“Content Cruising System (CCS)” is developed as a decentralized and autonomous distribution system for location-based contents. The content put into CCS carries itself to the destination location and tries to remain there by continual wireless ad-hoc communications among mobile nodes. Focusing on the density of nodes, to tackle the Broadcast Storm problem is imperative. CCS has an avoidance mechanism of redundant transmissions constructed by cooperation of its pre- loaded algorithms, therefore CCS can avert the Broadcast Storm problem regardless of the increase in the number of nodes. Through the experiments with a network simulator, it was confirmed that the mechanism functioned as planed, packet loss on the air was kept lower, the time taken to acquire flowed contents was shortened considerably when the mechanism was applied. In this paper we describe the basic operation of the mechanism and examine the effectiveness of it from various angles.
