Abstract :
In this paper, we propose and study a novel distributed traffic information system. The contributions of the paper include a road-network-aware (RNA) information publication protocol, a distributed query processing protocol with transient memory, and an adaptive interaction model between the two, all in the context of a distributed traffic surveillance infrastructure. Our study focuses on (1) the impact of various information demand characteristics on dissemination strategies, and (2) the adaptive optimal strategies in a distributed manner without prior knowledge of information demand characteristics. Both theoretical and simulation results are presented.
