Pathfinding network topology structure for emergency communication and routing method thereof

Abstract

The invention discloses a pathfinding network topology structure for emergency communication and a routing method thereof,in order to solve the problem that in the prior art, an emergency communication pathfinding network topology structure is complex. According to the implementation scheme, a pathfinding network is divided into a vehicle-mounted network layer and an individual soldier network layer, one layer is formed by vehicle-mounted nodes with relatively stable structures, the other layer is formed by individual soldier backpack or handheld nodes with dynamically changing structures, andthe individual soldier nodes have a relay routing function. The vehicle-mounted network is used as a target network of the route, and the individual soldier network is used as a source network and arelay network of the route. According to the routing method based on the pathfinding network topological structure, for a two-hop network, transmission time delay caused by different channel conditions of feasible paths and processing time delay caused by processing of data packets by relay nodes are comprehensively considered, and an optimal path is selected to transmit the data packets under thecondition that the energy of individual soldier nodes is limited. The pathfinding network topology structure is simple in structure and small in end-to-end time delay, and can be used for emergency communication of major sudden disasters in cross-border geological complex areas.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a road exploration network topology structure and a routing method thereof, which can be used for emergency communication of major sudden disasters in cross-border geological complex areas. Background technique [0002] In order to meet the emergency communication needs of major sudden disasters in cross-border geological complex areas, the research on emergency communication systems is an urgently needed technology. [0003] my country is a country prone to natural disasters. Natural disasters such as earthquakes, floods, and transit typhoons occur from time to time. Especially in recent years, major disasters such as earthquakes, floods, mudslides, and fires have occurred frequently. When encountering these emergencies, when the communication facilities are destroyed, the communication is forced to be interrupted, and it is difficult to recover in a short time...
