【摘要】 移动自主网络中的大多数多路径路由方案几乎没有考虑流量分配和负载均衡问题。显然,无论路径质量好坏给每条路径分配相同的负荷,会大大降低多路径路由机制的性能,最后会大幅增加网络的通信开销和节点的处理开销。围绕这些问题,提出了一个基于动态拓扑的多路径自适应动态流量分配方案,根据路径质量的权重来动态地给多条路径分配数据流量的比例。大多数情况下仅用局部的信息做路由决定,因此大大减少网络开销。在OPNET模拟平台中实现了这个协议,结果表明,该方案对于MANET网络来说的确是一个可行的方法。更多还原

【Abstract】 In order to circumvent these problems that led to impose both communications overhead on the network and processing overhead on node in most MANET multipath routing schemes proposed so far when the same size load was distributed into the various paths regardless of the qualities, a scheme called adaptive dynamic traffic distributing multi- path routing(ADTDMRP)was proposed, which distributed by proportioning flows among multiple paths dynamically based on the weight value of each path. It made routing decisions using only “local” information at the most of time and thus re- ducing the network overhead. By implementing the algorithm on the OPNET modeler, the results demonstrate that adaptive dynamic traffic distributing multipath routing is indeed a viable alternative to MANET routing approach.更多还原
