摘要： A method of operating a node device (20) in a network (10) of communicatively interconnected node devices wherein a node device (20) is arranged to transmit a message once in said network (10), the node device (20) comprising a host part (30) and a controller part (40). The host part (30) is arranged for maintaining a list (31) identifying messages received at the node device (20) and the controller part (40) is arranged for storing messages to be transmitted by the node device (20) in a cache buffer (41). The method comprises the steps of removing, by the controller part (40), a message from the cache buffer (41), forwarding, by the controller part (40), to the host part (30), upon removal of the message, an update message identifying the removed message, and updating, by the host part (30), based on the update message, the list of messages (31). A corresponding node device (20) arranged for performing a method according to the present disclosure and a computer program product are also presented herein.

摘要： A method performed by a method performed by a network node for transmitting a message in a mesh network to a destination node is provided. The network node transmits (503) the message addressing the destination node. During a first time interval, the network node scans (504) if any message considered to be a relayed copy of the transmitted message is received. When no message considered to be a relayed copy of the transmitted message is received during the first time interval, the network node repeats the transmitting (505) of the message addressing the destination node. When a message considered to be a relayed copy of the transmitted message is received, the network node decides (506) to not repeat to transmit the message addressing the destination node.

摘要： A method by an end node (102) operating in a Mesh communications network (100) is described herein. The end node (102) monitors (601), a first channel, for transmissions of first information from one or more relay nodes (103) operating in the network. The first information indicates transmission, from the one or more relay nodes (103), of second information on a second channel associated with the first channel. The second information indicates transmission, from the one or more relay nodes (103), of third information on a third channel. The third channel is associated with the second channel and the first channel. The end node (102) then determines (603), based on the second information, time periods during which no transmission of the third information is predicted to be performed by the one or more relay nodes (103) on the third channel. The end node (102) then schedules (604) a transmission of fourth information in a fourth channel during the determined time periods.

摘要： Systems and methods related to traffic flow prediction in a wireless network are disclosed. In one embodiment, a computer-implemented method comprises collecting training data comprising Internet Protocol (IP) addresses extracted from packets for traffic flows in a wireless network and one or more actual traffic type related parameters for each of the traffic flows. The method further comprises training heavy-hitter IP address encodings based on the extracted IP addresses and encoding the extracted IP addresses using the trained heavy-hitter IP address encodings. The method further comprises training a traffic type predictor of a traffic flow predictor based on the encoded IP addresses and the one or more actual traffic type related parameters for each of the traffic flows, where the traffic type predictor is a learning model that maps encoded IP addresses to one or more predicted traffic type related parameters.

摘要： Methods and systems for providing virtual beacons are presented. According to one aspect, a method for providing a virtual beacon at a first location comprises transmitting, by a transmitter at a second location geographically different from the first location, an information signal using a transmit power level, Pj, and including an advertised transmit power level, PA, both selected to be indicative of a distance, d, between a location of a receiver of the information signal and the first location. The signal transmitted from the second location emulates a signal that would have been produced by a beacon located at the first location. The information signals may be aimed at one or more User Equipments (UEs), and/or may be focused on one or more specific target locations rather than on individual UEs.
