摘要： The present invention relates to a data collection system and a data collection method in a sensor network, enabling sensor modules to consume lower amounts of power. The base station transmits data collection request signals to one or more sensor modules which are lower than the base station by 1 in a tree structure. Each sensor module which has received the data collection request signal transfers the signal to one or more sensor modules which are lower than the module by 1. The base station regards the transfer of the signal as ACK for the data collection request signal transmitted therefrom to the sensor module which is lower than the base station by 1. The transmission of a data collection acknowledgement signal starts from a sensor module at the low-order end. When a sensor module receives the data collection acknowledgement signal from a downstream sensor module which is lower than the module by 1, the module transmits the signal to an upstream sensor module which is higher than the module by 1. The downstream sensor module regards the transmission of the signal as ACK for the data collection acknowledgement signal transmitted therefrom, and enters standby mode. In this manner, the sensor modules enter standby mode in sequence starting from the sensor module at the low-order end. Thereby, it is possible to achieve reductions in the frequency of signal transmission while maintaining reliable data communication. Thus, each module consumes lower amounts of power.

摘要： Disclosed is a telemetering system that comprises a wireless base station and a number of wireless sensor nodes. Each wireless sensor node includes a solar cell, a sensor for producing observation data indicating a quantity being measured, a wireless interface for receiving the observation data from the sensor when the node is activated, and a time-schedule memory for storing time-schedule data. Control circuitry briefly activates its own node by supplying power from the solar cell to the wireless interface at periodic intervals according to the time-schedule data of the memory and briefly establishes a wireless link to the base station. During the time the wireless link is briefly established, the control circuitry of each node transmits the observation data to the base station and updates its time-schedule memory if it receives time-schedule data from the base station.

摘要： A data transmission path establishing method for establishing a data transmission path from each device to a base station independently to thereby form a network with small devices which are required to consume lower amounts of power such as sensors, a radio communication network system and a sensor network system. A base station transmits detection signals to a plurality of radio devices. Each of the radio devices which have received the detection signal transmits detection response signals each including an identifier that uniquely identifies the device and doubling as a response signal and a detection signal for another radio device. Having received the detection response signal from a radio device, the base station recognizes the radio device as a radio device belonging to the station based on the identifier included in the detection response signal. In the case where a downstream radio device receives a detection response signal from an upstream radio device, the downstream radio device belongs to the upstream radio device. Also the downstream radio device transmits a detection response signal to the upstream radio device. When receiving the detection response signal from the downstream radio device, the upstream radio device transmits a link information signal indicating the identifier of the downstream radio device to the base station.

摘要： A packet switch includes (a) a plurality of inputs into each of which a packet is input, (b) a switch which receives the packet from the input and switches an output through which the packet is transmitted, and (c) a scheduler which controls the switch. The scheduler (103) includes (c1) a shuffler (201) which shuffles an order of precedence in a first request transmitted from the input to transfer the packet, (c2) a schedule algorithm (202) which determines the output, based on the first request having the order of precedence having been shuffled by the shuffler, and produces a second request to transfer a packet which second request is associated with the first request having the order of precedence having been shuffled by the shuffler, and (c3) a re-shuffler (203) which turns an order of precedence of the second request to be identical with the order of precedence in the first request as found before having been shuffled by the shuffler, and returns the thus turned order of precedence back to the input.

摘要： In an ATM network, each logical subnetwork comprises a server for resolving an ATM address using layer-3 address of request message and routing a packet to the network by using a layer-3 address of the packet. A source client examines a layer-3 header of a packet to determine whether its mode of transmission is connection-oriented or connectionless, and transmits the packet, if it is connectionless, to the server for causing it to route the packet through the network, and transmits, if the packet is connection-oriented, an ATM address resolution request message to the server. The source client receives a reply message from the server containing a resolved ATM address, and transmits a signaling message containing the resolved ATM address to the network to establish a connection. Over the established connection, the source client transmits data packets.
