“…Concerning buffer size, the default size is of 50 packets (204800 bits for a packet size of 512 bytes) in ns-2, whereas the default value in OPNET is 256000 bits. To make meaningful comparisons using OP-NET, those parameters were set to the default values of ns-2, that is, the values used in [5].…”

“…In the experiments using ns-2 in [5], each source QSTA supports up to four different AC flows. Unexpectedly, when doing the same with OPNET, the results obtained showed high variability, and the ranking of ACs in terms of throughput seemed to be random in most cases.…”

“…For IEEE 802.11e evaluation in ns-2 we relied on the extensions from [20], while for OPNET we relied on the IEEE 802.11e model that is built-in. Results obtained with the ns-2 simulator have already been published in [5]. The motivation of this paper is to repeat all the experiments under the same conditions using OPNET, in order to validate the accuracy of both simulators for some particular MANET scenarios.…”

In this work we present the results of a comparative study between two well-known network simulators: ns-2 and OP-NET Modeler. In particular, we focus on a performance evaluation of the IEEE 802.11e technology on Mobile Ad-hoc Networks (MANETs) in both stationary and mobile scenarios. The paper describes the tested scenarios in detail, and discusses simulation results obtained with OPNET Modeler, comparing them with those obtained with ns-2. The performance of IEEE 802.11e in the presence of legacy IEEE 802.11 stations is also analyzed. Due to the significant differences between both simulators, we enumerate those changes required so as to make results obtained via both simulators comparable. The results that have been reached support the conclusion that the behavior of both simulators is quite similar in general.

“…There is also a set of papers assessing the EDCA scheme in multi-hop networks, where it presents a poor performance due to throughput degradation as the number of hops increases and also due to the hidden terminal problem, which increases the collision probability [34,35]. In addition, as presented in [36,37], RTS/CTS mechanism does not improve the network communication performance when considering an ad hoc/mesh network.…”

With the widespread deployment of wireless mesh networks (WMNs) in industrial environments, real-time (RT) communication may benefit from the multi-hop relaying infrastructure provided by WMNs. However, RT communication must be able to coexist with non-RT traffic sources that will interfere with RT communication. Within this context, this paper assesses the impact of interferences caused by non-RT traffic sources upon RT traffic in IEEE 802.11s mesh networks. Through an extensive set of simulations, we assess the impact of external traffic sources upon a set of RT message streams in different communication scenarios. According to the simulation results, we infer that RT traffic in 802.11s networks may be highly affected by external interferences, and therefore, such interferences must be taken into account when setting-up 802.11s networks. By varying the network load imposed by external interferences, we provide some useful hints about utilization thresholds above which the network can no longer reliably support RT traffic. We also present insights about the setting-up of some network parameters in order to optimize the RT communication performance.

“…In a previous work [1] we analyzed the performance of IEEE 802.11e [8] in MANET environments, concluding that with an appropriate admission control mechanism, such technology would be able to offer good QoS support in envi-ronments with distributed channel access such as MANETs.…”
