Abstract :
The focus of this paper is on the performance of an adaptive transmission protocol for frequency-hop (FH) radio networks in which the radios can adjust the power in the transmitted signal and the rate of a Reed-Solomon code to respond to variations in partial-band interference and propagation loss. The adaptation is based on side information from the FH receiver and on information derived from the decoder. The results presented in this paper are obtained from a simulation of a wireless FH radio network in which the characteristics of the links are time-varying. These results demonstrate that the adaptive transmission protocol can improve the quality of a link by adapting to variations in both path-loss and interference to take advantage of favorable channel conditions
