Available in PDF, EPUB and Kindle. Book excerpt: A summary of the results obtained in research sponsored by the Army Research Office under contract DAALO3-92-c-0018 and conducted during the period July 1, 1992 to August 31, 1995 is presented. Reliable data distribution within spread spectrum packet radio networks requires high performance from the network protocols. The high variability of the qualities of the links and the unique characteristics of frequency hop spread spectrum signaling impose special requirements for network protocols that are to be employed in frequency hop packet radio networks. Side information that can be extracted from the received spread spectrum signals that are embedded in noise and interference provides information about the quality of the links in the packet radio network. This research investigated several techniques for utilizing side information to aid the network protocols in establishing reliable routes in a mobile, tactical packet radio network.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes research in adaptive protocols for spread- spectrum packet radio networks. Adaptive forwarding and routing protocols were developed and their performance was determined by simulation of a frequency-hop packet radio network with mobile partial-band jamming. New forwarding protocols were designed to permit short-term adaptation to changes in the interference environment in the network. A new routing technique, called least-resistance routing was developed, and various versions of this routing method were examined. Comparisons were made between different versions of least-resistance routing and between least-resistance routing and previously developed adaptive routing techniques. It was found that least-resistance routing is an effective way for dealing with mobile jamming in a frequency-hop packet radio network. Significant increases in throughput and end-to-end probability of success were obtained by use of least-resistance routing.

Available in PDF, EPUB and Kindle. Book excerpt: Results are reported on research in adaptive transmission for mobile wireless frequency-hop communication networks. Adaptive protocols were devised and performance results were obtained tor frequency-hop transmission with Reed-Solomon coding and frequency-hop transmission with turbo coding. A method for generating side information from interleaving was developed, and the performance of Hermitian codes was evaluated. Adaptive transmission protocols were integrated with adaptive routing protocols to provide energy efficiency in mobile, tactical, frequency-hop, wireless ad hoc networks.

Available in PDF, EPUB and Kindle. Book excerpt: This research project has focused on the development of protocols and reception techniques for distributed packet radio networks that exploit directional antennas to provide high-throughput, reliable data and voice communications, and that conserve sensor battery energy when relaying sensor data through the network. The research focused on the development of channel-access protocols, adaptive link protocols, and adaptive routing protocols for packet radio networks that employ spread-spectrum modulation. One goal of the research has been to ensure that critical data is forwarded from microsensors to data-fusion centers or mobile-radio end systems while efficiently utilizing the limited energy in the sensors' nonrechargeable batteries. A primary research emphasis has been the design of protocols that minimize the total energy consumption for store-and-forward routing through the sub-network of microsensors, and that account for energy depletion in individual sensors. An important component of this emphasis is the design of protocols that utilize more capable radio systems in the tactical network whenever possible to minimize the amount of data relaying required of the sensors. A second, related emphasis has been efficient exploitation of the presence within the tactical network of mobile radio systems that utilize directional antennas. Primary topics of the research include the design of the packet-acquisition techniques, channel-access protocols, and resource-management techniques that allow a node with multiple fixed-beam directional antennas to exploit their capabilities without introducing a significant increase in the complexity of the network's protocols. A list of related publications is included.
