Abstract:
A system and method for improving a current wireless communication route, between a source node and a destination node in an on-demand wireless communication network, enables the current communication route to be improved even when the current route has not failed. The method includes analyzing at a local node a packet transmission from the source node, the packet transmission comprising a current route metric (step 705). The local node then determines that it can provide an improved wireless communication route, between the source node and the destination node, having a better route metric than the current route metric (step 710). A route improvement message is then transmitted from the local node to the source node (step 740).

An loT 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 (loT) device and an loT service over one or more primary communication channels; one or more secondary communication interfaces to establish a connection between the loT device and the loT 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 loT device and the loT service over one of the secondary communication channels; the secondary communication interface to exchange data between the loT device and the loT service over the secondary communication channel.

Abstract:
Certain aspects of the present disclosure provide techniques for support response-based resource management. A UE may determine an uplink response to be transmitted in response to a downlink transmission by a first TRP participating in CoMP to the UE with a second TRP. The first UE may select which of the first TRP or the second TRP to transmit the uplink response to, based at least in part on the determined uplink response and may transmit the uplink response to the selected first or second TRP.
Abstract:
The present invention relates to a method for operating a communication apparatus in a network comprising a plurality of communication nodes, upon reception of a message at the communication apparatus, the communication apparatus starting a retransmission delay being selected at random from a retransmission delay interval, said retransmission delay interval being dependent on at least one of a status of the communication apparatus and a property of the received message, the communication apparatus monitors retransmissions of said message by other communication nodes during said retransmission delay and the communication apparatus transmitting a retransmission of said message at the expiry of said retransmission delay if a statistic based on the retransmissions of said message by other communication nodes is below a threshold.
Abstract:
Techniques related to a localized routing approach are generally described where the number of transmissions, the maximum number of transmission per node, effective bandwidth, the latency, overall energy consumption, the maximum energy consumption, or other individual or composite objective in a wireless network may be optimized. The localized routing approach may use a metric that combines immediate progress benefit and expense with a statistics-based forward looking estimation of future routing properties and cost. The protocol may also employ a combination of probabilistic and deterministic mechanism to detect and escape local minima.
Abstract:
The mobile ad-hoc network includes a plurality of mobile nodes connected together by a plurality of wireless communication links. The method (FIG. 2) and system for monitoring link quality includes, at each node, recording transmission information for transmissions on links to neighboring nodes (102), calculating a packet error rate for each of the links to the neighboring nodes based upon the recorded transmission information (104), and determining link quality for each of the links to the neighboring nodes based upon the calculated packet error rate (106). The transmission information preferably includes packet size transmitted data, packet size received data, collision data and/or retry data.
