Abstract

Mobile video surveillance systems are ubiquitous nowadays and are used in both civilian and military settings such as public safety and security. They are real-time Machine-to-Machine (M2M) video applications that consume a large amount of network bandwidth and are sensitive to delay, jitter and packet loss. Evolved Packet Core (EPC) is the new core network for the next generation network. It enables the design and implementation of new innovative applications that are aware of data flows. It also enables services provisioning with both guaranteed and differentiated end-to-end Quality of Service (QoS).
This thesis proposes a novel RESTful web services based system architecture for mobile video surveillance applications over EPC. The proposed architecture enables mobile video services provisioning with guaranteed and differentiated QoS, something which is not possible in the state-of-the-art. The main component of the architecture is a Service Delivery Platform (SDP), made up of a QoS enabler and a streaming enabler. The QoS enabler exposes EPC network resources and QoS capabilities in order to allow the surveillance application to provide differentiated QoS to various end-users. The streaming enabler enables live and on-demand video streaming as well as video recording for later viewing. The SDP components (i.e. QoS enabler and streaming enabler) can be accessed via Representational State Transfer (REST) interface. In addition, a proof of concept prototype has been implemented deployed to demonstrate the feasibility of the proposed architecture. Performance measurements have also been made to evaluate the viability of the architecture.
