BF² VHDR based dynamic routing with hydrodynamics for QoS development in WSN

Area of Science:

• Computer Science
• Network Engineering
• Wireless Communication

Background:

• Hydrodynamic routing characteristics are crucial for Wireless Sensor Networks (WSNs).
• Existing flow and friction-based routing methods offer sustainability but neglect Quality of Service (QoS) improvements.
• The Flow-Flow-Friction-Velocity Based Hydro Dynamic Routing (F²VHDR) method fails to account for packet backflow, impacting service performance.

Purpose of the Study:

• To enhance the performance of existing hydrodynamic routing algorithms in WSNs.
• To address the limitations of F²VHDR by incorporating backflow monitoring.
• To introduce the Back Flow - Flow - Friction - Velocity Based Hydro Dynamic Routing (BF²VHDR) algorithm.

Main Methods:

• The BF²VHDR algorithm monitors bidirectional route flow, including backflow, to detect route failures and high traffic conditions.
• It computes backward and forward hydrology routing weights based on backflow, general route flow, traffic friction, and velocity.
• A route support weight is calculated using these hydrology weights for effective route selection.

Main Results:

• The proposed BF²VHDR algorithm demonstrates improved network throughput.
• The implementation of BF²VHDR leads to an increased lifetime of sensor nodes.
• BF²VHDR effectively manages packet backflow, enhancing overall network performance.

Conclusions:

• BF²VHDR offers a significant improvement over previous hydrodynamic routing methods in WSNs.
• The algorithm's ability to monitor and utilize backflow information enhances network efficiency and node longevity.
• BF²VHDR presents a viable solution for optimizing routing performance and extending the operational life of WSNs.
