Optimal Relation between ART and Mobility & Transmission Range at Default QualNet & Calculated Transmission Powers

Abstract

Abstract-In Ad-hoc On-Demand Distance Vector (AODV) routing, it is suggested that the value of Active Route Timeout (ART) should be a constant (i.e. generalized for all kinds of applications or traffic generators). However, it has been observed from the current work that the choice of ART value according to network behavior and traffic generators may significantly increase the network performance. The presented work in this paper tries to analyze an optimal relation between the ART and node"s mobility & transmission ranges in which AODV network provides best performance. Here, AODV network performance is subjected to IEEE 802.11 MAC protocol under random waypoint topology. This paper uses the QualNet simulation tool to carry out the results, and the graphs have been prepared from obtained simulation results by using D-plot. Moreover, the Constant bitrate (CBR) traffic generator has been provided to generate the traffic between the mobile nodes and performance observation is based on throughput metric.

A Survey on Parameters Affecting MANET Performance

“…Allowed hello loss: If a node does not receive any contribution to routing activities from its direct neighbor node for more than (HelloInterval × AllowedHelloLoss), the node should assume a link failure to this neighbor [17]. The allowed hello loss default value is two link failures.…”
