Researchers have developed a cutting-edge IoT framework called REEFSM (Reliable and Energy-Efficient Framework with Sink Mobility) that optimizes energy efficiency and data reliability in underwater acoustic sensor networks. This innovative approach utilizes strategically placed mobile sink nodes to reduce the need for intermediary relay nodes, leading to a 43% reduction in energy consumption and a 35% increase in data reliability compared to existing protocols. The framework ensures zero dead nodes, minimal packet loss, and high data accuracy, paving the way for more sustainable and reliable data collection in underwater environments. This research holds great promise for advancements in the field of Internet of Things (IoT) and underwater sensor networks.
Underwater Sensor Networks: Challenges and the REEFSM Solution
Underwater sensor networks play a crucial role in various applications, such as environmental monitoring, oceanographic research, and offshore enterprises. However, these networks face significant challenges in optimizing energy efficiency and data reliability due to the constrained battery capacity of sensor nodes and the unique characteristics of the underwater environment.
To address these issues, the researchers developed the REEFSM framework, which leverages mobile sink nodes strategically placed within the network. By reducing the reliance on intermediate relay nodes, REEFSM achieves a remarkable 43% reduction in energy consumption and a 35% increase in data reliability compared to existing protocols like EERBCR and DEADS.
A Versatile and Reliable Network Architecture
The REEFSM framework employs a two-dimensional network model, with the area divided into four regions, each further segmented into three sections. Four mobile sink nodes are positioned centrally within these zones, ensuring minimal transmission distances and reducing the need for intermediary nodes.
Key features of the REEFSM framework include:
– Direct communication between sensor nodes and mobile sinks, bypassing the need for energy-hungry relay nodes
– Optimized wake-up and sleep cycles for sensor nodes, minimizing energy consumption
– Structured network architecture with balanced coverage and reduced latency
– Efficient neighbor discovery and packet forwarding algorithms for reliable data transmission
Exceptional Performance and Energy Efficiency
The simulation results demonstrate the superior performance of the REEFSM framework. Compared to other protocols, REEFSM shows a significant reduction in energy consumption, with the network maintaining 536 joules of residual energy at the end of 1000 simulation rounds, while other protocols like DBR and EEDBR deplete their energy completely.
In terms of data transmission, REEFSM exhibits the highest number of packets sent to the sink nodes, reaching 64,235 by the end of the simulation. Crucially, it also displays the lowest packet drop rate, with only 5,888 drops, highlighting its exceptional reliability and efficiency in data delivery.
