Neighbor discovery method and apparatus for mobile node in heterogeneous network environment

摘要

A neighbor discovery method and apparatus for performing network-transparent neighbor discovery in a heterogeneous network environment is provided. A neighbor discovery method for a multi-mode mobile node includes determining a type of a network, with which a mobile node is in communication, in response to a detection of a request for sending a neighbor solicitation message, retrieving, if the network type identifies a self-processing network, information about the network from a database, determining whether a tentative address contained in the neighbor solicitation message is already in use by another node with reference to the information about the network, and generating, when the tentative address is already in use, a neighbor advertisement message.
