To predict a first metric for a station in a wireless network, at least one hardware processor in a prediction device or at least one hardware processor in a first access point associated with the station, determines that a recent measurement of a second metric correlated with the first metric has hanged compared to a previous measurement of the second metric, the second metric for the station and measured by the first access point; and in case the second metric has changed, prediction of the first metric for the station is triggered. The first metric can be a signal strength of a signal received by the station from a second access point not associated with the station and the second metric a signal strength of a signal received by the first access point from the station.

Device and method for prediction of metrics in a wireless network with multiple access points

System and techniques for a hierarchical resource constrained networks are described herein. Device participating in the network are divided into groups. These groups correspond to vertices in a routing graph. A leader is selected amongst the devices in each group to function as a routing node connecting to other vertices of the routing graph. Client devices attach to leaf vertices in the routing graph. To reduce overhead in placing devices into the routing pools, a distributed hash table (DHT) can be used. Here, the routing pools can be given DHT IDs based on, for example, a structure of the routing graph. Device DHT IDs are used to assign them to the routing pools based on a distance metric. Routing, in this arrangement, can use the DHT IDs to efficiently compute routing pool hops when routing messages. This arrangement works well for publication-subscription (pub-sub) services.

Hierarchical resource constrained network

In a wireless network with a plurality of access points, device calculates, for each wireless station in the network, a score based on at least an availability of the wireless network for the wireless station, combines the scores for the wireless stations into a current network score for a present configuration of the wireless network, calculates a plurality of predicted network scores corresponding to predicted network configurations with one wireless station moved to a different access point than in the present configuration, each predicted network score being a combination of the scores for wireless stations not moved in the predicted network configuration and a predicted score for the wireless station moved in the predicted network configuration, selects one of the current network score and the plurality of predicted network scores that satisfies a criterion; and, in case a predicted network score is selected.

Device and method for holistic steering of stations in a wireless network with multiple access points

A device comprising at least one hardware processor obtains a bandwidth for a communication from a station in a wireless network and a signal strength for the communication from the station, and determines that the communication is a communication related to network maintenance in case the bandwidth is below a first value and an expected bandwidth based on the signal strength is above a second value, and that the communication is a data communication in case the bandwidth is below the first value and the signal strength is below the second value, in case the communication is a data communication, the at least one hardware processor can determine that the station is active.

Device and method for determination of whether a frame is a management frame or a data frame

To predict a first metric for a station in a wireless network, at least one hardware processor in a prediction device or at least one hardware processor in a first access point associated with the station, determines that a recent measurement of a second metric correlated with the first metric has changed compared to a previous measurement of the second metric, the second metric for the station and measure by the first access point; and in case the second metric has changed, prediction of the first metric for the station is triggered. The first metric can be a signal strength of a signal received by the station from a second point not associated with the station and the second metric a signal strength of a signal received by the first access point from the station.

In today's network management world, there are various solutions that collect data and presume to identify events impacting the QoE of the end-users. However, such solutions usually do not try to address the question of whether the end-users are actually impacted. These solutions usually look at certain types of known problems and try to detect if that problem exists in the end-user's network, and from that they conclude that the end-user might be impacted. The method according to an embodiment of the invention enables to proactively identify that an end-user is actually experiencing an event impacting the QoE in his home network. The proposed solution enables the detection of event affecting an end-user's network, regardless of the type of the network and without looking for specific issues. This knowledge may be a valuable asset of an Internet Service Provider which may fix issues quicker or mitigate end-users' dissatisfaction.

Method for identifying an event impacting the QoE of an end-user of a network equipment

When a failure is detected of a communication link between a wireless access point and a service provider providing services to devices in proximity of said wireless access point, a probe request message is broadcasted on one or more wireless communication channels. The broadcasted probe request message includes a particular payload enabling the message to be identified as being a distress message reporting a failure of the communication link. Another wireless access point within wireless communication reach receiving a distress message may transfer a communication link failure report to the service provider in place of the wireless access point of which the communication link fails.
