Mobile communication system based on wireless Ad hoc network

Abstract

The invention provides a mobile communication system based on a wireless Ad hoc network. The basic thought is that each communication device in the mobile communication system periodically transmits a route data frame including a link state message; a local communication device updates a calculated link state value to the link state message, and broadcasts the link state message conforming to a certain condition, so that a link state between the local communication device and a destination communication device can be represented by the link state value of the link state message transmitted by the local communication device after an adjacent-hop communication device receives the link state message transmitted by the local communication device; and each communication device maintains routing information according to the received route data frame, and determines an optimal next-hop communication device of each communication device in order to ensure an optimal communication path between each communication device and the destination communication device, so that the wireless Ad hoc network which is free from a fixed center, is high in robustness, is not limited by a network center node on the aspect of network communication range, and is high in network communication performance is built.

Description

technical field

[0001] The invention belongs to the technical field of communication, in particular to a mobile communication system based on a wireless ad hoc network. Background technique

[0002] Common mobile communication devices (such as mobile phones) communicate with each other mostly through cellular base stations or wireless local area network (WLAN) access points, and then access cellular base stations or wireless local area networks when these mobile communication devices are relatively close. Access points need to communicate with each other, which will not only lead to an increase in communication costs, but also increase the burden on cellular base stations or wireless LAN access points. In addition, cellular base stations and wireless LAN access points are not always available, and it is not practical for mobile communication devices to communicate with each other via cellular base stations or wireless LAN access points in remote areas without cellular networ...
