• Abstract:

  Publish-subscribe middlewares are important communication models for smart devices in the Internet of Things environment. Publish-subscribe middlewares connect applications and service providers while hiding questions of connectivity, security and event handling. In this context, a publish-subscribe middleware manages events sent to and from smart city applications in order to offer common services and facilitate their deployment and development. Emergency services can adopt the Publish-Subscribe paradigm to notify mobile units as soon as possible with minimal human intervention. Factors such as proximity to the emergency event and traffic conditions can be considered when selecting the mobile units to handle the event. This paper presents a survey of publish-subscribe middlewares in smart cities, with an overview of the principles, architectures, and perspectives of challenges for emergency services.
