1. A handover method for a wireless mobile ad-hoc network including interconnected mobile nodes, wherein a connectivity of the nodes is time-varying, the method comprising:

  • determining Quality of Service (QoS) resources of each potential routing path between a mobile node and a correspondent node;

    pre-allocating the QoS resources along at least one potential routing path in advance before initiating a handover of a data flow to be transmitted from the mobile node to the correspondent node via a selected routing path; and

    redirecting the data flow to a routing path with best available QoS capabilities as the selected routing path and, in case of sufficient QoS capabilities, reserving the determined QoS resources for the data flow to be transmitted via the selected routing path.
