Dynamic address allocation method for mobile ad hoc network

A dynamic address allocation method for an ad hoc network, the dynamic address allocation method comprising:

• allowing a new terminal that desires to participate in the ad hoc network to broadcast an address block request message to neighbor terminals in order to be allocated with an address;
• when the new terminal receives no address block reply message from the neighbor terminals, allowing the new terminal to broadcast an address allocation request message to the neighbor terminals;
• when an available address exists in an address block that is used by a 1-hop neighbor terminal in a depleted state, allowing the 1-hop neighbor terminal to transmit an address allocation reply message including the available address to the new terminal;
• allowing the new terminal to transmit an address allocation confirmation message, which informs that the new terminal will use the corresponding address, to the 1-hop neighbor terminal;
• and
• allowing the new terminal to change its terminal state from an alone state to a depleted state.

• allowing a new terminal that desires to participate in the ad hoc network to broadcast an address block request message to neighbor terminals in order to be allocated with an address;
• when the new terminal receives no address block reply message from the neighbor terminals, allowing the new terminal to broadcast an address allocation request message to request for one address to the neighbor terminals;
• when the neighbor terminals are in a depleted state and have no available address, allowing a 1-hop neighbor terminal in a depleted state to broadcast an address allocation request message to the other neighbor terminals in a normal state to secure an address block, and to change its terminal state to a normal state;
• allowing the 1-hop neighbor terminal in a normal state to transmit an address block reply message to the new terminal;
• allowing the new terminal to transmit an address block confirmation message to the 1-hop neighbor terminal;
• allowing the 1-hop neighbor terminal to transmit an address block completion message including an available address block to the new terminal;
• and
• allowing the new terminal to be allocated with an address block and to change its terminal state from an alone state to a normal state.
