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.
Aggregating multi-terminals to complete personalized services is a necessary requirement for ubiquitous services for future users, however, mobile heterogeneous terminals can not sustain high-quality ubiquitous services continuously.Therefore, a multi-terminal coordination (MTS) mechanism is proposed to be layered Model and quality of service model based on the establishment of collaborative implementation process, including business registration and launch, MTS selection and maintenance of three modules in the MTS core algorithm to select the timestamp-based access time and path control window to improve Service Performance Simulation results show that MTS mechanism can converge high-quality execution terminals quickly and ensure service continuity and smoothness. Compared with other methods, MTS mechanism has better performance in terms of service re-establishment and delay.
