In some implementations, formation of loops between nodes in an RPL network may be avoided. A node that receives a neighbor-discovery message may determine, based on a parent-child status, whether the neighbor-discovery message was received from a parent of the node. If the neighbor-discovery message was received from the parent, the node may transmit an error code to the parent. In addition, the node may determine, based on a comparison of reliability rankings, whether the neighbor-discovery message was received from a node with relatively high reliability, such as a potential grandparent node. If the neighbor-discovery message was received from a high-reliability node, the node may transmit an error code to the high-reliability node. Furthermore, the node may reduce network traffic by withholding a neighbor-detection message from a child node. The node may transmit a response to neighbor-detection messages received from the child node.

A method of acquiring software by a source node in a wireless ad hoc network. The method includes the source node executing application software from which a need to process a particular modality of data is identified, and making a determination that the source node is incapable of processing the particular modality of data. Responsive to the determination, the source node searches a local module repository (MR) of the source node for a software module usable to process the particular modality of data, and responsive to the source node failing to locate the software module in the local MR, broadcasts a request for the software module to neighbor nodes of the plurality of nodes in radio range of the source node. The source node receives the software module from the neighbor node, and uses the software module to process the particular modality of data.

Methods and apparatus for performing device-to-device (D2D) discovery are described. A service discovery process may include a discoverable device (e.g., a wireless transmit/receive unit (WTRU)) sending a discovery request, over a wireless connection, for a radio resource for the purpose of performing a transmission for radio frequency (RF) proximity detection for a given service. The WTRU may receive a discovery response including a configuration for RF proximity detection from a network, which configuration may be associated to the service. The configuration for RF proximity may be received by dedicated signaling, (e.g., physical downlink shared channel (PDSCH)), in particular for a discoverable WTRU. The configuration for RF proximity may be received on a broadcast channel, (e.g., a discovery shared channel (DISCH)), in particular for a monitoring WTRU, and may include one or more service identities, each associated with an RF proximity detection configuration, or a validity information and a measurement configuration.

This disclosure describes methods, devices, and systems related to communicating routing messages using service discovery in neighbor awareness networks (NAN) and further building a routing table for a mesh network. A device may assign a NAN service name to a routing protocol. The device may determine a NAN service discovery frame comprising a routing protocol message of the routing protocol. The device may cause to send the NAN service discovery frame to a second device during a discovery window.

A method of measuring system integrity and robustness to link failure for use with a wireless signaling system is described. The measuring system can calculate the number of unique communication routs available for message transfer between an initiating device and a target device wherein unique routes are non-converging and defined by message source and signal strength data derived from a plurality of system devices.

Device detection in networks with mixed mobility devices is discussed. Devices in the network first determine a discovery mode from a plurality of discovery modes, wherein the determining is based on a mobility state of the wireless device. The device identifies a set of resources associated with the determined discovery mode, wherein each of the plurality of discovery modes is provisioned with separate resources. A discovery signal is transmitted using the identified set of resources according to the discovery mode. Thus, devices with higher mobility will generally send discovery signals more often than devices that are static or semi-static.

In a 5G network, an integrated access and backhaul (IAB) deployment in a 5G network, can enable aggregation of multiple user equipment (UE) bearers into backhaul bearers based on factors such as route information of UE bearers and quality of service of UE bearers. Additionally, reconfiguration of backhaul bearers, based on triggers, such as route changes for UE bearers can increase network efficiency for a 5G or other next generation network.

In one embodiment, a device identifies a plurality of access points of a wireless network. The device also identifies a plurality of mobile nodes of a mobile system. The device establishes a first label-switched path in the wireless network that comprises a wireless link between a first mobile node in the plurality of mobile nodes and a first access point in the plurality of access points. The device establishes a second label-switched path in the wireless network that comprises a wireless link between a second mobile node of the mobile system and a second access point in the plurality of access points.

Devices, networks, systems and methods for coordinating industrial control and monitoring communications on multi-path radio frequency transmission mesh networks include establishing path metrics allowing a respective comparison of a plurality of available communication paths between neighboring radios communicating in the mesh network. Replies to route requests may be delayed based on the path metrics of available paths for message transmission to ensure that the best available connection routes through the mesh network can be understood and utilized.

A communication system may comprise an information processing device and a communication device. Communication between the communication device and the information processing device using the first wireless communication scheme may be performed. The communication device may send the connectable network identification information to the information processing device. Communication between the information processing device and the communication device using the second wireless communication scheme and using the second network may be executed, in case that the first network belongs is not included in one or more networks identified by the connectable network identification information. Communication between the information processing device and the communication device using the second wireless communication scheme and using the first network may be executed, in case that the first network is included in the one or more networks identified by the one or more connectable network identification information.
