Use of Side Information in Adaptive Protocols for Spread-Spectrum Packet RadioNetworks

摘要

A summary of the results obtained in research sponsored by the Army ResearchOffice 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.
