| 20100103883 | DISTRIBUTED RESERVATION PROTOCOL ENHANCEMENT FOR BIDIRECTIONAL DATA TRANSFER - A method for reserving bandwidth in a wireless system is provided. The method includes reserving one or more communications slots between two or more wireless devices communicating in a wireless network and providing preferential access to at least one wireless device across the network according to a first subset of the communications slots. The method also includes providing preferential access to at least one other device across the network during a second subset of the communications slots. | 04-29-2010 |
| 20100162070 | METHOD AND APPARATUS FOR OPTIMIZING A RETRY LIMIT FOR MULTIMEDIA SYSTEMS THAT ARE PRONE TO ERRORS - Devices, systems and methods for optimizing a number of retransmission attempts in a multimedia environment and managing delays in a host MAC layer. In its various aspects, the presently claimed invention includes several methodologies and systems that are configured for determining an optimal retry limit in response to one or both of a packet error rate bound and a latency bound. To the extent that the retry limit is determined with respect to one of the aforementioned boundaries, the presently claimed invention may include determining a confidence level that the non-selected bound will also be met by the selected retry limit. The presently claimed invention details devices, systems and methods optimizing the number of retransmission attempts to ensure delivery of the selected data packets while guarding against undue delays and application disruptions. | 06-24-2010 |
| 20100202453 | ASSOCIATION PROCEDURE TO ENABLE MULTIPLE MULTICAST STREAMS - A method, system and computer program product for a wireless mobile display digital interface (WMDDI) association procedure that allows establishing and joining more than one multicast group to facilitate the interoperability of multiple client devices based on host and client capabilities. The protocol provides for the exchange and update of capabilities and multicast addresses for layered multicast transmission applications. The system is used for interoperating devices with different capabilities and provides for efficient transmissions by using different multicast addresses mapped to different layers of a bitstream. The protocol adapts to changes in capabilities, in joining/releasing of multicast addresses and in link quality. | 08-12-2010 |

| 20110013572 | SYSTEMS AND METHODS FOR RESOURCE ALLOCATION SERVING COMMUNICATION REQUIREMENTS AND FAIRNESS - A demand aware fair resource allocation technique is operable to allocate communication resources in multi-hop networks under the joint consideration of communication requirements and fairness. Embodiments operate to provide allocation of time slot resources in TDMA based multi-hop wireless networks under the joint consideration of QoS and fairness. Embodiments operate with respect to information regarding maximal common slot set flow contention. An iterative process is applied with respect to the information regarding maximal common slot set flow contention to allocate communication resources providing a balance between meeting communication requirements and fairness. According to embodiments, an inter-graph process iteratively selects a maximal common slot set for which resource allocation with respect to various flows is to be performed and an intra-graph process assigns communication resources in the maximal common slot set providing a balancing between meeting communication requirements (e.g., QoS) and providing fairness. | 01-20-2011 |
| 20110013644 | SYSTEMS AND METHODS FOR PROVIDING RESOURCE ALLOCATION MEETING COMMUNICATION CONSTRAINTS FOR MULTI-HOP NETWORK DATA FLOWS - Systems and methods identify a multi-hop network data path with sufficient available resources at each node along the data path to facilitate desired end-to-end data flow. Embodiments operate to identify resource constraints for meeting QoS or other communication requirements at each node of a multi-hop data path and propagate the resource constraint information within the network for use in identifying data paths suitable for supporting a desired end-to-end data flow. A resource allocation algorithm operable to allocate resources to achieve an end-to-end data flow meeting the communication requirements is implemented according to embodiments. A resource allocation algorithm of embodiments operates to ensure efficient use of the available resources so that desired conditions are satisfied when the resource requirements are met at each intermediate node for the upstream and downstream links and also both links simultaneously. | 01-20-2011 |
