    Abstract: A method for managing nodes of a network includes receiving 702 location information from each of a plurality of nodes in a network, where at least one node is moving relative to another node of the network. The method then includes converting 704 the received location information for each node into a corresponding network address 500. The corresponding network address is based on a hierarchical cell-based partitioning scheme. The method further includes identifying 706 a target region for a given node of the network based on a plurality of routing paths. The target region encompasses two or more nodes in the network that are next hops for the given node and that have a common segment in the corresponding network addresses. The method then includes sending 708 forwarding rules to one or more nodes in the network. The forwarding rules includes the common segment to identify the next hops for the given node.

    Abstract: A method and an antenna system are provided for a high-altitude platform (HAP) (102, 200, 400, 603) configured to move in a pattern (604) in the stratosphere to provide coverage to a region of interest and compensate for HAP movement relative to the region of interest. HAP movement is monitored (905). When it is determined that the HAP has moved relative to the region of interest (910) and, based on the relative movement, a first one of a plurality of antennas in the HAP is no longer able to cover a selected portion of the region of interest (915), an antenna array switching circuit in the HAP is used to adjust beams transmitted by the antennas by switching to a second one of the plurality of antennas to cover the selected portion of the region of interest, such that the communication services provided to the region of interest are not interrupted due to the movement of the HAP (920).

    Abstract: An information processing method implemented by a computer. The information processing method includes the step of acquiring an internal parameter value regarding a biological characteristic of fish, an external parameter value regarding a surrounding environment characteristic of the fish, and a shoaling parameter value regarding a shoaling characteristic that is a behavior of one fish with respect to other fish, and the step of generating a simulation image including a behavior of each fish in a fish school based on the internal parameter value, the external parameter value, and the shoaling parameter value that are acquired in the step of acquiring.

    Abstract: An antenna for wireless communication includes a spherical reflector and one or more feeds. The spherical reflector includes an inner portion made of material that reflects radiofrequency (RF) beams, and an outer portion positioned on an edge of the inner portion, the outer portion being made of metamaterials that can be controlled to be reflective of or transparent to RF beams. The one or more feeds are configured to form one or more RF beams reflected off the spherical reflector. In some implementations, the antenna includes one or more processors configured to form one or more RF beams using the one or more feeds, and control at least a part of the outer portion of the spherical reflector to reflect an RF beam of the one or more RF beams or be transparent to the RF beam based on the one or more RF beam.

    Abstract: The technology relates to simulating a dynamic hybrid network. A method for simulating a dynamic hybrid network includes modeling a transmission supply of a mesh network of moving stations on aerial vehicles in flight at each time step in a time series, modeling capacity demand as a function of user distribution data and user behavior data, and computing an aggregate network metric for the dynamic hybrid network including throughput. A method for optimizing throughput of a dynamic hybrid network includes modeling a dynamic hybrid network, including a transmission supply of a mesh network of moving stations, modeling capacity demand as a function of user distribution data and user behavior data, and computing an aggregate network metric; then providing feedback to a controller and causing a change to a station in the network to increase throughput.
