The proposed technology generally relates to sending a data packet from a first node 10a to a second node 20, wherein there is a direct link 101 to the second node from the first node. The method comprises the steps of: determining S1 a first power metric, P1, associated with transmitting the data packet from the first node to the second node on the direct link; when the determined first power metric, P1, is above a first power level, L1, then determining S2 a first set of aggregation nodes 10, being within reach of the first node 10a, wherein each aggregation node in the set is comprised in a respective alternative transmission path from the first node 10a to the second node 20; for each aggregation node 10 in the first set determining S3 a second power metric, P2, associated with transmitting the data packet to from the first node to the second node via the aggregation node 10; selecting S4 a transmission path for sending the data packet from the first node to the second node based on a comparison of the first power metric, P1, and the second power metric(s), P2, and sending S5 the packet on the selected transmission path. One aspect of the proposed technology relates to a method and ending a data packet from the first node 10a to a second node 20as well as a corresponding device and computer program. |
