Location-based service (LBS) realizes information sharing based on each user's location and demand. However, LBS platform providers need to have abundant network resources since they have to replicate and disseminate the published content to the subscribers as a broker. Namely, a user or organization, who has few resources, is difficult to be a standalone LBS platform provider or content publisher without a broker since they need to deal with network traffic for the enormous subscribers, and they need to have a way to manage all of the subscriber's information. This letter proposes user-centric location-oriented content dissemination based on peer-to-peer and device-to-device communications.
