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: Network timing synchronization for an ad hoc network combines master node techniques and distributed timing techniques to provide highly accurate, low-overhead synchronization within different timing domains throughout the network.

Abstract: Methods and systems are disclosed herein for synchronizing network time in a mobile ad-hoc network (MANET). Each node in the MANET may be synchronized with all of its neighbors for effective communications. More specifically, a local timing reference may be adjusted according to measured errors in incoming control packets so that time slotted transmissions can be scheduled without collisions with other nodes. The method and system is a low overhead protocol that only requires a small amount of data attached to each scheduled transmission avoiding the requirement for separate messaging. This may reduce the overhead of maintaining the MANET providing additional efficiency and robustness.

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: 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: 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.
