Investigating the Suitability of Delay Tolerant Networks for Broadcasting Tsunami Warnings in Palu, Indonesia

Adam Graham, Milena Radenkovic

Simulations of Epidemic and Spray and Wait DTN protocols show they are unsuitable for the tight time constraints of post-earthquake tsunami warnings in Palu but may apply to preceding earthquakes.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Results indicated that these protocols are not suitable for the tight time constraints of post-earthquake tsunami warnings with the currently available technology. However, they may have promising applications for the earthquakes that precede tsunamis.

C2weakest assumption

The pseudo-realistic simulation environment accurately represents the mobility patterns, node density, and network disruptions in Palu following an earthquake.

C3one line summary

Simulations of Epidemic and Spray and Wait DTN protocols show they are unsuitable for the tight time constraints of post-earthquake tsunami warnings in Palu but may apply to preceding earthquakes.
