聚合多终端完成个性化业务是未来用户对泛在业务的必然要求,然而移动的异构终端无法持续地支撑高质量的泛在业务.为此提出了多终端协同(MTS)机制,以分层模型和业务质量标准模型为基础建立协同实现流程,主要包含业务的注册与发起、MTS选择和维护3个模块.在MTS选择核心算法中加入基于时间戳的探路机制和时间控制窗口,以提高业务性能.仿真结果表明,MTS机制能较快聚合高质量执行终端,保证业务持续性和平滑性,与其他方法比较,在业务重调和时延方面有更好的性能.
Collaboration for a ubiquitous service is an inevitable demand of users in the future. This paper put forward the multi-terminal synergy( MTS) mechanism for ubiquitous service. With a hierarchical model and a service quality model adopted,MTS is composed of three modules. Pathfinding mechanism based on time stamp and time control window are added to the core algorithm. The result shows that MTS can quickly choose high quality executive nodes,ensure the service continuity and smoothness. Compared with others,it improves the performance in readjustment and delay.
