Disclosed are electronic device, a network system, and a control method thereof. An electronic device according to the present disclosure comprises a memory, a communication interface, and a processor which: when receiving network connection information including a hop count from a first external device connected to a network, updates the network connection information to reduce the hop count, and stores the same in the memory; and when receiving a beacon message from a second external device that is not connected to the network, transmits the updated network connection information to the second external device by using the communication interface so that the second external device can be connected to the network.

Methods and systems for accessing networks prohibit uncontrolled communications over a designated network. In some aspects, a method of controlling network access is disclosed. The method comprises transmitting, by a first access point, a first beacon over a first network to a station, the first beacon including information allowing the station to associate with the first access point. The method also comprises receiving a probe request at the first access point over the first network from the station, the probe request including a request for rules for associating with a second network. The method additional comprises generating a probe response to include the rules regarding associating with the second network, wherein the rules do not permit uncontrolled communications over the second network. The method further comprises transmitting the probe response from the first access point to the station over the first network.

A network construction method, a routing method and device of mobile ad-hoc networks are provided. The mobile ad-hoc network includes a plurality of nodes, each node communicating with its neighbors via communication links. The routing method comprises the following steps: each node identifying a link quality with each of its neighbors by providing marks based on a hysteresis-based link quality marking mechanism; each node identifying a link operationality with each of its neighbors by evaluating a score calculated from the marks; and each node reconstructing routes with its neighbors by filtering route construction messages related to the link operationality of the neighbors.

A wireless network association and authentication system includes an access point that is coupled to an authentication server via a first wireless network. The access point receives, from a first user device that associates with the access point, a first request for access to a second wireless network provided by the access point that is coupled to a wide area network through the first wireless network. The first request includes first authentication information. The access point provides the first request that includes the first authentication information to the authentication server via the first wireless network and receives a first authentication response from the authentication server via the first wireless network. In response to the first authentication response indicating that the first user device is authenticated, the access point provides the first user device access to the second wireless network.

A user equipment (UE) in a wireless network employs orthogonal polyphase codes for encoding data symbols to generate a set of coded data symbols, which are modulated onto Orthogonal Frequency Division Multiplex (OFDM) subcarrier frequencies assigned for use by the UE, and the resulting OFDM signal is transmitted to a base station in the wireless network. The orthogonal polyphase codes include pairs of orthogonal polyphase codes that are complex conjugates of each other.

Automatically communicating information related to a user computing device from a central computing system to a transaction computing system prior to initiation of a transaction between the user computing device and the transaction computing system comprises a digital wallet application and a central computing system. A digital wallet application receives a beacon signal from a transaction computing system indicating the specific identification of the terminal with which the user intends to conduct a transaction. The user computing device communicates the terminal identification to the central computing system. The central computing system communicates customer data, such as loyalty information and offers, to the transaction computing system associated with the terminal. The transaction computing system communicates the customer data to the terminal. When the user taps the user computing device to initiate the transaction, the terminal provides any benefits associated with the customer data.

A non-personal basic service set control point/access point (non-PCP/AP) communication apparatus includes a reception circuit, an estimation circuit, and a transmission circuit. The reception circuit receives a Directional Multi-Gigabit (DMG) Beacon frame including a sector sweep (SSW) field, the SSW field including a Parameter subfield indicating a value obtained by using a transmission Equivalent Isotropic Radiated Power (EIRP) of a PCP/AP communication partner apparatus and a reception antenna gain of the PCP/AP communication partner apparatus. The estimation circuit estimates an expected reception power at the PCP/AP communication partner apparatus by using the value of the Parameter subfield, and checks inequality between the estimated expected reception power and a receiver sensitivity value. The transmission circuit transmits a frame for Association Beamforming Training (A-BFT) if the estimated expected reception power is larger than the receive sensitivity value.

Method for operating a network node of a wireless digital data network based on broadcast layer-2 periodic frames, wherein said network is composed by a plurality of network nodes, wherein each network node is either a mobile node equipped with an on-board unit (OBU) node, or is a static node equipped with a road-side unit (RSU) node, said method comprising a current network node of the plurality of network nodes carrying out the following steps: periodically broadcasting a Network Status Information (NSI) frame which comprises: the node identifier and a type of node of the current network node; receiving broadcasted NSI frames from neighbouring network nodes of the plurality of network nodes reachable by the current network node through wireless communication; for any one received NSI frame, storing the received NSI frame in an entry in a NSI table (NSIT) if the received NSI frame was the first received NSI frame from a neighbouring network node, or otherwise, if the received NSI frame was not the first received NSI frame from the neighbouring network node, updating a previously stored NSIT entry with the received NSI frame; marking as expired or deleting any previously entered NSIT entry after a predetermined period of time has passed after receiving or updating said any previously entered NSIT entry. Also an electronic network node of a wireless digital data network, wherein said network node is programmed to carry out the method.

A set of rules for assigning a transmission number to one or more computing devices is received. An indication from a first computing device is received. The indication includes a request for a transmission number. The transmission number for the first computing device is determined using the set of rules and a transmission window. The transmission number is transmitted to the first computing device.

An embodiment of the invention may include a method, computer program product and computer system for detecting a device. The embodiment may include a computing device that determines a Universally Unique Identifier (UUID) of a beacon of a second device. The computing device may determine a first location of the first device. The computing device may determine whether the UUID of the beacon of the second device matches a UUID in a list of UUIDs, where each UUID in the list of UUIDs corresponds to a beacon associated with a device. The computing device may transmitting the UUID of the beacon of the second device and the first location to a third device, based on determining the UUID of the beacon of the second device matches an entry in the list.
