摘要： Embodiments of the present invention provide a method for tracking link mobility between two mobile nodes. Each node estimates a link mobility state of a link between itself and each of its neighbor nodes, accumulates successively the link mobility states, estimates link mobility parameters using the successively estimated link mobility states, and predicts a link availability probability using the link mobility parameters. The link mobility tracking can be applied to various routing protocols so as to implement mobility aware routing which enhance the routing performance.

摘要： An ad-hoc network for routing extension by supporting the IPv6 protocol and a method for routing extension. The ad-hoc network comprises a gateway for appending an address configuration message to an ad-hoc Routing REPly (RREP) message and transmitting an extended ad-hoc RREP message; and a node for separating the address configuration message from the received extended ad-hoc RREP message, establishing a packet transmission path using the ad-hoc RREP message, and configuring a global address using the separated address configuration message. Accordingly, the present invention provides efficiency and improves the network scalability by utilizing the existing IPv6 protocol without amendments and reducing the size of the packet transmitted.

摘要： 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.

摘要： 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.

摘要： Disclosed is a method for a hybrid service discovery adapting between push-based and pull-based schemes in a mobile ad-hoc network and a system thereof. The method includes periodically transmitting a first control packet for providing service information from a service provider that is capable of providing a service to nodes located in a specified advertisement zone, transmitting a second control packet requesting the service from a service demander to one or more nodes in a network, and transmitting a third control packet including path information of the service provider if at least one of the nodes located within the advertisement zone and the service provider receives the second control packet. The method and the system can reduce the amount of control packet transmission and minimize an end-to-end delay.
