System and method for discovery of neighborhood communicating objects

The invention relates to a system for determining surroundings in a wireless network, the system including first and second nodes, each node being programmed to periodically detect the nodes located in the surroundings thereof every time period Delta, characterized in that: the first node comprises a transmitter (1) and control means (3) for activating the transmitter (1) for a transmission time xi less than the time period Delta, the transmitter transmitting an identification signal during the transmission time xi; the second node comprises a receiver (2) and control means (3) for activating the receiver (2) for a reception time alpha less than the time period Delta, the receiver (2) listening for the signals from the adjacent nodes during the reception time a, the control means (3) of the second node activating the receiver once per time period Delta.
