Abstract
Disclosed herein is a method of allocating an Internet Protocol (IP) address and detecting the duplication of the IP address in an ad-hoc network environment. In the method of the present invention, a terminal allocates an IP address to itself and efficiently detects and handles the duplication of the IP address in the ad-hoc network environment, thus reducing the load of an entire network and allowing the method to be used together with existing routing protocols.
Claims11
A method of allocating an Internet Protocol (IP) address and detecting duplication of the IP address in a network environment, comprising the steps of:
- allocating an initial IP address to a terminal;
- sending and receiving broadcast messages;
- detecting duplication of the IP address while sending and receiving the broadcast messages;
- updating a Duplicate Address Detection (DAD) table through searches of at least one of a DAD table and a history table;
- and
- determining whether a collision of the IP address occurs using a DAD timer handler.
A method of allocating an Internet Protocol (IP) address and detecting duplication of the IP address in a network environment, comprising the steps:
- (a) initially allocating a tentative IP address to a terminal;
- (b) determining whether the tentative IP address can be used by the terminal;
- (c) comparing the tentative IP address with at least one other IP address;
- (d) if the tentative IP address has a duplicate, selecting an advisory IP address that does not exist;
- (e) sending the advisory IP address to the terminal;
- (f) performing step (b) using the advisory IP address as the tentative IP address.
