wherein like reference numerals refer to like elements throughout fig1 shows an exemplary section of a network having a first to fifth network node k 1 5 fig1 also shows a first link l 1 between the first network node k 1 and the second network node k 2 a second link l 2 between the second network node k 2 and the third network node k 3 and a third link l 3 between the third network node k 3 and the fourth network node k 4 the three links l 1 3 form a path from the first network node k 1 to the fourth network node k 4 the links l 1 3 shown as arrows indicate the respective transmission direction used for the path the transmission directions are from the first network node k 1 to the second network node k 2 for the first link l 1 from the second network node k 2 to the third network node k 3 for the second link l 2 and from the third network node k 3 to the fourth network node k 4 for the third link l 3 in the exemplary embodiment of the invention the routing protocol aodv ad hoc on demand distance vector is used as a basis with aodv the network nodes k 1 5 send so called hello messages at regular intervals in this instance 1 second also aodv uses rreq messages rreq route request packet and rrep messages rrep route reply packet when determining a candidate path on the one hand the hello messages serve to determine adjacencies between the network nodes k 1 5 the network nodes k 1 5 of the network also determine data packet.
