SPID: A Novel P2P-based Information Diffusion Scheme for Mobile Networks

In this paper, we propose a novel peer-to-peer based information diffusion scheme for mobile ad hoc networks. Due to mobility and bandwidth constraints, it is not always possible to share a complete content within a single transmission from one mobile device to another. To address this problem, we introduce segmentation of contents into smaller pieces for efficient information exchange. In mobile ad hoc networks, since it is impossible for a node to know the content of every other node in the network, we propose a Spatial-Popularity based Information Diffusion (SPID) scheme that determines urgency of dissemination of content according to the necessity in a neighborhood. Substantially, the segmentation policy and popularity based information dissemination reduce content acquiring time for each peer. Extensive simulation studies demonstrate that the proposed scheme is efficient in data distribution in mobile ad hoc networks, and prove superiority to other existing methods.
