移动云计算的远程住宅网络多媒体服务发现与控制

Discovery and Control of Mobile Cloud Based Computing for Remote-Resident Multimedia Service

由于计算能力、NAT穿越、存储空间、异构网络环境接入等因素限制,传统设备难以实现针对远程家庭网络环境中的多媒体服务发现与访问.借助云平台在计算、存储以及网络接入等方面的优势,提出一种基于移动云架构的远程多媒体服务访问方法,重点考虑网络安全、远程服务发现、云存储、轻量级控制协议等方面内容.测试结果表明:提出的方案能够更有效地降低传输成本,且该方案较其他已有的方案更具有效性与可用性.

Due to realistic barriers（e.g. network heterogeneity, NAT traversal, limited computing/storage space, etc.）, it isdifficult to discover and access residential services from remote environment by using a majority of legacy devices（espe-cially mobile devices）. The architecture of a mobile cloud based service for enabling remote-resident multimedia servicediscovery and access was proposed. The main considered issues include： security, cloud-based storage, cloud-based re-mote service discovery and control, REST-based lightweight negotiation, etc. Mathematical evaluation proves that the pro-posed solution is capable of reducing transmission cost. Prototype implementation shows availability and efficiency of theproposed approach. The comparison work shows that this proposal could provide better customer services than other exist-ing solutions.
