The modulational instability (MI) of dissipative ion-acoustic waves (DIAWs) in an electronegative plasma (ENP) consisting of non-Maxwellian electrons exhibiting the Tsallis distribution is investigated. By applying a reductive perturbation technique, we derive a modified nonlinear Schödinger equation for investigating the MI of the DIAWs. The criteria for the MI are derived and discussed briefly. It is observed that the plasma parameters significantly affect the growth rate and the bandwidth of the MI. Within the unstable region, it is shown that the MI of the wavepacket and the specific properties of various localized and periodic structures (Kuznetsov–Ma breather, Akhmediev breather, and Peregrine soliton) have significantly modified by including the collisional parameter. The ratio of electrons to positive ions and the index q of the nonextensive distribution for electrons are significantly modified the characteristics of the DIAWs. The relevance of this work can help some researchers in space and laboratory plasma, to explain the formation and development of dissipative breathers in ENPs.
