Vehicular networks are distributed, self-organizing and highly mobile ad-hoc networks. Communication among networked cars is presumably one of the most important possibilities to enhance traffic safety. To achieve this, vehicles should be able to manage information like a black ice warning in a distributed manner. In addition, the publish/subscribe (Pub/Sub) paradigm allows for information filtering and tracking of changes in the information environment. For example, warnings could be sent to affected vehicles only or vehicles could track traffic changes. The approach presented in this paper utilizes structured peer-to-peer (P2P) mechanisms for distributed information management. To adapt to the highly mobile environment, the vehicular network is divided into segments which form separate, interacting P2P networks. The Pub/Sub functionality is built on top of these segments. This way, P2P-based Pub/Sub can be applied with no need to maintain an event distribution tree. The proposed approach enables vehicle-to-vehicle applications to publish information referring to certain areas or validity durations. Moreover, published information can be modified and deleted and solely interested vehicles can be notified about these events.
