Abstract:
Methods and apparatus for routing data packets in a communications network, such as a packet-switched network (e.g. an IP network). Instead of, or in addition to, conventional routing techniques such as longest prefix matching, the disclosure provides a method by which a network node can determine whether to defer transmission of a particular data packet based on geographical location and velocity data. Particularly for data that can tolerate high latency, this will serve to reduce consumption of network resources without adversely impacting user experience.
Abstract:
Cluster management techniques for wireless data links are described. According to some such techniques, a wireless communication device may maintain proximity information for consideration in conjunction with assigning NAN data links to NAN data clusters. In some embodiments, a wireless communication device may store proximity information for a given NAN data link in an NDL attribute associated with that NAN data link, and may store proximity information for a given NAN data cluster in an NDC attribute associated with that NAN data cluster. In various embodiments, two wireless communication devices may utilize/consider such proximity information in conjunction with assigning a newly-created NAN data link to a NAN data cluster. In some embodiments, two wireless communication devices may utilize/consider such proximity information in conjunction with transferring an extant NAN data link from one NAN data cluster to another NAN data cluster.

Abstract:
Embodiments relate to methods, apparatuses, a mobile communication system and computer programs for updating forwarding information. At least some embodiments provide a method for updating forwarding information within a subset of a plurality of infrastructure entities (100) of a mobile communication system (300). The forwarding information indicates a route for user data traversing the subset of infrastructure entities to the mobile transceiver (200). The method comprises obtaining (12) a paging request for the mobile transceiver (200). The method further comprises providing (14) information on a location for the mobile transceiver (200) based on the paging request. The method further comprises forwarding (16) the information on the location to the plurality of infrastructure entities (100) along an updated route. The method further comprises updating (18) the forwarding information within the subset of infrastructure entities according to the updated route.
Abstract:
Computer-implemented methods, computer software, and computer systems for handling consumer mobility in an information-centric networks (ICN). A pending interest table (PIT) including one or more PIT entries is maintained by an attachment point (AP) of a user equipment (UE) in the ICN. Each PIT entry identifies unsatisfied data requested by the UE.The data requested by the UE are specified in one or more interest packets that were previously received by the AP. An interest packet is received at the AP. The interest packet includes an identifier (ID) of a UE and a name of data that the UE requests. A PIT entry is identified by the AP. The PIT entry includes the name of the data requested by the UE in the interest packet. An index mapping the UE to the PIT entry is generated by the AP based on the ID of the UE.
Abstract:
A linear wireless sensor network includes nodes having monotonically varying node identifiers along each branch. The network identifiers enable the nodes to forward packets without use of routing tables. Low duty cycle wireless communication protocols enable packets to be routed to all nodes of very large networks while consuming very little electrical power. Broadcast, rather than unicast, transmissions between nodes take advantage of favorable signal propagation conditions to forward messages using largest possible hops, skipping over nodes when possible, as well as automatically adapting to time- or spatially-varying conditions. A group of packets is broadcast and forwarded by a most distant receiving node that received all packets of the group. A receiving node's clock is automatically adjusted, based on which packet(s) of a group of packets was received. A sending node synchronizes near-by receiving nodes. Nodes are provisioned over-the-air, with built-in scheduling. Health and welfare information piggybacks on other traffic.
Abstract:
Examples disclosed herein provide for the detection of an orientation of devices with respect to each other. Based on the orientation, one of the devices may route signals between wireless communication units of the devices, so that wireless communication units from one of the devices to make contact with the other device are properly mapped to input/output ports on the other device.
