Due to the prevalence of wired and wireless access to Internet and fast grow-up of Internet of Things (IoT), it would be a trend to integrate present isolated video surveillance systems by applying distributed computing environment and to further gestate diversified multimedia intelligent surveillance (MIS) applications in ubiquity. In this dissertation, we firstly discuss the surveillance service models and propose a multicast based ubiquitous video surveillance (UVS) architecture with scalability, ubiquity and privacy. We also constructed an experimental test-bed for UVS system with three kinds of services, fire detection, fall-incident features and video recording, to demonstrate the effectiveness of the proposed architecture. Besides, we took the advantage of multipoint-to-point (MPP) connections to aggregate more bandwidth to gain user-perceived Quality of Experience (QoE) and network Quality of Service (QoS) for the surveillance cameras that has limited uplink bandwidth. A forward error avoidance mechanism is proposed within P-R2CP (Prioritized Radial Reception Control Protocol), a receiver-centric transportation protocol with priority consideration, to be feasible for IoT MIS applications. The simulation result demonstrates the effected frames are significantly 74.4% decreased and improves the QoS and QoE.1772343 bytesapplication/pdf論文公開時間: 2015/8/20論文使用權限: 同意有償授權(權利金給回饋學校)智慧型監視系統物聯網多點對點通訊服務品質用戶感受intelligent surveillance systemInternet of Thingsmultipoint-to-point communicationquality of servicequality of experiencethesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/271476/1/ntu-104-D95525010-1.pdf
