A Dynamic P2P Resource Sharing Architecture for Adapting MPEG-21 Digital Items in Mobile Networks
Tz-Heng Hsu,Yueh-Heng Li 보안공학연구지원센터 2008 International Journal of Hybrid Information Techno Vol.1 No.4
Due to the vast size, real-time requirement, QoS consideration, etc., of mobile devices, techniques like multimedia transcoding are developed to satisfy the need of surfing the multimedia services using mobile devices. In this paper, we propose a P2P resource sharing architecture for adapting MPEG-21 digital items in mobile networks. In the proposed P2P architecture, digital items can be shared among heterogeneous networking environments. Meanwhile, digital items can be dynamically adapted according to the networking situation and user’s device capacity. The proposed P2P system introduced a new cache and replacement algorithm for managing adapted digital items, which can smooth the transcoding delay variations of digital items during subsequent resource sharing among different networked devices.
