Software defined networks for traffic management in emergency situations
Albert Rego, Laura García, Sandra Sendra, Jaime Lloret · 2018
When unexpected and unplanned events such as natural disasters, traffic accidents or even terrorist attacks happen, it is necessary to prepare a quick evacuation process and the provisioning of the quickest access routes for emergency services units. In these situations, it is important to have a centralized management of the entire scenario in order to organize the access to emergency services. This paper proposes an architecture based on Software Defined Networks (SDN) to manage and control the actions of emergency services and the evacuation plans. The proposal is based on the control of the deployed networks in Smart cities through a SDN. The control part of the SDN collects the data from the different Internet of Things (IoT) networks formed by traffic lights, traffic surveillance cameras, etc. and combines them to obtain the best and fastest evacuation routes and access roads to the emergency services units. The work shows the improvements in terms of delay when our proposal is used. The results are promising with improvements of the 30% in the registered delay.
