摘要： Routing schemes are provided for a communication network. In one scheme, destination terminals and associated neighboring terminals are listed in a routing control cache at each communication terminal in the network, and packets are routed toward the destination terminal through the associated neighboring terminals. In another scheme, a single path from a source terminal to a destination terminal is automatically expanded into multiple paths. In yet another scheme, packets are routed as long as this does not increase the number of hops to the destination terminal. These schemes enable multiple paths to be established by a simple procedure not requiring complex distance calculations. In still another scheme, routing is restricted to the shortest path and paths up to a given number of hops longer than the shortest path, permitting paths to diverge in multiple directions from the source and destination terminals.

摘要： Each node or terminal in a communication network is capable of generating routing information for routing packets from an arbitrary source terminal to an arbitrary destination terminal on both a single-path route and a multipath route. The routing information is placed in packets transmitted to neighboring communication terminals, and analyzed in packets received from neighboring terminals. The single-path route is spatially or temporally separated from the multipath route so that the single-path route does not receive interference from the multipath route. Temporal separation may be effected by suspending the transmission of packets temporarily at each communication terminal on the multipath route. Spatial separation may be effected by using the routing information to designate different zones in the network, the single-path route being disposed in one zone, the multipath route in another zone.

摘要： A network path setting method sets a path of a session specified in a wireless mesh network including wireless stations, two of the wireless stations being defined as one end and the other end of the session. First, one or more potential paths are obtained for the session based on the number of hops. When a plurality of potential paths are obtained, wireless resource consumption is calculated for each potential path, or a traffic margin of each potential path is calculated according to the traffic margin of a relaying wireless station. The calculated wireless resource consumption or traffic margin of the potential paths is used as an evaluation parameter to select and set the path of the session. Among a number of connection paths, a connection path is selected which is suitable for the entire network.

摘要： A switch circuit connects a switch (SW) to a connector when a connector receives a signal and connects the switch (SW) to a terminal when the connector receives power. The connector receives a signal and power transmitted at the same frequency, outputs the received signal to a communication unit through an attenuator, and outputs the received power to a power receiving unit. The communication unit carries out reception processing to the signal and outputs the processed signal to a computer. The power receiving unit carries out reception processing to the power and stores the processed power. The power receiving unit supplies the communication unit or the computer with the stored power.

摘要： A source terminal measures characteristics of the path at the source terminal itself, produces a characteristics-measurement packet, and transmits the produced characteristics-measurement packet to a relay terminal. Upon receiving the characteristics-measurement packet, the relay terminal measures characteristics of the path at the relay terminal itself, renews the characteristics of the path included in the characteristics-measurement packet using the measured characteristics of the path, and transmits the characteristics of the wireless communication path to the destination terminal. The source terminal produces an admission-request packet and transmits the packet to the destination terminal. Upon receiving the admission-request packet, the destination terminal allows or rejects the traffic quality maintenance request according to the characteristics of the wireless communication path. The allowance or rejection of the quality maintenance request is transmitted to the source terminal with the admission-reply packet by the destination terminal.

摘要： A multi-hop wireless communication system operates on multiple channels. Each wireless station in the system has at least two transmitting and receiving modules operating on different fixed channels. During transmission and reception of the packets, the transmitting and receiving modules are used selectively on each hop, using a channel supported by the wireless stations at both ends of the hop. When two or more channels are available, the channel used is selected so as to balance channel usage in the system as a whole, or on the multi-hop path as a whole. Alternatively, each wireless station may have a fixed transmitting channel. Communication delays are reduced because channel switching overhead is eliminated.
