Title:
INFORMATION DISTRIBUTION SYSTEM, SENSOR NODE, COMMUNICATION NODE, INFORMATION DISTRIBUTION METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2016189093
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an information distribution system capable of reliably distributing information such as disaster information to users.SOLUTION: An information distribution system includes a plurality of sensor nodes and a plurality of communication nodes. Each sensor node performs sensing with a sensor and communicates with another sensor node. Each communication node communicates with a sensor node, and also communicates with a terminal and another communication node. A sensor node transmits sensing results from a sensor to another sensor node and a communication node adjacent to itself as first information. When it receives the first information, a sensor node transmits the first information to another sensor node and a communication node adjacent to itself. When it receives the first information, a communication node transmits the first information to another communication node adjacent to itself, and distributes second information estimated on the basis of the first information to the terminal.SELECTED DRAWING: Figure 1
