The recent advances in wireless client devices, that host heterogeneous wireless technologies spanning from IEEE 802.11 (WiFi) and Bluetooth (BT) to cellular 3G and beyond, and the crucial role of multimedia communications in our society are motivating new multimedia provisioning scenarios in which multimedia content delivery is tailored depending on client location, with different goals, from personalized location-dependent advertising/marketing to enhanced forms of touristic assistance.
The purpose of the
called Localized rElay-based mobile Multimedia (LEM) middleware is to provide effective support for seamless multimedia flow delivery in highly populated regions where specific contents should be distributed to geographically bounded Areas of Interest (AOIs), such as personalized and different promotional videos toward the areas used by different exhibitors in an exhibition pavilion.
LEM significantly differs from state-of-the-art work by combining the following original technical aspects:
LEM is the first proposal in the field for completely decentralized content delivery in dense AOI. LEM is a real and ready-to-deploy content distribution solution: we both validated the proposed support infrastructure in extensive ns-2 simulations and implemented it as an open-source middleware.
