The invention relates to a method for associating time slots (S0, S1,..., S16) with links (L1, L2, L16) between network nodes (1, 2,..., 10) of a wireless interconnected network, wherein the data in the network can be transmitted from a source node to a destination node on a time slot basis by means of said association via hops or corresponding hop levels (H-2, H-1,..., h+2). In the method according to the invention, a main path (MP) having one network node (1, 2, 3, 4) per hop level (h-2, h-1,..., h+2) and the corresponding links (L1, L2, L3, L4) between the network nodes (1, 2, 3, 4, 5) of adjacent hop levels (h-2, h-1,..., h+2) is set from the source node to the destination node. Alternative network nodes (6, 7, 8, 9, 10) having corresponding alternative links (L5, L6,..., L14) are also set, which can be used in place of the main path (MP) for data transmission. A suitable association of time slots with links of the main path, and alternative links, an energy-efficient time slot based data transfer is made possible. The method can be used, for example, in sensor networks, which generally comprise sensors having autonomous energy supply. The method according to the invention can further be used in the course of a data transfer, based on the per se known standard WirelessHART. |
