Publish paper without consulting project guide?
I'll assume "guide" means "supervisor." Hence, your project supervisors are insisting that they be listed as co-authors on your SDN paper written under their supervision. Assuming that their supervision resulted to an intellectual contribution to the paper, I believe you have an obligation to list them as co-authors. On the other hand, if your supervisors provided no input / no guidance, then I think you can publish without listing them as co-authors. You could invite the department head to mediate, if there is a dispute over whether the supervisors contributed.
