Abstract :
In an ad hoc network, the topology varies as a result of the mobility of its mobile hosts. Consequently, the task of performing ad hoc network routing is more complex and less efficient. Many ad hoc network routing protocols have been proposed. However, more work is required in developing scalable ad hoc routing protocols that support quality-of-service (QoS). Recently, our study shows that link stability (in term of link survival time) has great impact on QoS performance of routing in ad hoc networks. We developed a number of models which effectively estimate link stability for different network movement patterns. By implementing link stability, which is a standalone network parameter, the QoS performance of varieties of ad hoc routing algorithms could be improved when networks are subjected to topological changes, to variations in traffic loading patterns (including a multitude of traffic classes). In this paper, we show that QoS performance of AODV is improved by implementing link stability parameter.
