Chaotic Frequency Hopping Control in the Communication of Multi-hop Wireless Network

摘要

Based on the cross feedback control scheme of the variables, this paper presents a novel two-dimensional logistic map which shows excellent randomicity. The Pseudo-noise (PN) sequence obtained from this chaotic map is used to control multiple frequency synthesizers to hop on the entire bandwidth spectrum randomly. This strategy is applied to Frequency Hopping (FH) communication of multi-hop wireless network in order to improve anti-jamming and anti-interception abilities of the system. Simulation results show that the whole process for sending and receiving information in multi-hop communication has been achieved and the information signal has been restored well at the receiver. The main contributions of this paper are the constructing way of the two-dimensional chaotic map with enhanced randomness and the expansion of the application area to multi-hop wireless network.
