Towards declarative programming for mobile crowdsourcing: P2P aspects

Peer-to-Peer technologies have been widely used in networks which manage vast amount of data daily. The proliferation of mobile devices strongly motivates mobile peer-to-peer network (M-P2P) applications, with benefits from network effects. We argue that logic programming for crowd sourcing can be useful in peer-to-peer computing for querying and multicasting tasks shared over peer networks. We introduce a declarative crowd sourcing platform for mobile applications, which combines conventional machine computation and the power of the crowd in social networking, particularly in M-P2P networks. This paper discusses a simple extension of Prolog, which we call Logic Crowd, focusing on enabling goal evaluation over peers in mobile peer networks. Additionally, we demonstrate that logic programming for crowd sourcing can be useful in peer-to-peer computing for querying and P2P style of task sharing over short-range networks. In this paper, we illustrate the potential of our approach via programming idioms, a prototype implementation and scenarios.
