【摘要】 普适计算是“后PC”时代的产物 ,正在深刻地影响着计算机科学的许多方面 针对有线普适视频领域 ,从“分子化合”的思维角度出发 ,提出了分子化服务思想 ,并构建了分子化服务体系结构模型 ,继而提出了保证视频服务分子协同工作的差错控制算法 实验证明这一差错控制算法是有效的 ,基于分子化服务思想的有线普适视频服务模型也是可行的 ,并且能够有效降低普适设备的系统负载 .更多还原

【Abstract】 Pervasive computing is the result of post PCage ,and it is affecting many aspects in computer science Based on the thoughts of chemical combination ,a kind of thought of molecule service is proposed in the domain of the wired pervasi vevid eoservice And a wired net work hierarchical architecture for this thought is also constructed Moreover ,an error control algorithm is devised to handle the package- losing situation in the process of the communication between two service molecules The simulation experiment demonstrates that theerror control algorithm is effective and the wired pervasi vevideo service architecture based on molecule services can decrease the system’loadobviously更多还原
