利用跨层设计提高簇路由协议性能

Improving Performance of Cluster Based Routing Protocol using Cross-Layer Design

Kazem Jahanbakhsh, Marzieh Hajhosseini

摘要:

路由协议的主要目标是有效地将数据从源端传送到目的端。所有的路由协议在这一目标上都是一致的,但它们实现这一目标的方式却各不相同,因此路由策略对adhoc网络的性能有着至关重要的作用。大多数为adhoc网络提出的路由协议具有扁平结构。这些协议扩展控制开销分组以发现或维护路由。另一方面,许多基于层次的路由协议已经开发出来,大多数是基于分层设计。这些协议提高了网络性能,特别是当网络规模增长时,因为可以以聚合的方式处理有关网络的远程部分的细节。但是,还有另一种设计协议的方法,称为跨层设计。利用这种方法可以在协议栈的不同层之间进行信息交换,从而优化网络性能。在本文中,我们打算运用跨层设计来优化基于集群的路由协议(Cross-CBRP)。使用NS-2网络仿真器,我们评估簇头的变化率,吞吐量和分组投递率。比较表明,交叉CBRP具有更好的性能相对于原始CBRP。

英文摘要:

The main goal of routing protocol is to efficiency delivers data from source to destination. All routing protocols are the same in this goal, but the way they adopt to achieve it is different, so routing strategy has an egregious role on the performance of an ad hoc network. Most of routing protocols proposed for ad hoc networks have a flat structure. These protocols expand the control overhead packets to discover or maintain a route. On the other hand a number of hierarchical-based routing protocols have been developed, mostly are based on layered design. These protocols improve network performances especially when the network size grows up since details about remote portion of network can be handled in an aggregate manner. Although, there is another approach to design a protocol called cross-layer design. Using this approach information can exchange between different layer of protocol stack, result in optimizing network performances. In this paper, we intend to exert cross-layer design to optimize Cluster Based Routing Protocol (Cross-CBRP). Using NS-2 network simulator we evaluate rate of cluster head changes, throughput and packet delivery ratio. Comparisons denote that Cross-CBRP has better performances with respect to the original CBRP.
