Introduction: From the past few years wireless sensor networks (WSN’s) have gained global attention. It is a promising technology that has been extensively used in various critical and long-lasting applications. A Wireless Sensor Network (WSN) has a large number of energy constrained sensor nodes that have the capability to compute and communicate. They are used to identify the events of interests and transfer the data to the sink node. WSN is categorized into fixed WSN and mobile WSN. Target area has fixed sensors for performing their roles in fixed WSN’s while there are moving sensors to perform sensing in the mobile WSN’s. The cost of building and maintenance depends on the sensor networks size, whether small-scale or large scale networks, it only adds up to the total cost. Therefore, there is a necessity to detect and deal with sensor node faults and prediction in the energy consumption of sensors in the sensor networks. For constructing a WSN environment, appropriate protocols are required for the communication between the numbers of sensors. Large-scale sensor nodes are required for the placement of sensor nodes along with the placement algorithms. In this competitive environment because of rapidly increasing demands companies have to meet the terms of environmental regulations, increase the efficiency of their processes and meet with the corporate financial goals. For improving the productivity and efficiency of dynamic industrial manufacturing market, intelligent
