20130232253 | PEER-TO-PEER DISCOVERY - A wireless device that discovers other wireless devices for the formation of a peer-to-peer connection may perform a scan that is limited in duration and power consumption. The scan nonetheless is highly likely to discover a device, if a discoverable device exists. In addition, the scan may be performed in compliance with parameters of a peer-to-protocol such that the scan may be readily implemented in a wireless device, in some embodiments even as a firmware upgrade on a wireless network interface card. Parameters of the scan may be adjusted to increase the likelihood that, if the scan completes without discovering a device, no discoverable device exists. The scan may be used in an overall process in which discovery ends or the scan is selectively repeated following an unsuccessful scan, without entering a find phase. | 09-05-2013 |
20140289396 | Detecting Device Presence for a Layer 3 Connection Using Layer 2 Discovery Information - Techniques for monitoring presence of a remote device at Layer 2 that allow reducing power consumption without compromising the device's availability. A device that pairs with a remote wireless device may establish a Layer 3 connection, such as an IP connection, to the remote device to provide services to a user. The Layer 3 connection may be formed over a Layer 2 connection via an access point or as a peer-to-peer wireless connection between the devices. When the Layer 3 connection is not actively used to access the remote device, the Layer 3 connection and the supporting Layer 2 connection (e.g., WI-FI, WI-FI DIRECT™ or BLUETOOTH®) may be terminated and presence of the remote device may be monitored using a Layer 2 device discovery mechanism. The Layer 2 and Layer 3 connections to the device may be reestablished when use of the remote device is desired. | 09-25-2014 |

20140126468 | Determination of Packet Retransmission using Time Threshold - Techniques for determination of packet retransmission using a time threshold are described. In at least some embodiments, information for a packet that is received is compared to information for previously received packets. If the information for the packet matches a previously received packet, a receive time for the packet is compared to a timestamp for the previously received packet to determine if the packet is a retransmission of the previously received packet. In at least some embodiments, packet information associated with different senders can be stored, e.g., to enable packet information comparison for purpose of retransmission detection. An amount of packet information that is stored can be limited to a certain number of senders to control the impact of packet information storage on memory resources. | 05-08-2014 |
20140133407 | CONNECTION INFORMATION FOR INTER-DEVICE WIRELESS DATA COMMUNICATION - Techniques for connection information for inter-device wireless data communication are described. In at least some embodiments, a broker device maintains wireless connection information for various wireless devices. The wireless connection information includes wireless channels at which particular wireless devices can be accessed. The broker device can provide the wireless connection information to various other devices to enable wireless communication with the wireless devices. | 05-15-2014 |
