A content-aware multimedia accessing model in ad hoc networks

In this paper, we show that data content distribution can be employed to facilitate content-based multimedia retrieval in ad-hoc networks. It is challenging to perform content-based multimedia retrieval in ad hoc networks due to the dynamic network topology. The autonomy and heterogeneity of data sources introduce additional complexity to this task. Motivated by the data organization methodology of the summary-schemas model (SSM), we proposed a logic-based content summary framework that is able to represent semantic contents of multimedia data using concise logic terms. Furthermore, we proposed a virtual infrastructure to cluster mobile nodes based on semantic contents. The proposed framework has been simulated, and the simulation results are presented and analyzed based on various performance metrics.
