The proposed technology generally relates to route determination and routing in a multi-hop network, More specifically, it provides for a method for route determination in a multi-hop network comprising a number of nodes, 11, whereof at least two nodes are target nodes, 12. The method comprises the steps of: including, S1, in the multi-hop network, a fictitious node, the fictitious node, 15, being defined to have fictitious links to at least two of the target nodes, determining,S2, at least part of one or more extended routes for connecting one or more of the nodes comprised in the multi- hop network, to the fictitious node and determining, S3, at least a part of a route in the multi-hop network, using the at least part of one or more extended routes. One aspect of the proposed technology relates to a method and device for route determination in a multi-hop network having several gateways or aggregation nodes for connecting to a communication network, a method and device for routing in a multi-hop network as well as a corresponding device and computer program. The proposed technology also relates to an aggregation node and to a method in an aggregation node. |
