Abstract: In one embodiment, a cloud-based service instructs one or more networking devices in a local area network (LAN) to form a virtual network overlay in the LAN that redirects traffic associated with a particular node in the LAN to the service. The service receives multicast or broadcast traffic sent by the particular node in the LAN and redirected to the service via the virtual network overlay. The service identifies a group of nodes in the network that are to receive the traffic sent by the particular node, based in part by profiling the traffic associated with the particular node. The service sends the traffic sent by the particular node to at least one networking device in the LAN with an indication of the identified group of nodes in the network that are to receive the traffic sent by the particular node. The at least one networking device forwards the traffic sent by the particular node to the nodes in the identified group.

Abstract: The technique herein optimizes delivery performance from a content delivery network (CDN) edge node, preferably by using knowledge of radio link allocation behavior. According to the technique herein, an IP address of a cellular end user (or equivalent) is recognized by the CDN edge. Then, preferably by tracking idle times both in consecutive downloading bursts in the end user session and in an on/off style radio link allocation pattern, the CDN edge adjusts transport layer network protocol parameters. The approach (which leverages the cross-layer intelligence obtainable from existing CDN infrastructure) thus enables the transport layer protocol implemented at the edge to optimize the delivery performance over the cellular mobile network.

Abstract: Efficient and reliable transmission of information from sparse sources over wireless channels in wireless signal networks (WSNs). WSN nodes employ an “integrated signal representation-to-modulation” scheme to describe a sparse signal acquired from a sensor so as to ensure robustness against channel errors across a wide range of signal to noise (SNR) values in a rateless fashion. In one example, sparse signal samples are linearly transformed such that the total number of bits representing the sparse signal is reduced. The linearly-transformed signal samples are directly mapped to a modulation constellation to provide a succession of modulation symbols. A carrier wave is modulated in phase and/or frequency according to the succession of the modulation symbols to generate an encoded carrier wave representing the sparse analog signal. In one aspect, an order of the modulation constellation is based on the precision (e.g., number of bits) of each of the linearly-transformed signal samples.
