Abstract

Given the high importance of communication for disaster management and recovery operations, it is essential to develop solutions for restoring network connectivity after natural catastrophes. We have used a disaster emulation framework built on top of the large-scale network testbed StarBED in order to virtually recreate a series of disaster conditions. Thus we could evaluate the potential of using Delay / Disruption Tolerant Network (DTN) protocols and inter-vehicle communication for post-disaster network recovery.

The results of our network emulation experiments prove that DTN in itself is a feasible alternative for network recovery. The objective assessment done using our emulation testbed on how communication performance depends on the mobility pattern of the vehicles and on their density can be used to make various practical decisions, for instance on how to manage the mobility of some of the vehicles in order to optimize network performance.
