1. A mesh node association method by a mesh node in a mesh network, the mesh network comprising a plurality of mesh nodes, the method comprising:
- associating a new mesh node to a particular mesh node among the plurality of mesh nodes;
authenticating the new mesh node by performing, by the particular mesh node, an authentication procedure for the new mesh node;
generating context information comprising authentication information of the new mesh node; and
delivering the context information to at least one neighbor mesh node included in a neighbor list;
wherein the delivering of the context information is performed after the generating of the context information and before the new mesh node requests re-association with any of the at least one neighbor mesh node;
the neighbor list is a neighbor list of the particular mesh node; and
the authentication information of the new mesh node is generated during the authenticating of the new mesh node in the authentication procedure performed by the particular mesh node, and enables the at least one neighbor mesh node to authenticate the new mesh node without performing the authentication procedure performed by the particular mesh node in authenticating the new mesh node.

Abstract
A mesh network has a plurality of mesh nodes, including a moving mesh node. A serving mesh node initially associates with the moving mesh node at the request of the moving mesh node, transmits context information due to the initial association to at least one neighbor mesh node, and transmits information on the at least one neighbor mesh node to the moving mesh node. The at least one neighbor mesh node stores the context information received from the serving mesh node, and re-associates with the moving mesh node using the context information at the request of the moving mesh node.
