“…In particular, recent research on service models in which users actively or passively act as data providers or relayers based on the people-centric networking paradigm [ 4 , 5 ], which includes users and their devices in the system components, has been conducted for the purpose of effectively utilizing user-owned device resources. With this in mind, we are now conducting advanced research and development into a sensor-based application building model known as a contract-oriented sensor-based application platform (COSAP), which can flexibly control data disclosure settings based on the concept of “contracts” between data consumers and providers [ 6 ]. A COSAP is an infrastructure-less data distribution platform in which sensor data can be freely distributed by participating in peer-to-peer (P2P) networks built between users.…”

As smartphones and other small portable devices become more sophisticated and popular, opportunities for communication and information sharing among such device users have increased. In particular, since it is known that infrastructure-less device-to-device (D2D) communication platforms consisting only of such devices are excellent in terms of, for example, bandwidth efficiency, efforts are being made to merge their information sharing capabilities with conventional infrastructure. However, efficient multi-hop communication is difficult with the D2D communication protocol, and many conventional D2D communication platforms require modifications of the protocol and terminal operating systems (OSs). In response to these issues, this paper reports on a proposed tree-structured D2D communication platform for Android devices that combines Wi-Fi Direct and Wi-Fi functions. The proposed platform, which is expected to be used with general Android 4.0 (or higher) OS equipped terminals, makes it possible to construct an ad hoc network instantaneously without sharing prior knowledge among participating devices. We will show the feasibility of our proposed platform through its design and demonstrate the implementation of a prototype using real devices. In addition, we will report on our investigation into communication delays and stability based on the number of hops and on terminal performance through experimental confirmation experiments.
