    Abstract: A method of facilitating communication in a wireless ad-hoc network comprises: generating, at a node in the wireless ad-hoc network, target availability information with regard to one or more transmission slots, the target availability information indicating whether the node is permitted to receive a transmission during each transmission slot; generating, at the node, owner availability information with regard to one or more transmission slots, the owner availability information indicating whether the node is permitted to transmit during each transmission slot; and broadcasting, from the node, the target availability information and the owner availability information to separately indicate availability as either an owner or a target for one or more transmission slots.

    Abstract: Low-power transmitter and/or receiver devices are provided by sacrificing time and/or frequency diversity in exchange for lower power consumption. When channel conditions indicate that time and/or frequency spreading are unnecessary for transmissions, a transmitter may enter into a power-conservation mode in which transmissions are performed using a time gating scheme or a time repetition scheme. In the time gating scheme, symbols are transmitting just once, rather than a plurality of times, but with increased transmission power. In the time repetition scheme, copies of the same symbol are transmitted a plurality of times on the same frequency on different symbol transmission periods, instead of being retransmitted on different frequencies on different symbol transmission periods. Consequently, the symbol can be generated once and stored for subsequent retransmission, thereby allowing some of the transmitter/receiver chain components can be operated at a lower duty cycle or processing speed to conserve power.

    Abstract: An exemplary method for reserving medium access in an ad hoc network comprises transmitting a reservation request by a reservation owner, the reservation request identifying a reservation allocation, a reservation target, and a reservation type. The reservation type identifies exclusive use of the reservation allocation by the reservation owner and the reservation target during a reservation period. The reservation target may employ a prioritized contention access (PCA) scheme to access the reservation allocation. Alternatively, an idle portion of the reservation allocation may be subdivided into a plurality of slots including even slots and odd slots, and the reservation owner gains access to the idle portion by starting to transmit during an even slot, while the reservation target gains access to the idle portion by starting to transmit during an odd slot. In yet another embodiment, the reservation owner transmits an outgoing clear to send (CTS) communication to the reservation target to transfer ownership of the reservation allocation to the reservation target, and receives an incoming clear to send (CTS) communication from the reservation target to regain ownership of the reservation allocation.

    Abstract: In general, techniques are described for encoding static video data using a baseline video encoder. A device comprising a baseline video encoder, a wireless interface and a control unit may implement the techniques. The baseline video encoder encodes a portion of this static video data at a first quality. The wireless interface wirelessly transmits the encoded first portion to a remote display device. The control unit identifies a region of interest in the portion of the video data to be re-encoded at a second quality, where the second quality is higher than the first quality. The baseline video encoder re-encodes the identified region of interest at the second quality without re-encoding any other regions of the portion of the video data at the second quality. The wireless interface wirelessly transmits the re-encoded identified region of interest to the remote display device.

    Abstract: Systems and methods for avoiding conflict in a wireless mobile display digital interface (WMDDI) environment including both host and client devices. In one aspect, the presently claimed invention includes a system and/or method that is configured for broadcasting a first multicast MAC address by a first host to at least one first client in a predetermined geographic area and broadcasting the first multicast MAC address by a second host to at least one second client in the predetermined geographic area. The system and/or method can be further configured for determining a priority between the first host and the second host when the second host receives multicast packets transmitted by the first host and changing to a second multicast MAC address by a least priority host of the first host and the second host.
