Abstract: In one embodiment, a device in a wireless network selects a transmission rate for one or more packets to be sent, based on a received signal strength indicator value. The device makes a determination that the one or more packets should be compressed, based on the transmission rate selected by the device. The device applies, based on the determination, stateless offline dictionary compression to the one or more packets, to form a compressed stream of one or more packets. The device sends the compressed stream via the wireless network and using the transmission rate selected by the device.

Abstract: In one embodiment, a controller predicts an occurrence of an event in a wireless network, based in part on a movement of a mobile node of the wireless network. The controller initiates application of network-layer forward error correction encoding to a stream of packets to be sent during the event between the mobile node and an access point of the wireless network, to form one or more encoded packets. The controller causes the one or more encoded packets to be transmitted in conjunction with the stream of packets during the event. The controller ceases application of the network-layer forward error correction encoding after the event has occurred.

Abstract: In one embodiment, a mobile node having a first radio and a second radio applies stateless offline dictionary compression to an uncompressed stream of packets, to form a compressed stream of packets. The first radio of the mobile node communicates with a first access point of a wireless network and the second radio of the mobile node communicates with a second access point of the wireless network. The mobile node selects the first radio to send the uncompressed stream of packets and the second radio to send the compressed stream of packets. The mobile node sends, via the first radio, the uncompressed stream of packets to the first access point over a first wireless path. The mobile node sends, via the second radio, the compressed stream of packets to the second access point over a second wireless path.

Abstract: In one embodiment, a device identifies a plurality of access points of a wireless network. The device also identifies a plurality of mobile nodes of a mobile system. The device establishes a first label-switched path in the wireless network that comprises a wireless link between a first mobile node in the plurality of mobile nodes and a first access point in the plurality of access points. The device establishes a second label-switched path in the wireless network that comprises a wireless link between a second mobile node of the mobile system and a second access point in the plurality of access points.
