An Asynchronous Dual Radio Opportunistic Beacon Network Protocol for Wildlife Monitoring System

In this paper, we introduce an asynchronous dual interface opportunistic beacon network for wildlife monitoring. Unlike conventional opportunistic networks which are based on multi-copy data replication techniques, our approach utilizes an optimized single-copy beacon data transmission to achieve high energy efficiency. Furthermore, the collected data is aggregated and relayed to the central system by leveraging a low power and long range radio to provide high connectivity coverage. This approach will allow ultra-low power IoT devices to be deployed for sustainable wildlife monitoring applications. We evaluate the proposed approach in an actual animal movement use-case scenario. The results indicate that the proposed approach outperforms the traditional opportunistic network protocols in- terms of energy consumption and packet delivery ratio.
