Methods, systems, and devices for relay path selection in wireless communications are described, where multiple relay paths are available between a source and a destination. A first node (e.g., a source node or destination node) may determine reference signal resources for a set of reference signals to be transmitted between the first node and a second node through a corresponding relay path of a set of relay paths. The first node may receive the set of reference signals measure one or more parameters for each reference signal. Alternatively, the first node may transmit the set of reference signals and receive an indication of one or more measured parameters from the second node. The first node may determine a set of end-to-end metrics for the set of relay paths, and select a relay path for communications with the second node based on the set of end-to-end metrics.

Automated processes, computing systems, devices and other aspects of a wireless data network are described. According to various embodiments, message flooding in the wireless network is reduced through the use of “dummy” messages from the radio unit (RU) to the distributed unit (DU) and/or layer two (L2) switch. The dummy messages prevent timeout of the RU's data in the L2 switch's routing tables, thereby prolonging the period of time that the L2 switch is able to more efficiently direct subsequent traffic toward that particular device.

A communication method includes receiving a first packet from a second node, where the first packet includes an identifier of the second node, a first identifier, and an identifier of a receiving node; determining, based on the first packet, whether the first node is the receiving node; and determining a first routing table based on the first packet in response to a determination being made that the first node is not the receiving node, where the first routing table is used for data routing to the receiving node.

A control signal used for selecting a parent node in a tree route is transmitted from a first wireless node among a plurality of wireless nodes which constitute a backhaul network. Second wireless nodes each select, as a parent node, one of transmission source nodes of a plurality of control signals on the basis of an index indicating the radio wave propagation quality of a route through which each of the control signals received from different route has been propagated. Fixed wireless nodes among the second wireless nodes each transmit the received control signal to the other second wireless nodes, and a movable wireless node among the second wireless nodes terminates the received control signal.

A communication control device that controls a plurality of communication devices in a network system includes: a receiver, a processor and a transmitter. The receiver receives a request pertaining to use of data generated by the data generation device from a user device. The processor determines a route between the data generation device and the user device, specifies first and second communication devices that are implemented at both ends of an overlapped route between a first route corresponding to a first request and a second route corresponding to a second request, and determines, based on the first request and the second request, a function to be executed by at least one of the first and second communication devices. The transmitter transmits an instruction including information for identifying the function determined by the processor to at least one of the first and second communication devices.

A server-based environment for reporting a status of a security, monitoring and automation controller is provided. Detecting cessation of an always-on persistent network connection between the SMA controller and the server is also provided. Reporting the cessation of the network connection to an end user and defined others is further provided. A further aspect provides for automatically reporting an alarm event to a central station, the end user, and others, in the event the cessation of the network connection occurs while the SMA controller is armed and after a zone fault event, and not receiving a disarm notification prior to expiration of a preset entry delay.
