    摘要: A method for switching from a multimedia broadcast multicast services (MBMS) download to a hypertext transfer protocol (HTTP)-based delivery of dynamic adaptive streaming over HTTP (DASH) formatted content in an interne protocol (IP) multimedia subsystem (IMS) network is disclosed. The method can include a service control function (SCF) module receiving a session initiation protocol (SIP) re-invitation from a mobile device while the mobile device is receiving a MBMS download in a content delivery session including DASH formatted content. The SCF module can send a SIP invitation to an HTTP/SIP adapter to select an HTTP server for an HTTP-based delivery. The SCF module can receive a SIP acknowledgement from the HTTP/SIP adapter indicating a selection of the HTTP server for the content delivery session. The SCF module can forward the SIP acknowledgement to the mobile device indicating a switch to the HTTP server for the content delivery session.

    摘要: Retransmission techniques are disclosed. These techniques may be used in networks employing contention-based access schemes, such as CSMA. For instance, a device may receive a corrupted packet from a transmitting device, and determine a cause of the corruption. When the determined cause of the corruption is an in-network packet collision, the device allows the transmitting device to send a retransmission of the packet in accordance with a contention-based access scheme. However, when the determined cause of the corruption is other than an in-network packet collision, the device provides retransmission assistance to the transmitting device. This retransmission assistance may include a channel reservation for a retransmission, and/or one or more link adaptation suggestions for the transmitting device.

    摘要: Embodiments herein may operate at a cooperating relay station (CRS) in a wireless packet-carrying network (WPCN). A source-to-CRS (SC) link quality of an SC wireless channel may be estimated using signal quality information derived from a packet transmitted by a source station and received by the CRS. A CRS-to-destination (CD) link quality of a CD wireless channel may also be estimated using signal quality information derived from a packet transmitted by a destination station and received by the CRS. A source-to-destination (SD) link quality parameter representing SD link quality may be extracted by the CRS from the packet transmitted by the destination station. The CRS may decide whether to participate with the source station or with another CRS in transmitting an SD packet based upon the SC link quality, the CD link quality, the SD link quality, or a combination thereof. Other embodiments may be described and claimed.

    摘要: An ad-hoc network system for computing a proposed number of node-clusters that enable a relative threshold data rate. The ad-hoc network system includes a source terminal, a destination terminal, a plurality of relay terminals, and a cluster determination engine. The source terminal sends a network communication to a destination terminal via a plurality of relay terminals. The cluster determination engine computes a threshold data rate, C, for a number of hops, N, based on a transmission power constraint. The cluster determination engine determines a proposed route for the wireless communication from the source terminal to the destination terminal according to the threshold data rate, C.
