Method of assigning a network address to each of the wireless devices (SDB i,j) of a network in an aircraft, said devices being able to exchange messages with a network server via at least one access point, each device being placed in the position of a seat in a column of seats (Col j) and powered by a power supply column (PW i) specific to the associated column, characterized in that said method comprises a process (PISDB) of identification, by the server of the column of seats (Col j), of each of said wireless devices based on a message sent by each device after being powered-up, said process of identification by the server comprising the parallel execution of the following steps: ▪ a first step of powering-up the wireless devices (SDB i,j), sequentially by column (col i), with a time delay of known duration (Δ) between the powering-up in one column (col i) and the powering-up in a next column (col i+1), the powering-up of each device triggering a mechanism for sending a message to the server after zero-setting an internal clock of the device, said message containing a time information (b i,j) specific to the device, which is the current value of said internal clock at the moment of sending the message, and ▪ a second step of timestamping, by an internal server clock (DTs) providing a date of reception (t i,j) of said message sent by each powered-up device, and the identification by the server of the column of the device having sent the message, based on the time information b i,j contained in the message, the timestamping t i,j of the message by the server and the delay time Δ for powering-up between the columns, said identification corresponding to the rank i of the column in the powering-up sequence of the columns and being determined by calculation using the following equation: i = (t i,j - t 1 - b i,j - s 0) / (Δ + 1), where s 0 is the average duration of the duration of the boot process of a device between the moment of activation of the boot process and the initialization of the device's internal clock and t 1 the time of powering-up of the first column of the powering-up sequence of the columns. ▪ a first step of powering-up the wireless devices (SDB i,j), sequentially by column (col i), with a time delay of known duration (Δ) between the powering-up in one column (col i) and the powering-up in a next column (col i+1), the powering-up of each device triggering a mechanism for sending a message to the server after zero-setting an internal clock of the device, said message containing a time information (b i,j) specific to the device, which is the current value of said internal clock at the moment of sending the message, and ▪ a second step of timestamping, by an internal server clock (DTs) providing a date of reception (t i,j) of said message sent by each powered-up device, and the identification by the server of the column of the device having sent the message, based on the time information b i,j contained in the message, the timestamping t i,j of the message by the server and the delay time Δ for powering-up between the columns, said identification corresponding to the rank i of the column in the powering-up sequence of the columns and being determined by calculation using the following equation: i = (t i,j - t 1 - b i,j - s 0) / (Δ + 1), where s 0 is the average duration of the duration of the boot process of a device between the moment of activation of the boot process and the initialization of the device's internal clock and t 1 the time of powering-up of the first column of the powering-up sequence of the columns.
