Abstract

In Mobile Ad-hoc Network (MANET), there is no centralized infrastructure. Nodes are free to move anywhere in the network so routing is very challenging task. Mobile nodes are responsible for link failure, interference and congestion. Congestion is one of the main reasons for degradation of performance of network. When traffic in the network increases over the stipulated capacity, congestion takes place. The traditional routing protocols are not effective for addressing the received signal strength related problems. In this paper, authors designed a new algorithm using the combination of Ad-hoc on Demand Distance Vector (AODV) and Cross layer design approach. It is referred as Congestion Control AODV (CCAODV) approach. It is used to avoid link break in MANET. Received signal strength is used as cross layer design parameter. The CCAODV protocol creates strong and stable route by using signal strength of node. The signal strength mainly depends on the parameters like transmission power of node and distance between two nodes. The cross layer design approach is tested by using Ns 2.35 simulator and compared with the AODV routing protocol.

manet中拥塞控制的跨层设计方法

在移动自组织网络(MANET)中，没有集中的基础设施。节点在网络中可以自由移动，因此路由是一项非常具有挑战性的任务。移动节点负责链路故障、干扰和拥塞。拥塞是导致网络性能下降的主要原因之一。当网络中的流量增加超过规定的容量时，就会发生拥塞。传统的路由协议不能有效地解决与接收信号强度相关的问题。本文将Ad-hoc随需应变距离向量(AODV)与跨层设计方法相结合，设计了一种新的算法。它被称为拥塞控制AODV (CCAODV)方法。它用于在MANET中避免链路中断。接收信号强度作为跨层设计参数。CCAODV协议利用节点的信号强度创建强而稳定的路由。信号强度主要取决于节点的传输功率、节点间的距离等参数。利用Ns 2.35仿真器对跨层设计方法进行了测试，并与AODV路由协议进行了比较。
