Abstract: The present disclosure provides a method and a system for managing the identification of devices (DID). A network device may provide the network device information to a server through a network. The server may generate a DID corresponding to the network device, and record the DID and the network device information into a device database. In addition, the network device and the server may share a shared key, which may be used to encrypt the DID and the network device information before the data transmission for enhancing security of the method. Moreover, the server may generate and record an exclusive key (Device Key) for data encryption before the data transmission with the network device, and transmit the Device Key to the network device. Therefore, the Device Key management may be accomplished simultaneously with the DID management to enhance data transmission security between the network device and the server.

Abstract: Time synchronization among nodes in a wireless mobile ad hoc network (MANET) is obtained using a cross layer approach. Each node maintains a routing table that contains entries corresponding to other nodes of the network that are one or more hops away from the node, and topology messages are exchanged periodically among the nodes in order to update their routing tables. A network master node is selected, and remaining nodes that are one or more hops away from the master node are defined as slave nodes. The master node includes master timing information in the topology messages it transmits. The timing information is concatenated to include a first time (T1) at which a topology message was received by the master from each of the slave nodes, and a second time (td) at which the master node transmits a topology message after receiving all the topology messages from the slave nodes.

Abstract: The present invention is to provide a system including at least one storage device for storing at least one file each having a file name, a home gateway having a routing identification code and connected to the storage device, and a server connected to the home gateway via the Internet for receiving the routing identification code and the file name uploaded by the home gateway. The server stores a user's registration information corresponding to the routing identification code. When a terminal device connected to the server via the Internet uses the registration information to pass the server's verification and thus log in the server, the server transmits the file name to the terminal device and, when receiving a request instruction from the terminal device, then retrieves the file from the storage device by way of the home gateway and then sends the file to the terminal device as requested.

Abstract: The present invention is to provide a method for transmitting information between multiple electronic pages. The method is applicable to an information transmission system, which includes at least one terminal device, a web server, a toolbar server and an application server. The terminal device obtains a background page from the web server and a toolbar page from the toolbar server and embeds the toolbar page into the background page. When a user clicks on any of at least one application linking object on the toolbar page through the terminal device, the terminal device is able to obtain a status page from the toolbar server and then store page information on the background or toolbar page into the status page and connect to the application server for obtaining an application page corresponding to the application linking object clicked on, so as to enable the application page to access the page information.

Abstract: Communications in a mobile network are scheduled by defining reservation frames having time slots during which network nodes can transmit certain traffic loads while avoiding interference. The nodes maintain maps that identify the slots as either free or reserved based on each node's existing reservations, and reservation information the node receives from neighboring nodes. A node wishing to transmit traffic determines the number of slots required to carry the traffic, selects a first set of slots from among those identified in its maps as free, and transmits a reservation initiation message (RIM) that identifies the first set of slots. Nodes receiving the RIM determine which, if any, of the first set of slots are already reserved based on their own maps, and transmit counter reservation initiation messages (CRIMs) if any slots are reserved. The CRIMs also identify those slots that the CRIM transmitting nodes determine to be currently free.

Abstract: A method of providing medium access control for a wireless mobile ad hoc network includes defining a TDMA network timing frame including a data (DATA) zone having one or more time slots structured to support multiuser detection (MUD) of concurrent transmissions during each slot, a negative acknowledgment (NACK) zone during which nodes transmit requests for retransmission of packets destined to but not successfully received by the nodes, a broadcast (BC) zone during which network management messages are broadcast to the nodes, and a control (CTRL) zone. A primary master (PM) node is selected and operates as a source of network time for all the nodes. Each node synchronizes its time to that of the PM node during the CTRL zone in a distributed manner, by exchanging control messages with the PM node or other nodes located one or more hops from the PM node.
