Evaluation of Energy-Efficient Cooperative Scheme for Wireless Sensor Nodes Used in Long Distance Water Pipeline Monitoring Systems

Due to the significant demand of energy efficient wireless sensor network (WSN) for different industrial applications, it is important to research and develop robust energy efficient schemes for WSN nodes. One such application is monitoring leakage, bursts and other anomalies in long distance water pipeline systems. In this paper, we propose an energy-efficient cooperative scheme for a group of mobile wireless sensor nodes deployed inside the pipeline. The nodes are supposed to run cooperatively in order to save their resources. It is assumed that only one node shall remain active for a specific period of time while all other nodes are in sleep mode. As soon as the active node completes its cycle, it goes to sleep while another node is triggered by its timer to wake up and continue the process. The proposed scheme is evaluated for energy consumption by respective nodes with the help of a mathematical model.
