Enhancing Resilience in Communication Networks for Post-Disaster Response

Abstract

The conventional communication system may col- lapse due to natural or other man-made disasters. This break- down might make the disaster’s aftermath worse. Setting up an alternative or emergency communication system can be extremely helpful in alleviating suffering and making it easier to carry out rescue and relief operations. Concerning this situation, this work presents a resilient data transmission architecture for establishing communication in such a critical situation. This communication system provides a way to make communication between victims and rescuers in an infrastructure-less environment. The effect of mobility models is also examined by simulating the scenario using ns-3, which helps enhance the resilience of communication. For this simulation, the Random Walk 2D, Random waypoint, and Random direction 2D mobility models are considered mobility models. The parameters analyzed to assess the Quality of Service (QoS) of this communication architecture include Transmission Bit Rate, Receiving Bit Rate, Delay and Packet Loss Ratio (PLR). The study’s outcome involves determining the most suitable mobility model for the presented transmission architecture, based on its performance and suitability.
