The invention relates to a method of data transmission by an ad-hoc network of mobile communication equipment (), from at least one source equipment () to at least one collection terminal (), by means of mobile relay equipment (), in which for each communication equipment, at least one quality factor is updated (Q, QQQQQ). According to the invention, the quality factor of each relay equipment depends on a history of data transmission, and data transmission from mobile equipment to mobile relay equipment is conditional on the quality factor of the relay equipment capable of receiving the data.

Method and equipment for data transmission by ad-hoc network

The invention is intended to be used in the technological field of communication and the update of data between electronic equipment () capable of inter-communicating using wireless links. The invention relates more particularly to a process and a system to automatically configure and update the data saved in a radio frequency identifier (). The process and the system enable the update of the data recorded in a radio frequency identifier of a first equipment item () equipped with a display screen () by displaying on screen a visual code () bearing update data of the radio frequency identifier. The visual code is then read using a second equipment item () provided with a visual code read device () having radio frequency identifier read-write interface. Then, the decoding of the visual code and the conversion and transmission of the update data to the radio frequency identifier by means of the read-write interface are performed.

Process and system for automatically updating data recorded in a radio frequency identifier

The invention is intended for the technological field of data communication between electronic equipment (-) forming part of a system of electronic equipment (). The invention more specifically relates to a method and a system to facilitate, using an identifier having the form of a visual code, the transmission of command data to one of the electronic equipment items of the system, when the electronic equipment that produces the visual code is activated. The transmission of command data intended for one of the equipment items is performed following the reading and decoding of the visual code, for example with another equipment item of the system.
