ABSTRACT:
A method and system for dynamically updating information registered in ARP cache tables of other terminals in a case where a protocol address of a terminal existing in an ad hoc network changes. The method includes detecting whether protocol addresses of terminals are duplicated and changing the protocol addresses of some of the terminals having the duplicate protocol addresses; by a terminal whose protocol address has changed, transmitting information on the previously used protocol address and its own hardware address to neighboring terminals; updating the address information tables in accordance with the received information; by a terminal whose protocol address has not changed among the terminals having the duplicate protocol addresses, transmitting its own address information to the neighboring terminals; and by the neighboring terminals that has received the address information in the fourth step, updating the address information tables in accordance with the received information.
