Dynamic ad hoc network wireless communication device

Abstract

The invention provides a dynamic ad hoc network wireless communication device. The dynamic ad hoc network wireless communication device comprises a central processing module, a data processing module, a SDRAM (Synchronous Dynamic Random Access Memory) storage module, an integrated service interface management module, a modulation module, a demodulation module and a frequency conversion module, wherein the data processing module performs background encapsulation and data conversion on IP (Internet Protocol) data which need to be emitted based on an FPGA (Field Programmable Gate Array), and comprises a modulation mode signaling of a signal; and the central processing module manages an instruction of calling a program in the data processing module and performs lumped processing, issuing and control on the data based on a design of a central processing chip. The dynamic ad hoc network wireless communication device provided by the invention is based on an Ethernet IP communication design, and the same frequency is adopted to the data receiving and sending; besides, the dynamic ad hoc network wireless communication device has the advantages of being small in size, low in power consumption, convenient to use and flexible in networking.

Description

technical field [0001] The invention relates to the field of radio communication, in particular to a dynamic ad hoc network wireless communication module. Background technique [0002] Ad hoc network (Mesh network), namely "wireless mesh network", is a dynamic network architecture that can be continuously expanded. Any two devices can maintain wireless interconnection. In this Mesh network structure, each network node passes through Adjacent to other network nodes, they are connected in a wireless multi-hop manner, which has the characteristics of no need to set up network facilities, rapid deployment, and strong invulnerability. It is one of the key technologies to solve the "last mile" problem. During the evolution to the next generation network, the wireless mesh network is an indispensable technology. Wireless mesh can communicate cooperatively with other networks. [0003] The existing multi-module, multi-channel, multi-radio technology S-band and C-band wireless Mesh...

AI Technical Summary

Problems solved by technology

[0003] The existing multi-module, multi-channel, multi-radio technology S-band and C-band wireless Mesh products have inconsistent access and return frequencies, and the workload of detecting channels of different frequencies is relatively large. When the number of nodes in the Mesh ad hoc network If it takes a long time to detect, it will cause data delay and reduce the quality of network transmission.

In addition, the core processing system of the existing Mesh products has single and fixed functions. With the expansion of the Mesh network architecture, the calculation load of the core processing system has greatly increased. The original functional modules can no longer fully adapt to different needs. The upgrade cost of the processing system is very high, which hinders the development of the Mesh network
