Abstract:
1. A method for performing a handover in a mesh network for a plurality of nodes of the mesh network from a first access point to a second access point, whereas the plurality of nodes forms a tree of nodes, the tree comprising a root node and one or more further nodes connected to the root node either directly or via intermediate nodes, and the handover being performed for the tree of nodes in a coordinated fashion, the method comprising: determining the root of the tree and the second access point; forwarding to the nodes of the tree information about the second access point and timing information to enable a coordinated handover of the nodes of the tree; switching the root node and the further nodes to disconnect from the first access point and subsequently to connect to the second access point according to the timing information; and sequentially switching the nodes of the tree starting with the root node followed incrementally by the further nodes according to their sequence into downstream direction.
