Information aggregation is used to fuse interrelated data items collected from different nodes before redistributing them. Thus, using aggregation the number of transmissions and the communication overhead can be reduced significantly. Particularly for applications which require periodic dissemination of information into a large region, aggregation becomes prerequisite. Let us consider an example of self-organized infrastructure less traffic information system where each vehicle periodically disseminates its speed, position and information about road conditions. The aim is to design such data aggregation technique that not only use low bandwidth for data dissemination after aggregation process but also use low bandwidth for data collection from source nodes as well. As VANET environment has limited bandwidth this data aggregation becomes the need of hour for efficient data processing and dissemination without network overhead. In this work we have proposed a cluster based data aggregation technique where vehicles are divided into autonomous clusters headed by cluster-head. Data is send to cluster-head that perform the aggregation of data and dissimulate it into network.
