Performance of the application of chaotic signals in IEEE 802.11b and wireless sensor networks

Abstract

Chaos engineering for wireless communications is an emerging field of research. There are certain advantages that chaotic dynamics could offer to conventional wireless access systems such as increased security and encryption, low-power communication, and hardware simplicity. This paper describes how chaotic spreading could be used in broadband wireless access systems such as IEEE 802.11b by replacing the spreading sequences with chaotic ones and thus improving the performance under narrowband sinusoidal jammer and Bluetooth interference. The results are being presented with the use of link level simulations. It also describes how quadrature chaos shift keying (QCSK) could be used for wireless sensor networks (WSNs) as the simplicity of hardware when using chaos in communication protocols could successfully lead to cubic millimeter scale sensor nodes and presents the performance of QCSK under narrowband sinusoidal jammer with the use of mathematical models
