Publish/subscribe notification middleware for vehicular networks

ABSTRACT

There is a large number of interesting applications for vehicular networks: traffic information dissemination, warnings, free parking spots finders, fuel prices advertising, etc. The Publish/ Subscribe (P/S) communication paradigm enables the application developers to easily design flexible notification systems. Furthermore, it enables the drivers/vehicles to indicate their interests about certain types of notifications (e.g. receive warnings concerning traffic jams only within 1km from the vehicle's route). And finally, P/S is an asynchronous communication protocol (spatial and temporal decoupling) that is suitable for the delay-tolerant network conditions.

Our main goal is to design a P/S Middleware for vehicular networks that considers location and time in its primitives. We would like to enable the application developers to easily publish notification in specific location by treating location as context. We will use subscriptions and the navigation system to automatically express interests on the affected vehicles and to filter incoming notifications. Additionally, our middleware incorporates the appropriate communication mechanisms that implement the tasks instructed by the middleware primitives.
