Cross-network communication method and communication device and system based on wireless ad hoc network

Abstract

The invention relates to a wireless ad hoc network, and belongs to the technical field of communications. A cross-network communication method based on the wireless ad hoc network is characterized by comprises the steps that when data in the wireless ad hoc network applies for transmission, a target terminal of data transmission is judged; when the target terminal does not belong to terminal equipment in the wireless ad hoc network, to-be-transmitted data is adapted to a data packet of a remote communication protocol; the data packet is transmitted to a communication module of the remote communication protocol through a communication serial interface to be converted into remote communication. A cross-network communication device achieving the cross-network communication method comprises a wireless ad hoc network communication module and a remote communication module, the wireless ad hoc network communication module is connected with the remote communication module through the communication serial interface to transmit data, and the wireless ad hoc network communication module comprises a data transmission terminal judgement sub module and a data adaptation sub module in the wireless ad hoc network. The invention further provides a cross-network communication system which achieves multiple mode communications of short distance and long distance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an ad hoc network-based cross-network communication device, communication method and system. Background technique [0002] Mobile ad hoc (Ad Hoc) network is a multi-hop temporary autonomous system. The entire network has no fixed infrastructure and can provide Intercommunication between terminals. Each user terminal in the wireless ad hoc network has both functions of a router and a host. As a host, a terminal can run various user-oriented applications; as a router, a terminal needs to run corresponding routing protocols. This distributed control and non-central network structure can guarantee the necessary communication capability after the wireless communication infrastructure signal is blocked or the signal coverage is weak or part of the communication network is damaged, and it has strong robustness and invulnerability. sex. [0003] The wireless ad hoc net...
