Generation and management of a communication path between a plurality of information processing devices are properly performed. An information processing device is an information processing device equipped with a communication unit and a control unit. The communication unit performs exchange of a signal for generation or updating of a multi-hop communication path using wireless communication with another information processing device. In addition, the control unit performs control to change a metric value included in the signal for generation or updating of the multi-hop communication path based on a state of the information processing device.

In one embodiment, a method comprises: receiving, by a network device in a data network, a wireless data packet containing new data; responding to the wireless data packet, by the network device, by initiating a prescribed randomized collision avoidance method requiring the network device to first wait at least a first half of a prescribed minimum contention interval before attempting transmission at a randomized position within a second half of the prescribed minimum contention interval; selectively retransmitting, by the network device, the wireless data packet based on determining, at the randomized position, that the network device has not received a prescribed number of copies of the wireless data packet; and selectively sending, by the network device to a path computation element in the data network, a message requesting membership in a dominating set in response to transmission of the wireless data packet by the network device.

An IoT system and method for selecting a secondary communication channel. For example, one embodiment of an apparatus comprises: one or more primary communication interfaces to establish a connection between an Internet of Things (IoT) device and an IoT service over one or more primary communication channels; one or more secondary communication interfaces to establish a connection between the IoT device and the IoT service over one or more secondary communication channels; a communication interface selection module to determine whether a primary threshold related to connection attempts over the one or more primary communication channels has been reached; in response to detecting that the primary threshold has been reached, the communication interface selection module to attempt to establish a connection between the IoT device and the IoT service over one of the secondary communication channels; the secondary communication interface to exchange data between the IoT device and the IoT service over the secondary communication channel.

A wireless communication apparatus determines the ratio of sockets which are allocated to a first wireless interface using a first communication network and sockets which are allocated to a second wireless interface using a second communication network, on the basis of the radio quality of the first communication network and the radio quality of the second communication network. The wireless communication apparatus generates the sockets in accordance with the determined ratio and performs wireless communication. The wireless communication apparatus measures the amount of traffic through the first wireless interface and the amount of traffic through the second wireless interface in the wireless communication using the sockets which are generated in accordance with the determined ratio. The wireless communication apparatus corrects the number of sockets allocated to the first wireless interface and the second wireless interface on the basis of the measured amounts of traffic.

The present invention relates to a technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and the Internet of things (IoT). The present invention can be used for intelligent services (smart home, smart building, smart city, smart car or connected car, health care, digital education, retailing, security and safety related services, and the like) based on the technology. The present invention provides a method by which a node transmits a signal in a mesh network, the method comprising the steps of: transmitting a packet; receiving at least one packet transmitted from at least one peripheral node except for the node, after transmitting the packet; determining whether the at least one peripheral node has normally received the packet on the basis of the at least one packet; and retransmitting the packet if it is determined that it is necessary to retransmit the packet, on the basis of the determination result.

A wireless communication device of the present invention has a device information storage part that stores device information identifying another wireless communication device that can establish wireless communication. When transmitting data, the wireless communication device attaches transmission source neighboring device information stored in the device information storage part of the device to the data, and transmits the data to another wireless communication device. When receiving data, the wireless communication device stores transmission source device information identifying another wireless communication device having transmitted the data into the device information storage part of the device. The wireless communication device determines whether to relay and transmit the received data to another wireless communication device on the basis of the result of comparison between the transmission source neighboring device information attached to the received data and receiver neighboring device information stored in the device information storage part of the device.

Communication network architectures, systems and methods for supporting a network of mobile and/or static nodes. As a non-limiting example, various aspects of this disclosure provide communication network architectures, systems, and methods for providing dynamic routing and/or selection of communication pathways in a communication network comprising a complex array of both static and moving communication nodes (e.g., the Internet of moving things), for example including a network of autonomous vehicles.

In one embodiment, a device that is protected against a power outage event in a network receives metrics used by a first node in the network to select a routing link to a second node in the network. The device stores the metrics used by the first node to select the routing link to the second node. The device selects a set of one or more of the metrics to provide to the first node during network formation after a power outage event in the network. The device provides the selected set of one or more of the metrics to the first node, wherein the first node uses the provided set to reestablish connectivity to the network.
