Method, system and computer program for retrieving information with reduced age in a periodic process

摘要

A solution ( 600 ) for retrieving information (for example, monitoring data such as heartbeat signals) is proposed. The information is collected ( 603 - 612 ) periodically on a central server ( 110 ) from remote sources ( 105 ); multiple clients ( 120 ) then download ( 615 - 630 ) the information from the server with a time pattern that is tied to the period of the collection. In the proposed solution, each client at every iteration estimates ( 633 ) the time at which the different information items will be received on the server from the corresponding sources at the next iteration (for example, considering a delay for their collection equal to the one of the last iteration). The client then determines ( 636 - 651 ) the time of the next request to be submitted to the server so as to minimize the corresponding total age of the information items.
