Abstract:
It is disclosed a method for providing a telecare service to a patient. According to the method, at least one sensor installed in a domestic environment of the patient detects a datum relating to either the domestic environment or an interaction between patient and domestic environment. Based on the detected datum, an anomaly in the domestic environment or in the interaction between patient and domestic environment is detected. Then, a predefined question uniquely associated with the detected anomaly is selected for generating a questionnaire to be submitted to the patient, with the purpose of determining the cause of the detected anomaly. According to preferred embodiments, based on the patient's reply it is determined if the detected anomaly is a false anomaly and, in the affirmative, the predefined question associated to such false anomaly is excluded from the next questionnaire(s), even if the anomaly persists.
Abstract:
A method, implemented by a data processing system (125), of adjusting modifiable parameters of network cells (110) of a self-organizing cellular mobile communications network, comprising: retrieving (605) a current configuration (205) of network cells (110, 115) currently deployed on field, including modifiable parameters; exploring (610, 620) different configurations of the network cells, each differing from the retrieved current configuration and from other different configurations by a change in the value of at least one of the modifiable parameters of at least one network cell; evaluating (625) the explored different configurations of the network cells. When a suitable goodness is assessed for a certain configuration of network cells, said new configuration of network cells is automatically deployed on field by modifying one or more of the modifiable parameters of network cells.
Abstract:
In wireless communication networks, especially in WPAN/WSN networks, there is a need to limit power consumption of network nodes; in asynchronous duty-cycled networks special MAC protocols are used for this purpose. According to the present invention, a source node (N1) estimates not only the schedule time offset of the destination node (N2) but also the clock drift of the destination node (N2); in this way, the source node (N1) may choose very accurately the transmission start time of an information packet to this destination node (N2) so that typically only one very short preamble needs to be transmitted. The estimation of time offset and clock drift between two nodes (N1, N2) is achieved through one or more previous transmissions between these two nodes (N1, N2); in particular, information relating to these parameters are transmitted from the destination node (N2) to the source node (N1) in reply to a preamble transmitted by the source node (N1) to the destination node (N2).

A method for providing a wireless communication network for a smart device (105), wherein the smart device comprises wireless communication circuitries (210), is proposed. The method comprises: analyzing information regarding a plurality of hotspots (120a, 120b) in a geographic area (100) wherein the smart device is deployed, each hotspot being capable of establishing one or more wireless communications within a predetermined range; based on said analyzing, estimating an extent of coverage of the wireless communication network provided by the plurality of hotspots; based on said estimating, checking (410, 415, 435, 440) whether at least one hotspot in the geographic area is able to provide wireless communication to the smart device. If at least one hotspot in the geographic area is able to provide wireless communication to the smart device, configuring (420, 465) the at least one hotspot to provide wireless communication to the smart device, else, if no hotspot in the geographic area is able to provide wireless communication to the smart device, modifying (425,430, 455,460,475) an operating behavior of at least one selected hotspot in order to provide wireless communication to the smart device. Said modifying an operating behavior of at least one hotspot comprises: selecting at least one hotspot (120a, 120b) from the plurality of hotspots; sending (425, 460) a request for modifying an operating behavior of the at least one selected hotspot in order to provide wireless communication to the smart device, and verifying that the operating behavior of the at least one selected hotspot has been modified as requested, e.g. rewarding (475) the at least one selected hotspot with an incentive once it is ascertained that the operating behavior of the at least one selected hotspot has been modified as requested.

Abstract:
According to the present invention, a wireless network comprises permanently powered routing nodes (AOR) and intermittently operating routing nodes (SR); a polling procedure is used for transferring routing and data information packets from a permanently powered routing node (AOR) to an intermittently operating routing node (SR). In particular, when said permanently powered routing node (AOR) has to transmit an information packet to said intermittently operating routing node (SR) it stores said information packet into a memory, it waits until said intermittently operating routing node (SR) is able to receive information packets and then it transmits said information packet to said intermittently operating routing node (SR), and when said intermittently operating routing node (SR) has to transmit an information packet to said permanently powered routing node (AOR) it transmits immediately said information packet to said permanently powered routing node (AOR).
