LL-Net: Location-based Logical P2P Network for Mobile Environment
Yu Kaneko, Kaname Harumoto, Shinji Shimojo, Shojiro Nishio · 2004
With the popularization of today's mobile devices such as PDAs, cellular phones, and laptop PCs, the environ- ment that enables us to publish and utilize information via the Internet has been actualized. In the near future, other kinds of devices such as network-enabled appliances and sensors will also be connected to the Internet. Users will be able to get various kinds of information such as their surrounding contexts like location and weather from other users via the Internet, and many context-sensitive services that utilize these information will be developed. The context-sensitive services often require retrieval of location-based information because context information is often location-dependent. We consider P2P networking to be promising in the environment mentioned above, but the existing flooding-based retrieval algorithms commonly have a problem that they generate a huge amount of network traffic. To cope with this problem, we propose a P2P overlay network construction method based on device locations to realize efficient retrieval of location-dependent information.
