Abstract
A method for performing wireless communication in a data-collection system includes a) listening whether a channel is free or busy and if the channel is free, transmitting; b) if the channel is busy, generating a random number and associating therewith a first interval of time to determine the instant of the start of transmission and further whether said channel is busy, identifying a second variable interval of time, monitoring the data exchanged in said channel with other devices that occupy the channel, queuing a third interval of time obtained from said first interval of time onto said second interval of time and transmitting at the end of said third interval of time. The second interval of time has a duration that is equal to the time wherein the channel remains in busy status.
