Abstract: A mobile ad hoc network (MANET) and a method for establishing a routing thereof are provided. The MANET includes a plurality of nodes. Each node determines a corresponding parent node according to a request packet resource of a request packet and a node resource of each node, so as to establish transmission routes between the nodes. Furthermore, needless transmission route is eliminated by the node belonging to a multicast group according to a group table of each node.

Abstract: A data transmission method suitable for a communication system is provided. The communication system includes a plurality of first stations which uses an 802.11 protocol and a plurality of second stations which uses an 802.11e protocol and supports Quality of Service (QoS). The data transmission method includes following steps. One of the second stations is used as a Contention AssisTance (CAT) station to obtain a medium access right with a first access category (AC). The second station broadcasts a CAT packet to all the first stations and the other second stations. The other second stations stop contending for the medium access right for a first predetermined time according to the CAT packet, and the first stations transmit a packet with a QoS requirement according to the CAT packet.

Abstract: A host apparatus, a transmission method and a tangible machine-readable medium storing a program of the transmission method for use in the host apparatus are provided. The host apparatus is for use in a wireless network which comprises a plurality of access points and a mobile node. The access points are wirelessly connected to the host apparatus. The host apparatus stores a statistics table relating to the mobile node. The host apparatus may be aware of the possible moving paths about the mobile node and proceed the data transmission with the mobile node via the access points in the possible moving paths, so as to save the resource of the wireless network.

Abstract: A packet transmission method for WLAN, a controlling method for data transmitting node of WLAN and a controlling method for data receiving node of WLAN are provided. In the packet transmission method, the data transmitting node sends a transmitting request signal. When the receiving node receives the transmitting request signal and cannot immediately perform a transmitting operation defined by the transmitting request signal, a stop-transmitting signal is sent to the transmitting node. After sending the stop-transmitting signal, the receiving node outputs a start-to-transmit signal to the transmitting node when the transmitting operation can be performed. The transmitting node sends the data after receiving the start-to-transmit signal.

Abstract: A system for providing voice communications between an end terminal in a packet data network and a wireless communication device includes a packet communication supporting subsystem, a base station subsystem, and a Voice-over-Internet-Protocol Mobile Switching Center (“VMSC”). The packet communication supporting subsystem communicates with the packet data network and also operates to locate the wireless communication device. The base station subsystem communicates with the wireless communication device, and also communicates the packet data network through the packet communication supporting subsystem in the form of data packets. The VMSC communicates with the packet communication supporting subsystem through a packet-switched network and communicating with the base station subsystem through a circuit-switched network.

Abstract: A multicast management mechanism for mobile networks. The mechanism proposes a multicast table approach to considerably reduce the number of short messages and multimedia messages sent to a service area, thereby reducing its paging cost. The multicast management mechanism for mobile networks includes the steps: establishing a VLR recorder table in a home location register (HLR), to record VLR addresses located by multicast users and the total number of multicast users in each VLR; and establishing LA tables, to record LA addresses in each VLR and the total number of multicast users in each LA.
