Abstract
The paper explores the use of opportunistic routing protocols in the context of remote sea emergency scenarios, using the MH370 plane crash as a case study. The study focuses on two opportunistic routing protocols, Epidemic and MaxProp, and evaluates their performance based on key metrics such as average latency and delivery probability.
The initial simulation suggests that with the current state of technology, it is unlikely that distress messages could be successfully delivered, as the communication range of the mobile nodes (debris) is insufficient to reach other ships or emergency services. To further explore the potential of these protocols, the study extends the simulation by adjusting the plane crash location to enable communication with the closest ship.
The extended simulations reveal that as the communication range increases, both protocols exhibit improved performance, with MaxProp consistently outperforming Epidemic in terms of delivery probability and average latency. The study also suggests the presence of an optimal communication range where the protocols utilize the network more effectively.
The paper discusses the advantages and limitations of the simulation model, highlighting the need for further enhancements, such as the incorporation of 3D space capabilities and more detailed maritime scenarios. Additionally, the study suggests the exploration of alternative communication technologies, such as long-range acoustic communication, as a potential game-changer in remote sea emergency scenarios.
Stats
The plane had gone missing from the radar around MYT 2:40am [8] 2014.
The debris scatter spanned 200 miles (320 kilometers) [11].
Ships ranging from general cargo ships and oil tankers to container ships and vehicle carrier, travel at average speeds between 9.25 – 14.95 knots ≈ 17 – 28km/h [13].
Coast guard ships have top speeds ranging from 28 to 45 knots [14].

"The absence of effective communication or distress signals during the critical period prompts an exploration into the viability of leveraging Opportunistic networks for emergency communication in remote areas."
"The simulation outcome strongly suggests that the technology and capabilities of modern communication networks are insufficient to facilitate the transmission of emergency information and whereabouts of the crash to emergency services or even other ships."
"Unless the mobile nodes can cover vast distances of hundreds of kilometres, or that there exists an extensive network of ocean moors spanning the ocean surface, the reception of messages will remain unattainable."
