Encounter based energy sharing in wildlife communication systems

Area of Science:

• Wireless Communication
• Network Systems
• Animal Ecology

Background:

• Wildlife communication systems face challenges in energy management and network longevity.
• Opportunistic encounters between nodes present opportunities for energy transfer.
• Existing energy balancing techniques may not be optimized for dynamic wildlife networks.

Purpose of the Study:

• To develop and evaluate a novel energy-sharing scheme for wildlife communication networks.
• To balance energy distribution among nodes and minimize energy loss.
• To enhance the overall lifetime and performance of wildlife communication systems.

Main Methods:

• Proposed a novel encounter-based energy-sharing (EBES) scheme utilizing single and multi-hop transmissions.
• Simulated EBES within a wildlife communication network context, integrating with opportunistic routing protocols (EBR, Spray&Wait, Epidemic).
• Compared EBES performance against existing energy balancing techniques (EA-Epidemic, EERPFAnt, OE-OLSR).

Main Results:

• EBES application over opportunistic routing protocols resulted in a 35% increase in network lifetime.
• EBES demonstrated significant improvements in remaining energy compared to EA-Epidemic (31%), EERPFAnt (26%), and OE-OLSR (15%).
• The scheme effectively balances energy and minimizes losses based on node encounter rates and buffer sizes.

Conclusions:

• The proposed EBES scheme is effective in enhancing energy balance and prolonging the operational lifetime of wildlife communication systems.
• EBES offers a viable solution for energy management in opportunistic networks, particularly those involving mobile nodes like wildlife.
• Further research can explore adaptive EBES parameters for diverse environmental conditions and animal behaviors.
