Patent number: 8379621Abstract: In general, an Internet gateway assigns an address to a node of an ad-hoc network on receipt of request for an address assignment. However, a load exerted to the Internet gateway increases. Accordingly, one (proxy node) of the nodes of an ad-hoc network can serve as a proxy node to perform an address assignment function of the Internet gateway. That is, if a node of the ad-hoc node does not receive an advertisement message, it requests the Internet gateway for address assignment to perform the proxy node function. The node is assigned with at least two addresses from the Internet gateway, and then assigns the address to the requesting node. Accordingly, a load exerted to the Internet gateway can be reduced.Type: GrantFiled: September 8, 2005Date of Patent: February 19, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-lim Kang, Jae-hoon Kim, Jung-ho Kim, Yong-sung Roh, Young-gon Choi, Shubhranshu Singh, Kee-cheon Kim, Dong-keun Lee, Hyun-sik Kang

Patent number: 8335511Abstract: An ad-hoc network and routing method that takes account of mobility are provided. The ad-hoc network includes at least one node, which calculates a probability that a neighbor node is present in a transmission range of the node, generates a message containing the calculated probability, and transmits the message to the neighbor node. The at least one node may also update the message with a lower probability of the calculated probability and a probability contained in the message, and transmit the updated message to the neighbor node. The node may also determine as a route a path along which a message is transmitted from the message containing the highest probability among probabilities contained in messages that are received.Type: GrantFiled: January 17, 2006Date of Patent: December 18, 2012Assignees: Samsung Electronics Co., Ltd., George Mason Intellectual Properties, Inc.Inventors: Shubhranshu Singh, Yong-sung Roh, Jae-hoon Kim, Kyung-lim Kang, Young-gon Choi, Jung-ho Kim, Brian L.

Patent number: 7836155Abstract: A method for assigning a global address to a node in an ad-hoc network is provided. A joining node to the ad-hoc network generates a local address using its MAC address. The joining node inquires of its one-hop nodes about whether they occupy a local address that is the same as the generated local address. When the joining node is informed that there are no nodes occupying the same local address, it generates a global address using the generated local address and a global prefix provided from neighbor nodes. The joining node inquires of an Internet gateway about whether the generated global address is currently used. When the joining node is informed that there are no nodes currently using the same global address, the joining node is assigned the generated global address. Further, the joining node and the Internet gateway communicate messages via a relay node using a tunneling.Type: GrantFiled: January 20, 2006Date of Patent: November 16, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-lim Kang, Young-sung Roh, Jae-hoon Kim, Young-gon Choi, Jung-ho Kim, Shubhranshu Singh, Jae-pil You, Dong-keun Lee, Hyun-sik Kang

Patent number: 7787424Abstract: A method for relaying packets through a relay node in a communication system composed of a source node, a destination node and at least one relay node for transferring the packets transmitted from the source node to the destination node. The relay node compares a potential corresponding to a number of hops and constituting the transferred packets with a stored potential from the destination node. If the stored potential is smaller than the potential constituting the packets, the relay node updates the packet and broadcasts the updated packets. Also, according to a method for setting a route for transmitting packets, packets are broadcast and it is checked whether updated packets obtained by updating the broadcast packets are received. If updated packets are received, an address of a packet transmission node constituting the updated packets is stored and the following packets are transmitted to the node having the stored address.Type: GrantFiled: June 30, 2005Date of Patent: August 31, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-lim Kang, Jae-hoon Kim, Jung-ho Kim, Yong-sung Roh, Young-gon Choi, Shubhranshu Singh, Jeong-sik In
