| 20080232389 | Distributed Overlay Multi-Channel Media Access Control for Wireless Ad Hoc Networks - Systems and methods for distributed overlay multi-channel MAC for wireless ad hoc networks are described. In one aspect, the systems and methods divide channel frequencies defined by a wireless network protocol into a single home channel and multiple guest channels that are orthogonal to the home channel. Each of the network nodes in the ad hoc network operates on the home channel for respective variable and overlapping amounts of time to maintain network connectivity with other respective network nodes. Additionally, each of the network nodes determines whether and when to switch from the home channel to a particular guest channel of the guest channels for a variable amount of time to increase data throughput over one or more corresponding communication links in the ad hoc network with other network node(s). | 09-25-2008 |
| 20090274043 | MULTI-LEVEL INTERCONNECTION NETWORK - A method and system for providing a multi-level interconnection network is provided. A multi-level interconnection network comprises basic cells that are aggregated into higher level cells at each level of the network. At the first level, the basic cells are aggregated into first level cells. Each first level cell is an aggregation of a number of basic cells that is one more than the number of devices in a basic cell. The basic cells of a first level cell are fully connected; that is, each basic cell has a first level link or connection to each other basic cell. In a first level cell, each device of a basic cell has a first level link to each other basic cell. The multi-level interconnection network has higher level cells that are aggregations of lower level cells in a similar manner. | 11-05-2009 |

| 20100153523 | SCALABLE INTERCONNECTION OF DATA CENTER SERVERS USING TWO PORTS - Large numbers of commodity servers in a data center may be inexpensively interconnected using low-cost commodity network switches, a first network port on each commodity server, a second network port on each commodity server, and a traffic-aware routing module executed on each commodity server. Connecting two or more commodity servers via the first network ports on each server to a commodity network switch forms a unit. Connecting two commodity servers in different units forms a group. Each unit has a direct connection via a second network port on a commodity server in the unit to another unit. Each group may have a direct connection via a second network port on a commodity server in the group to another group. Traffic-aware routing modules executed on each commodity server determine routing of data between servers and balance traffic across the first and second ports. | 06-17-2010 |
| 20100172274 | Energy saving using cellular footprint for mobile device Wi-Fi access point discovery - Described is a technology in which a Wi-Fi enabled mobile computing device conserves power by only selectively scanning to discover a potential access point for connecting. In one aspect, a cellular footprint, comprising the cellular tower identifier(s) and corresponding signal strength information, determines whether to perform or delay the Wi-Fi scan. The footprint may be used to detect mobile user location changes and compare with history, so as to delay scanning when the device has not sufficiently moved, or delay scanning when the history indicates little chance of a successful discovery/connection at the current location. | 07-08-2010 |
| 20100172275 | Energy Efficient Device Discovery with Short-Range Radios - Described is a technology in which a Wi-Fi enabled mobile computing device conserves power by only attempting peer discovery at certain times, according to a wakeup pattern. A device time clock is synchronized, such as via a cellular service, a GPS system, or a network to establish the time to awaken. Imprecise synchronization between the devices within a maximum difference is acceptable because the pattern ensures that any two devices are concurrently awake for at least a sufficient time to perform discovery. The awake time may be divided into active and inactive slots, arranged such that an active slot of each device will overlap regardless of when the awake time begins on each device. Also described is using a previously agreed-upon communications channel for subsequent discovery, which may be based upon pseudo-random number generation. | 07-08-2010 |
