card adapters, and their working methods are completely transparent to the upper layer driver. WoM uses NDIS-encapsulated system calls (in Ndis XXX Form naming, such as NdisSend, XXX is a wildcard for the specific function name) communicate with the upper and lowe...

Abstract

The invention discloses a demand routing gateway of an Ad hoc fusion network and a driver design method thereof. In the method disclosed by the invention, a demand routing driver of a WLAN (Wireless Local Area Network)-over-MANET (Mobile Ad hoc Network) fusion network designed by a Windows NDIS (Network Driver Interface Standard) interlayer micro-port driving mode is installed on a Windows operating system with multiple wireless network adapters; a Wi-Fi802.11 network adapter is selected to be used for connecting a local WLAN and provides WLANAP service; another wireless network adapter is simultaneously selected and used for connecting an MANET; and under the support of the demand routing driver of the WLAN-over-MANET fusion network, the system can execute the data message routing and rebroadcasting functions of a WLAN-over-MANET fusion network gateway. By means of the method disclosed by the invention, the high-efficiency demand routing driver of the fusion network is established in the Windows operating system, and the demand routing driver is used as a basis to form a key equipment MAR (Memory Address Register) of the fusion network, thereby providing a beneficial path for establishing an entity test and application platform of the WLAN-over-MANET fusion network.

Description

[0001] technical field [0002] The invention relates to a converged network Windows on-demand routing gateway supporting WLAN communication across MANET (referred to as WLAN-over-MANET) and a driving design method thereof. Background technique [0003] Mobile Ad hoc Network (MANET) is an autonomous network system composed of a series of nodes with mobile wireless transceiver capabilities, and has special capabilities such as self-organizing networking and multi-hop communication. Despite the characteristics of frequent topology changes, unstable wireless channels, limited link bandwidth, and tight computing and storage resources, the MANET network can work normally without relying on any fixed infrastructure, and has good mobility, self-organization and Invulnerability, convenient deployment and low cost compared with traditional wired networks, have broad application prospects in military battlefields, disaster relief, people's livelihood, business and other fields, th...
