Techniques for the distribution and use of application code and detection Filters in wireless devices from device to device (D2D, for its acronym in English). A representative method of ads for a device includes receiving, from a coordinating Node, a First and a Second Application code and associated timing information.The Associated Timer Information defines a First and second validity interval corresponding to the first and second Code implementation, so that the first and second validity interval are, at least in part, without overlaps.The Method further includes transmitting during the first interval of validity Detection, one or more messages that include or are based on the first implementation Code, and during the second pass, validity interval, one or more messages that include detection Or are based on the second Application Code.Also, techniques for monitoring devices.
