Method of Dynamically Determining the Nodes that Hold Advertisements Suitable for the User's Preference and a Relay Routing Method Based on Area Division

摘要

Mobile communications carriers are providing GPS-based, location-dependent advertisement delivery services as supplementary services. As the number of mobile terminal types and the number of mobile users increase, the need is rising for a network that can handle location-dependent traffic within a locality efficiently. This paper presents an ad hoc network for location-oriented advertisement delivery, with an advertising node installed in each shop in a busy shopping area. Specifically, it describes a way to express the user's preference, such as their hobbies, based on a Bloom Filter, and a way to dynamically determine the nodes that hold advertisements suitable for the preference of the target user. In addition, the paper also presents a routing method based on area division, which can reduce the number of relay nodes. It has been confirmed, by using simulation, that the proposed method reduces the number of relay nodes by about 70% compared with a case where messages are unicast to collect suitable advertisements.
