【摘要】：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.
[Abstract]:It is necessary for future users to complete personalized services by aggregating multi-terminals. However, mobile heterogeneous terminals can not sustain high-quality ubiquitous services. In this paper, a multi-terminal collaboration (MTS) mechanism is proposed. Based on the hierarchical model and the service quality standard model, a collaborative implementation process is established, which includes three modules: registration and initiation of the service MTS selection and maintenance. In order to improve the service performance, a timestamp detection mechanism and a time control window are added to the MTS selection core algorithm. Simulation results show that the MTS mechanism can quickly aggregate high quality execution terminals and ensure service continuity and smoothness. Compared with other methods, the MTS mechanism has better performance in terms of service rescheduling and delay.
