摘要:
针对现有MAP选择算法的评价指标不能直接反映用户的实际通信情况的问题,提出了新的指标——会话阻塞率.利用排队理论推导出会话阻塞率的数学期望公式,分析得到影响会话阻塞率的4个因素:会话频率、持续时间、节点的速度、MAP的层次.同时根据实时性需求和会话阻塞率间的关系,提出了基于会话特征的MAP选择算法.该算法采用了基于速度选择算法的节点分类机制,并在选择条件上增加了节点的部分会话特征.通过实验对这2种算法的性能进行比较和分析,结果表明本算法能够为用户的实时性需求提供更好的支持.
Abstract:
Since the current evaluation guidelines for mobile anchor point(MAP)selection algorithms can not manifest the actual condition of user’s communication, a new guideline, session blocking rate(Tint), is proposed. According to the queuing theory, the derived mathematical expectation of Tint, is related to four factors: session ratio, session duration, the speed of mobile node and the layer of MAP. In order to adjust the Tint to the user’s requirement for real time communication, session-character based MAP selection algorithm is proposed. This algorithm adopts the node classification mechanism, which is used in speed-based selection algorithm, and adds some session characters to the selecting conditions. From the numeric results,it is concluded that session-character based MAP selection algorithm can select the proper MAP according to user’s requirement for real time communication.
