Investigation of Adaptive Protocols for Spread-Spectrum Packet Radio Networks
Abstract
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.
