Energy Efficient Data Collection Using Predefined Path Constrained Mobility for Mobile Sinks in Wireless Sensor Networks
Mohammed F. Suleiman, Usman Adeel · 2023
Recently, the utilization of mobile sinks (MSs) has gained significant attention in wireless sensor networks (WSNs) research due to its potential for improving network lifetime compared to traditional static sinks. However, mobility in WSNs still presents challenges such as node failures in random mobility techniques and high computational and processing resources required in predicted mobility approaches, which can impact long-term stability and network lifetime. In this study, we propose a Predefined Path Constrained Mobility (PPCM) routing protocol utilizing multiple sinks stationed at different areas of the network. These sinks move in a fixed pattern to collect data from sensor nodes. Through evaluation, we demonstrate that the PPCM protocol outperforms existing routing protocols such as Random Multiple Mobile Sink (RMMS) and Multiple Random Mobile Sink Confined (MRMS-C) protocols in terms of overall network lifetime. The proposed protocol offers a potential solution to address routing challenges in WSNs with the use of mobile sinks.
