OGAS: Omni-directional Glider Assisted Scheme for autonomous deployment of sensor nodes in open area wireless sensor...

Area of Science:

• Robotics and Autonomous Systems
• Environmental Monitoring
• Wireless Communication Networks

Background:

• Wireless Sensor Networks (WSNs) are crucial for monitoring hostile and unreachable environments.
• Optimal sensor node (SN) placement is vital for WSN efficiency.
• Deploying SNs in large-scale regions presents significant challenges.

Purpose of the Study:

• To propose an autonomous air-borne scheme for precise SN placement in large-scale regions.
• To address the challenges of SN deployment in difficult terrains and environments.
• To improve the accuracy and efficiency of SN deployment models.

Main Methods:

• Utilizing an Omni-directional Circular Glider (OCG) for each SN.
• Implementing a recursive path correction model for orientation control during flight.
• Aerial deployment of SNs, which then pilot OCGs to predetermined locations (PLs).

Main Results:

• The proposed OCG scheme enables SNs to update direction mid-flight with a zero turning radius.
• Simulation and hardware implementation confirm operational effectiveness in environmental winds.
• The model demonstrates superior time-efficiency and accuracy compared to existing SN deployment methods.

Conclusions:

• The autonomous air-borne scheme provides a precise and efficient solution for WSN deployment in challenging large-scale areas.
• The OCG and recursive path correction model are robust against environmental factors like wind.
• This approach significantly enhances the state-of-the-art in sensor node deployment technology.
