Charging Protocol for Partially Rechargeable Mobile Sensor Networks.

Area of Science:

• Computer Science
• Electrical Engineering
• Networking

Background:

• Wireless sensor networks (WSNs) are vital for daily services but face critical energy limitations.
• Existing solutions for wireless rechargeable sensor networks (WRSNs) include static charging or mobile chargers, which are less effective in partially rechargeable environments.
• Extending WSN lifetime and improving recharge efficiency in such scenarios remain significant challenges.

Purpose of the Study:

• To propose a novel flexible charging protocol for mobile sensor networks (MSNs) enabling energy transmission between regions.
• To address the challenges of energy sharing and efficiency in partially rechargeable WSN environments.
• To enhance the operational lifetime of wireless rechargeable sensor networks.

Main Methods:

• Developed a flexible charging protocol for MSNs to facilitate energy transfer from supply regions to other areas.
• Deployed mobile rechargeable sensors for environmental monitoring and energy replenishment.
• Sensors within the energy supply region move to recharge and transmit energy to sensors outside this region.

Main Results:

• The proposed flexible charging protocol demonstrates improved efficiency compared to existing methods in various scenarios.
• Evaluation results indicate enhanced energy sharing capabilities within the mobile sensor network.
• The protocol effectively extends the operational lifetime of the WSN in partially rechargeable settings.

Conclusions:

• The flexible charging protocol offers a more efficient solution for energy management in WSNs, particularly in partially rechargeable environments.
• This approach effectively tackles the energy supply limitations of WSNs by enabling dynamic energy sharing.
• The study highlights the potential of mobile sensor networks and flexible charging strategies for future wireless network applications.
