Multi-Resolution Data Management for Opportunistic Networking

In this work, we present a multi-resolution data management scheme for efficiently storing and diffusing information, which is originating from sensors and augmenting mobile applications. The proposed mechanism exploits the discrete wavelet transform properties for providing a location-dependent data management scheme, which alleviates the constraints on the storage resources needed for running context-aware mobile applications. The data management scheme has been implemented and evaluated by means of numerical simulations.
