Abstract: Wireless Sensor Networks (WSNs) have been gaining growing interest in the past years; WSN tasks of a each sensor network work include not only monitoring and measuring certain phenomena, but also delivering gathered data. Sensor network require applying different techniques used in wired and wireless network. Simulation tools for wireless sensor networks are increasingly being used to study sensor webs and to test new applications and protocols in this evolving research field. It is useful to researcher to verify new ideas and analyze with proposed algorithms in virtual environment and help to avoid expensive hardware usage and time consumption also. This paper provides a comprehensive survey and comparisons of various popular sensor network simulators with a view to help researchers to choose the best simulator available for a particular application environment.
