This paper proposes a novel peer-to-peer communication framework to realize geographical location oriented networks called G-LocON. Location based services have been getting popular as typified by ridesharing and mobile games. Although these services have to construct geo-location oriented networks based on users' geographical locations, they completely rely on client/server models to communicate with neighboring terminals. G-LocON, the proposed communication framework, provides geo-location oriented device-to-device communication only with the current wireless technologies such as LTE and Wi-Fi, cooperating with global positioning system and peer-to-peer overlay networking. We introduce a location tracker, which maintains location information of user devices and helps them find the neighboring devices. After obtaining the neighbor peers list, each device can establish peer-to-peer connections to the neighbors and then directly communicate to them without relaying any server. G-LocON will thus realize a kind of mobile ad-hoc network in which devices in a focusing area can directly communicate among them. We developed the Android application to implement the G-LocON framework. The performance evaluation in the actual environment verified the usefulness of the proposed system with admissive transmission delay.
