Lifetime ratio improvement in relay nodes using CWSN for cooperative wireless sensor networks

Abstract

The frequent interchange of information between nodes is made possible by a lifetime extension of battery-operated devices, which is a crucial design consideration. A broad framework for the performance trade-off between packet error rate (PER) and network lifespan in Wireless sensor networks (WSN) and collaborative wireless network sensors (CWSN) is provided in this research. According to the simulation results, when there are more sensors added, the PER for WSNs lowers. Additionally, it has been shown that choosing the sensors with the longest lifespan is no longer the best course of action for reducing PER. As the number of sensors surpasses a specific threshold, it is demonstrated that the drop in the PER is not proportional to the growth in the network lifespan. The lifetime performance of CWSN also grows with the number of sensors, and its PER falls with the number of sensors.
