摘要： An apparatus includes a base pipe and a fluid control material. The base pipe includes openings, and the fluid control material is mounted to the pipe to control fluid communication through the openings of the pipe. The fluid control material has a permeability that may be changed to selectively control the communication of well fluid through the openings.

摘要： A method and apparatus for channel assignment within an ad-hoc communication system utilizing multiple channels is provided herein. Individual nodes receive and send route-request (RREQ) packets on all channels rather than a single channel. Each route-request packet comprises a first and a second table. The first table comprises a channel state for the link and the second table comprises a channel quality metric for the link. Each node updates the channel state and channel quality tables and forwards them in the RREQ packet as part of the route-discovery process. When channel selection is made, the channel selection is based on the channel state and the channel quality tables.

摘要： Adaptively changing weights for fair scheduling in broadcast environments. In one embodiment, a computer-implemented method allocates bandwidth among a plurality of flows, such as nodes, sharing an output link, such as a network. The method includes adaptively determining a weight for each flow, based on a predetermined criterion, and allocating a portion of bandwidth to each flow proportionally to the weight for the flow. In one embodiment, the predetermined criterion takes into account an input rate of data packets for each flow, while in another embodiment, the predetermined criterion takes into account a queue size for each flow.
