摘要： The present invention is a method and system for propagating routing information in a wireless network. In an exemplary embodiment, the method includes defining a set of artery nodes to propagate distance vector routing information throughout the wireless network. The set of artery nodes may broadcast distance vector routing information to neighboring network nodes. The method may also include receiving distance vector routing information by the neighboring nodes to modify distance vector routing tables defined within each of the neighboring nodes. The set of artery nodes may then re-broadcast distance vector routing information in order to propagate distance vector routing information throughout the wireless network.

摘要： An improved protocol for MANETs used in TDRS, JTRS systems and the like, where multiple channels have multiple communication links operating simultaneously within range of each other. All nodes in such MANETs are able to communicate with all their “1 hop” neighbors, even if the neighbors are on different channels. An improved inter-channel communication protocol using a bridge node allows nodes on separate channels to communicate. The bridge node operates as a pseudo-bi-directional link between two neighboring channels in the MANET. An Inter-Channel Bridge Node Communication Protocol determines contention free time slots on both channels, and then reserves one time slot to be used for inter-channel communications. The reserved time slot usage is then divided between the transmitted bridge node and the receiving node in the neighboring channel.

摘要： A node for connecting to an interconnection network may include a network interface. The node may also include a processor coupled with the network interface. The node may further include a memory coupled with the processor. The processor may be configured for periodically analyzing the connectedness of the node to the interconnection network to determine a metric for the node in relation to other nodes within the interconnection network. The node may be designated as a member of a core set of nodes within the interconnection network based upon the metric. The node may detect at least one of a derived update or an update indicating another node connects to or disconnects from the interconnection network. The node may transmit a routing update to another member of the core set of nodes only when the node is designated as part of the core set of nodes.

摘要： A method for handling data transmission errors in a wireless communication network includes receiving a first data from a first node at a second node using a data transmission protocol having a first slot for transmitting the first data. The first slot includes a plurality of bits and a first slot header comprising an acknowledgment request for at least one group of bits. The method also includes evaluating the first set of data for errors and generating a second slot using the data transmission protocol. The second slot includes at least a second slot header comprising acknowledgement data in response to the acknowledgement request. The acknowledgement data has a structure based on a Forward Error Correction (FEC) protocol block size. The second slot is then transmitted to the first node.

摘要： An apparatus and method for providing external bump-in-the-wire cryptographic capability to a legacy radio (which may or may not include embedded cryptography) includes an appliqué couplable to the legacy radio and to an intercom, handset, or other user device. The appliqué extracts and stores in memory radio status information from the legacy radio (channel information, cryptographic instructions, alarm conditions) by intercepting control signals, polling the legacy radio, or listening in on channels used by the legacy radio. If TSVCIS 2.1 or CMI-compatible encryption is required, the appliqué may encrypt or decrypt a message with the appropriate cryptographic keys based on the extracted radio status information. The appliqué may include a bump-in-the-wire device or a bump-in-the-connector device directly couplable to an intercom port of a vehicular mounted SINCGARS legacy radio.

摘要： An architecture for a frequency hopped spread-spectrum transmitter-receiver in an advanced tactical data link packet switched network that ensures optimal Statistical Priority-based Media Access (SPMA) performance, enables more efficient packing of hop channels in a given allocated bandwidth and counteracts hostile jamming. The transmitter-receiver supports a scalable symbol rate mode that reduces the symbol rate in the time domain and decreases the bandwidth in the frequency domain, over a predetermined prior value. A transceiver according to the present architecture is able to statically or dynamically scale the symbol rate of transmissions, operate in burst mode and change the hop set. In one embodiment the transceiver is part of a Software Defined Radio (SDR).

摘要： An interference cancellation system supports a dynamic operating range from maximum interfering signal level to the on-channel noise floor. The system uses a novel combination of analog and digital processing effectively cancelling 1) high-level interfering signal components, 2) low-level interfering noise, and 3) distortion components. The system employs an interrelated combination of cross-domain analog and digital processing techniques to defeat the inherent dynamic range limitations existing in either individual domain.
