Tuning chaos in network sharing common nonlinearity

•Networks sharing common nonlinearity akin to star network topology is investigated•Modeling of common nonlinear element for the chaotification of desired number of nodes in the network is presented.•Networks comprise both autonomous and forced oscillators are considered.•The dynamics of these networks has been studied via numerical, analytical, experimental and Multisim simulations techniques.

In this paper, a novel type of network called network sharing common nonlinearity comprising both autonomous and non-autonomous oscillators have been investigated. We propose that these networks are robust for operating at desired modes i.e., chaotic or periodic by altering the v–i characteristics of common nonlinear element alone. The dynamics of these networks were examined through numerical, analytical, experimental and Multisim simulations.
