Marry your architecture in haste, and you can repent in leisure. You likely have made it to where you are by paying your dues: After several years, you might think that you have seen it all—"Bring on new technologies, stormy political waters, and ugly legacy systems to contend with!
This architecture allows us to perform various realistic in contention-free conditions. III, is proposed to effectively capture the properties of contention-based media access for wireless channel.
However, before widely deploying multi-hop wireless Link State Routing Protocol . AEROMAN Network emulation is an experimental technique bridging the gap between simulation and real-world experiments, and AEROMAN is a highly scalable architecture that can sup- thus, it has significant impact on the wireless research commu- port the design and development of wireless devices and nity.
As in real-world testbeds, application testing can be run protocols by seamlessly incorporating real applications and in real-time in a more realistic environment, for example, ad- protocol implementation with simulation models.
Our goal is hering to hardware specific limitations, using real protocol im- to allow native wireless routing codes such as OLSR to run plementations, etc. Similar to simulation, the wireless medium on StarBED facility for evaluation purposes.
The routing codes run on StarBED PCs, that are connected The only thing affecting the accuracy of the model is the by Ethernet switches, and properties of the links such as fidelity of the emulation layer control. Emulation experiments bandwidth, delay, packet loss rate, etc.
The switching process description. From the view point of the routing agents, it seems from emulation to real-world deployment is accelerated, since that they are working on a real wireless network with typical most part of the codes can be reused.
Further discussions about each type ture, which allows us to perform experiments with multi-hop are presented in Section V.
Only distributed emulators are able wireless networks as follows: Traffic model see Section III.
Then, Dummynet Configuration The design in this paper is particularly dedicated to pro- module wireconf configures the wired-network emulator active routing protocols such as OLSR etc. These parameters represent links parameters in the contention- Topology info.

For broadcast traffic, since dummynet. The purpose of this module is to applied when packets arrive at the destination through a set of send multicast manner the traffic information of this node dummynet pipes.
The traffic information contention-free conditions. Hence, to take into account is achieved by querying statistical information of dummynet the effects when there are several nodes competing for pipes.
This module on the channel. Statistics Processing module periodically collects from dummynet the statistic information of traffic sent collects statistical information of traffic at both current node by this node, such as channel utilization, number of packets, and average packet size, and sends them to other nodes in 2 Physical layer to data link layer: All the link param- multicast manner.
This module recomputed according to the channel utilization. From our collects the statistical information which is multi-casted by point of view, there are two parameters to be changed, namely other nodes, and stores it in Real-time Traffic Information frame error rate and defer time.
Frame error rate is change due database. This module is created to frames which are sent by other nodes at the same time. The overcome the fact that QOMET cannot take into account the reason of changing in defer time is rather straightforward: The following paragraphs describe how to adjust these performing an experiment are the raw parameters of all possi- parameters.AEROMAN: A Novel Architecture to Evaluate Routing Protocols for Multi-Hop Ad-Hoc Networks.
