Wireless self-organized network-based integrated heterogeneous emergency communication network

Abstract

The invention discloses a wireless self-organized network-based integrated heterogeneous emergency communication network. The emergency communication network comprises a layered framework, a layered framework-based system structure and a layered framework-based network structure, wherein the layered framework consists of a communication network layer, an information acquisition layer, a distributed computation layer and an application service layer sequentially from bottom to top; the system structure consists of a network infrastructure layer, a public service layer, a specific functional layer and an application system layer sequentially from bottom to top; and the network structure is a layered three-dimensional communication network structure. The emergency communication network provided by the invention can adapt to various emergency network deployment situations, can provide network capacity and a coverage area at any given time or place as required, can be conveniently expandedto a network of a required scale, enhances situational perception capability of an emergency occasion by comprehensively utilizing various communication measures, shortens transmission time delay andcall establishment time, can support the requirement on the performance of various services and expands the communication ranges and service support capabilities of various user groups on different emergency occasions.

Description

technical field [0001] The invention relates to a network system structure, in particular to an integrated heterogeneous emergency communication network based on a wireless ad hoc network. Background technique [0002] A large number of facts show that in the face of sudden emergencies, the existing communication network is often unable to meet the special communication needs of emergency situations. How to quickly establish a reliable, efficient and robust emergency communication network suitable for various user groups has become an urgent task in the industry. major issues to be addressed. Compared with western developed countries, my country's emergency communication technology is relatively backward. At present, domestic emergency communication mainly relies on existing communication facilities (including public communication network and public media network), and when the infrastructure is damaged or cannot meet the communication needs, satellite, short-wave and dedic...

AI Technical Summary

Problems solved by technology

However, most of these research works are not for the purpose of emergency communication guarantee. They pay little attention to the internal connection and organic integration between various wireless ad hoc networks and between wireless ad hoc networks and existing basic network facilities, and lack of specific Systematic research on establishing and maintaining heterogeneous emergency communication network based on actual application requirements of emergency communication

In addition, most of the current research work does not fully consider the differences in communication needs and special communication modes of various user groups in emergency scenarios, and the proposed emergency communication network solutions generally lack adaptability and scalability
