Wireless sensor networks (WSN) consist of sensor nodes. These sensor nodes have the ability of sensing variety of environment. WSN are very small in size and have limited processing capability and very low battery power. So most of the research is based on to reduce power consumption.

Wireless Sensor Network (WSN) has gained worldwide attention in recent years. The design of a WSN depends significantly on the application. In sensor network design, physical and logical topology plays a major role. Transfer information in real time means, to provide a required result in a bounded time. Large-scale sensor networks will not be able to simply send all the raw sensed sample data to a sink. This paper presents an approach of simulation of various sampling techniques (logical topology) of industrial stacks emission and also defines a network with rough node deployment. The simulation of the sampling techniques is carried out using Castalia simulator based on OMNET++ language.
