Description
Summary:Urban Sensing has become an increasingly popular service in vehicular networks. It allows consumers to access a repository of data collected by sensors embedded in vehicles. Aggregation is a viable approach to convert the sensed data into a usable form. An efficient way to perform aggregation is to divide the network into a number of geographical regions, called aggregation regions. In this paper, we propose a novel mechanism to construct aggregation regions based on the location of RSUs (road-side units). Besides, we propose an optimization strategy to determine the optimal location of aggregation that minimizes the delay of vehicular communications.
