Abstract

<p>If mobile nodes such as vehicles and pedestrians deliver information by direct wireless communication between mobile nodes and movement of mobile nodes carrying information, disordered and unnecessary spread of information arises. To overcome this problem, a method to permit mobile nodes to transmit information only in transmittable areas has been considered. This method is called Information Floating. Theoretical analysis of Information Floating is important because it is necessary for some purposes such as control of the size of a transmittable area, and has been studied in various situations. In this paper, we consider Information Floating by pedestrians walking toward opposite directions along a street, and theoretically analyze performance of Information Floating under the assumption that the communication range changes due to the positional relationship between mobile nodes because the mobile nodes themselves become obstacles. From the numerical results, we show that degree of effects of the assumption that mobile nodes themselves become obstacles on performance of Information Floating depends on the densities of mobile nodes and the difference between the densities of mobile nodes moving toward the opposite directions, and show effectiveness of the proposed theoretical method. Based on these results, we show a method to decide the size of a transmittable area suitable to the situation where mobile nodes themselves become obstacles.</p>
