Abstract
A method provides for wireless transmission and reception of messages in an asynchronous ad hoc network having multiple network nodes, of which at least a first network node periodically transmits messages with a predefined period length. A second network node carries out: Defining two consecutive time intervals, each having the length of one period and a first time interval being past and a second time interval being future; subdividing the time intervals into two time slots each; calculating an occupancy for each time slot of the first time interval based on the number of messages of other network node(s) received in this time slot; identifying the time slot having the lowest occupancy; and transmitting a message in a time slot of the second time interval that corresponds to the identified time slot. The exact transmission point is defined on the basis of the time stamp derived from the synchronized TSF.
