Abstract

The optimization of data gathering in VANETs is to save bandwidth consumption as much as possible. However, the QoI of data collected may not satisfy the requirement of routing guidance demanded by the user if it merely focuses on saving bandwidth consumption, resulting in the inaccuracy of routing guidance for the user. Therefore, we propose a framework of QoI-based data gathering and routing guidance, which can take the requirement of QoI into consideration in the process of data gathering. Firstly, the requirement of QoI is extracted from the QoS requirement of the user. Then QUERY with QoI constraints is distributed in the interested area. Finally, data of which QoI can satisfy the requirement is gathered through data aggregation by QoI-DG protocol used for routing guidance. Simulations show that our proposed solution achieves effective and efficient data gathering in VANETs.
