An overlay-based service architecture for distributed video surveillance system
نویسندگان
چکیده
In this paper, a service architecture based on overlay network was presented. The architecture was designed to build a novel distributed video surveillance system, called as Etouch. In the model, the system is divided into three layers: underlying network layer (UNL), overlay service network layer (OSNL) and application layer (AL). OSNL is composed of many intelligent overlay nodes mapped by underlying network layer. Overlay nodes provide all kinds of media service for surveillance application in AL. OSNL allows media service composition of distributed stream processing applications dynamically. And a load balance of QoS-aware service composition algorithm (LBQSC) is employed to satisfy their end-to-end QoS demands. Large-scale experimental results demonstrate the scalability, efficiency and performance of the E-touch system.

Distributed architecture offers many advantages compared to centralized architecture in terms of providing multimedia services. However, as a trade-off, distributed architecture requires that peers contribute a portion of their bandwidth and computational capacity to maintain the mutual overlay interconnection. This requirement develops into a serious problem for mobile users and wireless infra...
