QoS-aware handover procedure for IP-based mobile ad-hoc network environments
First Claim
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.

Abstract
A handover method for a wireless mobile network including interconnected mobile nodes having time varying connectivity includes determining Quality of Service (QoS) resources of each potential routing path between a mobile node and a correspondent node. The method also includes 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. In addition, the method includes 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.

17. A mobile base station, comprising:
-
a determining unit configured to determine Quality of Service (QoS) resources of each potential routing path to a correspondent node; a pre-allocating unit configured to pre-allocate the QoS resources along at least one potential routing path in advance before initiating a handover of a data flow to be transmitted to the correspondent node via a selected routing path; a redirecting unit configured to redirect the data flow to a routing path with best available QoS capabilities as the selected routing path and, in case of sufficient QoS capabilities, reserve QoS resources for the data flow to be transmitted via the selected routing path.

18. A computer program product that stores computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a 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.
