Wireless sensor networks have extensively been used for placing the nodes in a linear topology, constituting a special class of networks called linear sensor networks. In a densely deployed linear network case, issues related to optimal resource allocation and networking may persist because the standard sensor network protocols attempt to manage the network as a mesh or ad hoc infrastructure. Pipeline transportation of fluid is controlled by many laws to avoid failure and therefore serious disasters. This paper presents a cost optimum solution to small leaks in pipelines through the use of an array of piezoelectric film sensors embedded in a mobile robot. From time to time, the new robot is passed through the pipeline to detect small leakage precisely before detrimental corrosion and then major failure occurs. This paper presents a cost optimum solution to small leaks in pipelines through the use of an array of piezoelectric film sensors embedded in a mobile robot. It’s common in the industry to use an automatic system, which is installed at all joints along the pipeline, to detect a large leak and send its location wirelessly to the main controller. Main aim of this project is to improve efficiency of the system and provide additional features.
