ADAPTIVE FORWARDING IN FREQUENCY-HOP SPREAD-SPECTRUM PACKET RADIO NETWORKS WITH PARTIAL-BAND JAMMING

This paper is concerned with adaptive protocols for forwarding around localized partial-band jamming in a frequency-hop (FH) packet radio network. These protocols specify the ways in which a radio is permitted to modify its normal forwarding procedures based on information obtained locally in the network. A computer program has been developed to simulate an FH packet radio network with partial-band jamming and interference due to other FH and narrowband radios. The radios in the network use time-slotted, receiver-directed, FH spread-spectrum signaling. Results on throughput, delay, and end-to-end probability of success are presented, and comparisons between different forwarding protocols are obtained for a static network topology with both static and mobile network jamming.
