Abstract: 본 발명은 다중-링크 서브넷 모델로 인한 문제를 해결한 수정된 MANET 구조에 따른 connected MANET에서 MANET 내의 소스 호스트가 MANET 내의 다른 호스트나 외부 인터넷 망의 호스트와 IP 패킷을 주고받을 수 있도록 해주는 경로 결정 방법을 제공한다.
이를 위해 소스 호스트와 목적지 호스트의 IP 주소를 MANET 프리픽스로 서브넷 마스킹해서 목적지 호스트가 소스 호스트와 동일 MANET에 존재하는지 또는 외부 인터넷 망에 존재하는지를 결정한다. 만일 목적지 호스트가 동일 MANET에 존재하면, 소스 호스트가 연결된 MANET 라우터가 RREQ 메시지를 보내고 목적지 호스트가 연결된 MANET 라우터가 이 RREQ 메시지를 수신하면 RREP 메시지를 보냄으로써 소스 호스트와 MANET 내 목적지 호스트 간 경로 결정을 할 수 있게 한다. 만일 목적지 호스트가 외부 인터넷 망에 존재하면, 소스 호스트가 연결된 MANET 라우터가 IP 패킷을 캡슐화해서 MBR에게 보내면 MBR이 캡슐화된 IP 패킷을 역캡슐화해서 외부 인터넷 망에 있는 목적지 호스트에게 전달한다.

Abstract: PURPOSE: A route determination method for the modified MANET architecture that overcomes the problems of a multi-link subnet model is provided to enable a host within a MANET to exchange an IP packet with an external Internet network or another host within the MANET. CONSTITUTION: A MANET(Mobile Ad-hoc Network) router determines whether or not a source host and a destination host belong to the same MANET. In addition, the MANET determines whether or not the source host and the destination host are placed in the external Internet, and finds out the path to the destination host. The MANET router connected to the host transfers the path information to the source host.

Abstract: An area-based overlay multicast method using geographical information in a mobile ad hoc network is provided to be capable of dividing network topology into areas by using geographical information of group member nodes, while limiting a location updating range to related areas only, thereby reducing packet overheads related to location information maintenance. Topology of a mobile ad hoc network is divided into areas(106). Non-group member nodes(104) demand multicast session subscription to a GC(Group Coordinator)(100) to become group member nodes. Group member nodes(102) demand multicast session secession to the GC(100) to become non-group member nodes. The group member nodes(102) periodically notify another group member nodes within a self area of location information on the group member nodes(102). When the group member nodes(102) move between the areas(106), the group member nodes(102) notify the GC(100) and another group member nodes within a new area and a previous area of location information on the group member nodes(102). The GC(100) receiving data packets from a data packet transmitter distributes the data packets to the group member nodes(102) within the mobile ad hoc network.

Abstract: PURPOSE: A method for requesting MANET prefix in a mobile ad-hoc network system employing multi-link subnet model is provided to set up an IP(Internet Protocol) address in a multiple link sub model conveniently. CONSTITUTION: A DHCP(Dynamic Host Configuration Protocol) server receives a DHCP request message(B310), and a DHCP response message including a MANET prefix option to allocate a MANET prefix. A MANET router receives the DHCP response message(B320), and generates an IP(Internet Protocol) address for a host of the MANET router. The host is directly connected to the MANET router(B330). A DHCP(Dynamic Host Configuration Protocol) server receives the DHCP request message(B340).

Abstract: A method for setting a route by using MAC with multiple rates in an MANET is provided to transmit packets based on a higher-speed route and prevent effectively the deterioration of capability caused by additional control information for setting the high-speed route. A method for setting a reactive route by using MAC with multiple rates in an MANET(Mobile Ad-hoc Network) comprises the following steps of: enabling a source MN(Mobile Node)(10) to broadcast a route request message for setting a route to a destination MN(50)(S210,S211); enabling a plurality of MNs, which are disposed in the middle and receive the broadcasted route request message, to process a received message and broadcast the processed message again(S214,S215); enabling the destination MN to process the route request message broadcasted through the plural MNs(S218); and enabling the destination node to transmit the route response message to the source MN with a unicast method(S220).
