Abstract:
A wireless ad-hoc network for transmitting packets to target regions, and a packet transmission method thereof, are provided. The ad-hoc network includes at least one relay node for receiving a packet containing location information of at least two target regions each including at least one node, separating the received packet by the location information, forming a new packet for each instance of the location information separated from the received packet, and forwarding the new packets to corresponding target regions; and a source node for generating the packet containing the location information and transmitting the packet to the relay node. The present invention can reduce the packet transmission overhead, the packet transmission delay, and the power required for the packet transmission. Therefore, the packets can be delivered to the target regions in an efficient manner.
Abstract:
An adhesion composition is disclosed. In one embodiment, the composition includes a gel material and an adhesion resin, a weight ratio of the gel material and the adhesion resin ranging from about 1:10 to about 1:100.
Abstract:
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.
Abstract:
A method, medium, and system for connecting to a communication system in a network having a plurality of nodes capable of communicating with each other. The node requests an identifier to a foreign network when a router advertise (RA) message is received from the foreign network, and then the node connects to the communication system, via the foreign network, by use of the received identifier. A method, medium, and system for delegating a network identifier (prefix) from a server of a foreign network, in a network having a plurality of nodes capable of communicating with each other, so that a node can communicate with the foreign network. The prefix to be used by the nodes in the network is transmitted from the server of the foreign network to the node.
Abstract:
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.
