1. A method for monitoring network traffic data at a media exposure measurement location, the method comprising:
detecting a wide area network (WAN) data packet transmitted through a WAN, the WAN data packet representing media presented at a client device of a plurality of client devices at the media exposure measurement location, each client device of the plurality of client devices having a respective device identifier;
detecting, within a monitoring interval from the detection of the WAN data packet, one or more local area network (LAN) data packets transmitted through a LAN, each of the one or more LAN data packets specifying a candidate device identifier of a respective one of the plurality of client devices;
generating a score for each candidate device identifier based on a number of the one or more LAN data packets detected within the monitoring interval from the detection of the WAN data packet, wherein the score represents a likelihood that the client device having the candidate device identifier is the client device to which the WAN data packet was transmitted;
based on the scores and based on the one or more LAN data packets having been detected within the monitoring interval from the detection of the WAN data packet, selecting, from the candidate device identifiers, a target device identifier with which to correlate the WAN data packet; and
storing data correlating the selected target device identifier with the WAN data packet representing the media presented at the client device of the plurality of client devices at the media exposure measurement location.
