The present invention may apply a dynamic spectrum awareness algorithm to facilitate effective utilization of the available communications spectrum in an environment of the mobile ad hoc network, support both delay-sensitive and delay-tolerant traffic types on the mobile ad hoc network, and provide a defined quality of communications service for both the delay-sensitive and the delay-tolerant traffic.

Abstract: In embodiments of the present invention improved capabilities are described for a mobile broadband routable internet (MBRI) providing for carrier-grade, networked, broadband, IP-routable communication among a plurality of mobile devices, where the mobile devices may represent a plurality of nodes that are linked together through a mobile ad-hoc network (MANET). Mobile devices may operate as peers in a peer-to-peer network, with full IP routing capabilities enabled within each mobile device, thereby allowing routing of IP-based traffic, including deployment of applications, to the mobile device without need for infrastructure conventionally required for mobile ad hoc networks, such as cellular telephony infrastructure. Full IP-routing to mobile devices may allow seamless integration to the fixed Internet, such as through fixed or mobile access points, such as for backhaul purposes.

Abstract: Establishing communications between a plurality of nodes includes determining a set of frequencies to search for neighbor nodes, and performing an adaptive control channel initialization operation to detect zero or more neighbor nodes. If one or neighbor nodes are detected, an adaptive control channel with one or more of the one or more detected neighbor nodes is established.

Abstract: Adjusting parameters of a waveform includes facilitating wireless communication between a transmitting node and receiving nodes, where the transmitting node communicates with a receiving node over a channel. Spectrum conditions are estimated, where a spectrum condition describes spectrum utilization in the vicinity of surrounding nodes. Channel conditions are estimated, where a channel condition describes a channel of the plurality of channels. Waveform parameters are adjusted in response to the spectrum conditions and the channel conditions.

Abstract: Communicating between a plurality of nodes includes scanning a set of frequencies to determine spectrum awareness data for one or more frequencies; determining a maximum transmit power for one or more of the frequencies based at least in part on the spectrum awareness data for the frequencies; determining one or more channels, each channel occupying at least a portion of the set of frequencies; and selecting one or more of the one or more channels as a bearer.

Abstract: Scheduling communication between a first node and one or more neighbor nodes includes, at each of the first node and the one or more neighbor nodes determining a neighborhood of the one or more neighbor nodes; classifying each of the first node and one or more of the neighbor nodes as one of a transmitting node or a receiving node for a time slot; and determining one or more links, wherein each link is defined by a pair of nodes and an associated bearer frequency, and wherein at least two of the links have different associated bearer frequencies; and scheduling one or more links for the time slot.

Abstract: Using bearer channels for wireless nodes includes initiating communication among the wireless nodes that include a node and one or more neighbor nodes. An adaptive channel operable to communicate messages between the node and the neighbor nodes is established. One or more bearer channels are selected. The one or more neighbor nodes are notified of the one or more selected bearer channels using the adaptive channel. The node and the neighbor nodes communicate over the bearer channels.

Abstract: Communicating between a plurality of nodes includes sensing spectrum activity on at least one channel; generating spectrum awareness data based at least in part on the sensed spectrum activity; determining at least one selected bearer based on the spectrum awareness data; negotiating among nodes to select at least one bearer based on various spectral use criteria.

Abstract: Communicating between a plurality of nodes includes: at one or more of the plurality of nodes, sensing spectrum activity on at least one channel; creating and maintaining at least one spectrum awareness table based at least in part on the sensed spectrum activity, determining at least one selected bearer based on the at least one spectrum awareness table; performing an adaptive control channel initialization operation to detect zero or more neighbor nodes.

Abstract: In one embodiment, a method for generating an adaptive air interface waveform includes generating a waveform that includes a variable carrier frequency and variable bandwidth signal. The variable bandwidth signal includes one or more subcarriers that are dynamically placeable over a range of frequencies, and each subcarrier is separately modulated according to a direct sequence (DS) spread spectrum (SS) technique. The waveform has an embedded pilot usable to optimize one or more spectrum efficiencies of the waveform. A modulation constellation, a code rate, and a code length of the generated waveform are adapted according to an available spectrum and one or more sub-carrier conditions.
