摘要： Methods and systems for discovery of a set of nodes (20, 30) in a network (165). The method comprises selecting (S11) a node (20) amongst nodes in a group of nodes to be processed; and instructing (S12) to implement a discovery procedure for the selected node. The procedure comprises broadcasting (S22) a neighbor discovery request from a node (20) currently selected on a shared transmission medium (1) of the network; and receiving (S23) at the node (20) currently selected replies sent (S34) by neighbor nodes on the shared transmission medium and adding (S13) the neighbor nodes to the group of nodes to be processed; and repeating (S14) the steps of selecting and instructing for other nodes (30) in the group of nodes to be processed, until all nodes of the set are discovered.

摘要： Methods support a sleep mode for an embedded device. Embedded devices like sensors and actuators used in wireless sensor networks have a limited power supply. To conserve energy and thus increase the lifetime of these devices, the devices should be put into a stand-by mode (also called sleep-mode) when they are not used. These methods support the sleep mode at a higher level than the MAC layer, thus avoiding the problems of prior art approaches. Methods are exemplarily described for the case of the message queuing telemetry transport protocol for sensor networks. They can easily be adapted to other protocols.

摘要： The present invention discloses an apparatus and method for adapting a transmission parameter in a transmitting node of a data communication system to the current link quality of a data communication channel. The adapted transmission parameter is selected by the transmitting node from a set of transmission parameters in dependence on a number of successful transmissions. The number of successful transmissions is compared in the transmitting node against one of a first threshold value corresponding to a first state of the transmitting node and a second threshold value corresponding to a second state of the transmitting node. The method comprises in the transmitting node the steps of (a) counting the number of successful transmissions; (b) selecting the adapted transmission parameter (b1) in response to the number of successful transmissions equaling or exceeding the first threshold value when the transmitting node is in the first state, and (b2) in response to the number of successful transmissions equaling or exceeding the second threshold value when the transmitting node is in the second state; and in dependence of the result of a following transmission, operating the transmitting node in one of the first state and the second state.

摘要： A sensor network has a plurality of wireless sensors which transmit to an intermediate receiving device which relays data to a central server. A method is provided for receiving data packets at the intermediate receiving device from a plurality of the transmitting devices. Data packets are sensed on a communication medium at the receiving device and the total traffic intensity of data packets from the transmitting devices is estimated. A detection threshold for data packets is provided and adapted as a function of the total intensity. The receiving device receives data packets with a signal strength above the current detection threshold.

摘要： A telephone session between a calling person and a called person uses a call-related information segment which has been prepared by the calling person to inform the called person of the calling person and the subject of the session. The call-related information is transmitted to the called person and outputted there by use of an output unit, alerting the called person of the nature of the telephone session without the called person entering into the telephone session.
