Wireless ad hoc network composition method and wireless ad hoc network system

Abstract

The invention provides a wireless ad hoc network construction method and a wireless ad hoc network system. The method for forming a wireless ad hoc network according to the present invention includes: a first step: in each compartment of a rail transit vehicle, use a vehicle-mounted server or a vehicle-mounted network switch dedicated to the compartment to respectively connect and arrange in the compartment in a wired connection Two wireless network bridges at the head and tail of the car to form the wireless networking unit of the car; the second step: use the wireless networking unit of each car in the rail transit vehicle to perform wireless communication to form a total Internet network.

Description

Technical field [0001] The present invention relates to a wireless self-network configuration method and a wireless self-network system constructed by means of a wireless self-network configuration method. Background technique [0002] With the development of mobile Internet, Internet access is a universal demand, anytime, anywhere. Adapting to this need, providing WiFi access services in the rail transit vehicle, meeting the need for passengers travel wireless Internet access is an inevitable trend. [0003] Providing rail transit vehicles WiFi service requires connection to the entire train, building a vehicle network environment provides a local area network and Internet services, and has a rail transit vehicle that does not deploy inter-vehicle interconnected wired network system, because there is no reserved network installation position and cross The cost of the car installation interface, the cost of adding wired mode networks is high and not easy to implement; using the t...

Problems solved by technology

[0003] To provide Wi-Fi services for rail transit vehicles, it is necessary to connect the entire train to build a network environment for the entire train to provide local area network and Internet services for passengers. For rail transit vehicles that have not deployed a wired network system for inter-car interconnection at the factory, there is no reserved network installation location and cross-connection on the train. It is expensive and difficult to implement the interface installed in the carriage, and it is difficult to implement the addition of a wired network; the traditional Mesh wireless networking solution has a large bandwidth loss after multiple hops, with an average bandwidth loss of more than 25% per hop, and can reach up to 20 carriages. In the environment of rail transit vehicles, the traditional Mesh networking technology has a total loss of more than 90% under 10 hops, and the final bandwidth cascaded from the front, rear to the center cannot meet the needs of passengers for wireless Internet access.
