Method and system for operating a vehicular data network based on a layer-2 periodic frame broadcast, in particular a routing protocol
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 neighboring 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 neighboring network node, or otherwise, if the received NSI frame was not the first received NSI frame from the neighboring 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.
INFORMATION PROCESSING APPARATUS AND METHOD AND PROGRAM FOR CONTROLLING INFORMATION PROCESSING APPARATUS
An information processing apparatus is configured to acquire the history of access points previously connected to the information processing apparatus and to enable selection, based on the acquired history, an access point to be set for a device. Based on information on an access point selected from the displayed access points, the information processing apparatus notifies the device of a setting for connection to the selected access point.
APP RECOMMENDATION USING CROWD-SOURCED LOCALIZED APP USAGE DATA
Applications may be tagged with location data when they are used. Mobile device may anonymously submit application usage data. Aggregated application usage data from many mobile devices may be analyzed to determine applications that are particularly relevant to a given location (i.e., exhibiting a high degree of localization). Analysis may include determining the application usage intensity, whether hotspots exist or not at a given location, the spatial entropy of a particular application, the device populations in a particular area, etc. Based on the localized application analysis, applications may be ranked according to local relevance, and, based on this ranking, application recommendations may be provided to a user.
Wireless relay station, wireless relay system, control circuit, storage medium, and wireless relay method
A wireless relay station to be included in a ladder-type wireless relay network along a moving route of a moving object includes a relay control unit that includes station identification information in the wireless relay network assigned sequentially along the moving route to each of the wireless relay stations included in the wireless relay network and deployed along the moving route, configures and updates, using a first routing table that provides an address of a destination wireless relay station, a second routing table including the address, the station identification information, and an information update time, being associated with one another, of the destination wireless relay station, and provides control to share, among the wireless relay stations included in the wireless relay network, the second routing table configured and updated by each wireless relay station; and a relay communication unit that performs wireless relay communication with other wireless relay stations.
System and method for efficient use of flow table space in a network environment
A method is provided in one example embodiment and includes determining an action to be performed with respect to a packet corresponding to a new flow received at a network device and determining whether a new entry comprising an indication of the determined action can be added to a flow table of the network device. The determination of whether a new entry can be added to the flow table is made with reference to reservation information specified in a port profile associated with the new flow. Responsive to a determination that the new entry can be added, the new entry is added to the flow table. In one embodiment, determining whether the new entry can be added comprises determining whether an existing entry can be aged out based on the reservation information specified in the associated port profile.
A METHOD FOR MIGRATING NODES IN A DISTRIBUTED NETWORK TO A CENTRALIZED NETWORK
A method (500) for migrating two or more nodes (400) in a distributed wireless network to a centralized wireless network, the method (500) comprising the steps of sending (S501) one or more parameters related to the centralized wireless network by a first bridge device (200) in the centralized wireless network to a second bridge device (300) in the distributed wireless network; collecting (S502) topology information among the two or more nodes (400) by querying the two or more nodes (400) in the distributed wireless network; determining (S503) a sequence list for requesting the two or more nodes (400) to join the centralized wireless network based on the topology information; requesting (S504) the two or more nodes (400) to join the centralized wireless network according to the sequence list.
