Enhanced Sensor node lifetime Based Routing Protocol in Mobile Wireless Sensor Networks

Abstract

Mobile Wireless Sensor Networks (MWSNs) are pivotal in facilitating real-time data collection and monitoring in dynamic environments. However, the Sensor nodes' low energy resources limit their lifespan. This study proposes an enhanced sensor node lifetime routing protocol (ESLRP) tailored specifically for MWSNs improve sensor node longevity while optimizing communication. ESLRP leverages a multi-faceted approach to prolong sensor node lifetime. Firstly, it integrates energy-aware routing algorithms that dynamically adapt to node energy levels and network topology changes. By intelligently selecting energy-efficient routes, ESLRP minimizes energy consumption during data transmission, thus prolonging sensor node life. Moreover, ESLRP incorporates mechanisms for energy harvesting and adaptive power management. Sensor nodes are equipped with energy harvesting modules, enabling them to harness ambient energy sources such as solar or kinetic energy to replenish their power reserves. Additionally, adaptive power management techniques are employed to adjust node power levels based on communication requirements, further optimizing energy utilization and enhancing overall network resilience. Furthermore, ESLRP integrates data aggregation and compression to reduce network congestion and duplicated data transfer. By aggregating and compressing data at intermediate nodes, ESLRP minimizes the energy expended on data forwarding, prolonging sensor node lifetime while maintaining data fidelity. To evaluate the efficacy of ESLRP, comprehensive simulations are conducted under various mobility scenarios and network conditions. Results demonstrate that ESLRP outperforms current routing methods for sensor node lifetime extension, energy efficiency, and network resilience.
