Time Delay Complex Chen Chaotic System and Secure Communication Scheme for Wireless Body Area Networks

Abstract

Although many chaotic systems with time delays have been studied in recent years, most studies have only focused on the theoretical level, without special applications. Therefore, we present a basic introduction of a time delay complex Chen chaotic system, including the influence of parameter changes and time delay factors on the time delay system. On the basis of complex modified projection synchronization (CMPS), we detail the design of a new controller and communication scheme and apply this communication scheme to a wireless body area network (WBAN), in order to encrypt and decrypt body data collected by sensors. Finally, we perform a numerical simulation, demonstrating the effectiveness of the proposed communication scheme.

A comparative analysis on synchronization of two general class of chaotic systems using non-linear feedback control and feedback linearization techniques

“…Choosing [P , P , P ] = [27,27,27], we ensure that system (21) has its poles in LHS of the S-plane, hence the auxiliary system is proved to be stable, subsequently error dynamics will also be stable (converging) in nature.…”

“…Likewise, in [20], Nonlinear synchronization scheme is presented for the time delay chaotic systems which is also having channel noise, an integrator is used for suppressing the effect of channel noise. Using complex modified projection synchronisation (CMPS), a time delay complicated Chen chaotic system with parameter change and time delay factors is investigated in [21], and the strategy is implemented to a wireless body area network (WBAN) to encrypt and decode body data acquired by sensors.…”

Generalized Function Projective Synchronization of Two Different Chaotic Systems with Uncertain Parameters

“…Projective synchronization (PS) is more complex than CS but simpler than GS. Additionally, PS is useful in extending binary digital to M-nary digital communication to achieve faster communication [18][19][20].…”
