Abstract
Disclosed is a system for providing handover of a mobile node in a wireless network supporting Mobile IP (Internet Protocol). The mobile node sends, when handover is needed, a request for neighbor access router information to a first access router currently communicating with the mobile node, and selects, if the neighbor access router information is received, a second access router serving as a target access router using the received neighbor access router information. The first access router exchanges access router information with a neighbor access router, provides neighbor access router information to the mobile node upon receiving the neighbor access router information request from the mobile node, and redirects data to be delivered to the mobile node to the second access router to which the mobile node will be handed over. The second access router forwards data to be delivered to the mobile node, received from the first access router, to the corresponding mobile node.
