A method of determining the proximity of a first device to a second device, the method comprising, at the second device: receiving a first packet having a first payload and a first lifetime value, the first lifetime value being such so as to cause a device receiving the first packet to not retransmit the first payload; and generating, in dependence on the first packet, a second packet having a second payload and a second lifetime value, the second payload being indicative of the proximity of the first device to the second device and the second lifetime value being such as to cause a device receiving the second packet to retransmit the second payload.
