摘要： According to an embodiment, a communication system includes a plurality of nodes that forms a wireless multi-hop network. One of the nodes includes a processor and a wireless communication controller. When receiving a packet including path information that indicates a parent-child relationship of transfer nodes included on a network topology from a source node to a destination node, the processor is configured to determine whether or not at least one of its own node and a neighboring node existing near the own node is included in the path information as the transfer node. When at least one of the own node and the neighboring node is included in the path information, the wireless communication controller is configured to transfer the packet.

摘要： According to an embodiment, a communication system includes a plurality of nodes that forms a wireless multi-hop network. Transmission timings of network advertising packets transmitted from the plurality of nodes are controlled based on a transmission schedule in which each of the plurality of nodes has one transmission cell at a location different from other nodes. One of the nodes includes a processor and a wireless communication controller. The processor determines a transmission timing of the corresponding network advertising packet based on the transmission schedule. The wireless communication controller transmits the network advertising packet at the transmission timing.

摘要： According to an embodiment, a device sends, to an access point device, a network access authentication request issued with respect to a first network. An authentication server device includes a first device-authentication processing unit that, in response to the network access authentication request, performs an authentication operation based on first-type authentication information. The access point device includes a transfer processing unit and a second device-authentication processing unit. When second-type authentication information is not included in the network access authentication request, the transfer processing unit transfers the network access authentication request to the authentication server device. When the second-type authentication information is included in the network access authentication request and when an authentication operation in the access point device is enabled, the second device-authentication processing unit performs an authentication operation based on the second-type authentication information.
