The Junction Protocol for Ad Hoc Peer-to-Peer Mobile Applications
نویسندگان
چکیده
Junction is an application-level communication protocol and library designed for writing mobile applications for ad hoc groups without centralized application servers. We propose that applications be built using a generic switchboard service for communication. Each dynamic instance can designate a unique switchboard, hosted by a peer or by a third-party, for the session. Our convention of naming a session by a Junction URI, which encodes the location of the switchboard, enables a simple click-and-run user experience. The Junction abstraction allows developers a choice of switchboard implementations: XMPP for scalability, IRC for free availability, Pocket Switchboard for mobility, and OpenFlow, a software-defined network, for performance. Invitations to sessions can be carried over NFC, Bluetooth, or QR codes. Junction is available as open source for Android, iPhone and Javascript platforms. Over ten applications in multimedia sharing, games, communication, education, and for enhancing security for online transactions have been developed in Junction.

متن کاملProtocol for peer-to-peer networking in mobile environments
Peer-to-Peer (P2P) as well as mobile ad hoc networks (MANETs) follow the same idea of creating a network without the help of central entities. However P2P and MANETs operate on different network layers. A combination of both, creates new services and possibilities, but also faces several problems. Introducing P2P computing in ad-hoc networks without considering the particular requirements of ad...
متن کاملVerifiable Agreement: Limits of Non-repudiation in Mobile Peer-to-Peer Ad Hoc Networks
We introduce verifiable agreement as a fundamental service for securing mobile peer-to-peer ad hoc networks, and investigate its solvability. Verifiability of a protocol result means that the participants can prove that the protocol reached a particular result to any third party (the verifier) which was not present in the network at the time of the protocol execution.
