摘要
综合业务模型和网络模型提出了面向多业务的终端聚合问题模型,并在此基础上,提出了一种面向多业务的终端聚合算法,包括多终端协同集合的构造与决策两部分.通过仿真与面向业务的终端组合模式及随机分配算法比较可知,所提算法具有更高的性能.
It is critical problem how to meet all requested ubiquitous services simultaneously in ubiquitous stub environment with resource-limited devices and bandwidth-limited network. To achieve this goal,we first formulate multi-devices cooperation problem with ubiquitous service model and network model. And then a devices aggregative mechanism is proposed to support two key modules of multi-devices cooperation set construction and decision-making. At last,the simulation is implemented with OPNET and Matlab.The result shows this mechanism has better performance than others.
