Ensembles of dynamic systems in active wireless networks

Abstract

Generalized wireless sensor network (active sensor networks) are considered as a multicomponent processor platform whereby the behavior of interacting dynamic systems is simulated. During the simulation process, each node of the sensor network is represented as a dynamic system. The equations of the system are solved using a specialized computing device (microcontroller) located in each network node. The interaction between dynamic systems is performed so that system state data are transmitted over radio channels between active network nodes. The simulation scheme is investigated by the example of an ensemble of coupled logistic maps. This ensemble is experimentally implemented in the network comprising PPS-43 direct chaotic transceivers equipped with actuator boards, which include microcontroller to iterate maps and a display unit to visualize information (colored light-emitting diode). The simulation technique is described, experimental results are presented, and their analysis is accomplished.
