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.
