支持延时约束的覆盖多播路由协议的研究
摘要
研究有度和延时约束的覆盖多播路由问题
提出了一个新的覆盖多播路由协议-延时受限的树协议(DBTP)。该协议采用分布式和树优先的策略
使多播组成员之间能自组织地构建一棵基于源的覆盖多播树。DBTP协议采用了一种新的启发式局部优化算法
通过调节启发因子
能灵活地在延时和代价之间进行折衷。仿真实验表明
无论在静态还是动态节点模型下
选择适当的启发参数
DBTP都能获得较高的节点接纳率。
Abstract
The degree and delay constrained routing problem in overlay multicast was studied
and a new overlay multicast routing protocol called delay bounded tree protocol (DBTP) was proposed. Adopted distributed and tree-first strategies
the protocol enabled members of a multicast group to self-organize into a sourced-based overlay multicast tree. DBTP used a new heuristic local optimum algorithm
which could make trade-off between delay and cost of the multicast tree by adjusting a heuristic parameter. The simulation result shows that DBTP can both achieve the admission rate of members highly under whether static or dynamic node model through choosing a proper value of the heuristic parameter.
