International audienceAudio streaming over wireless local area network (WLAN) has an ability to transmit audio data ranging from short messages to music station. A popular application of this is in setting up a community radio, which is in demand, especially in developing countries where frequency spectrum management is still problematic. Audio streaming has to assure high quality of content reception without any packet loss, if possible. One such suitable coder-decoder (CODEC) is the Advanced Audio Coding (AAC). Packetization interval for audio streaming is usually set at a default value of 20 ms. This work develops an AAC Audio Streaming over WLAN 802.11g. It studies the effect of different packetization intervals has on the maximum number of possible connections (i.e. receivers) without any packet loss. The simulated environment comprises of 1 access point with 300 m2. Connecting media server to access point via wireless link is adopted for its mobility and ease of deployment in rural area. The range of packetization intervals under this study is from 20 ms. to 200 ms. The study reveals that the commonly use default value of 20 ms. can manage up to 13 connections. Under the scenario of this study, it was found that the best packetization interval is 70 ms. with the maximum of 33 connections. The study also reveals that packet delay is not an issue in this approach as all are under the acceptable standard of 400 ms

“…In relation to OMNeT++ and its simulation models, a number of researchers worked on validating the reliability and accuracy of OMNeT++. For example, Bredel and Bergner 18 performed a measurement study of wireless networks in a highly controlled environment to validate the IEEE 802.11g model of OMNeT++. They used metrics like throughput, delay, and packet inter-transmission to compare the measurement results with identical simulations.…”

802.11 wireless simulation and anomaly detection using HMM and UBM

Despite the growing popularity of 802.11 wireless networks, users often suffer from connectivity problems and performance issues due to unstable radio conditions and dynamic user behavior, among other reasons. Anomaly detection and distinction are in the thick of major challenges that network managers encounter. The difficulty of monitoring broad and complex Wireless Local Area Networks, that often requires heavy instrumentation of the user devices, makes anomaly detection analysis even harder. In this paper we exploit 802.11 access point usage data and propose an anomaly detection technique based on Hidden Markov Model (HMM) and Universal Background Model (UBM) on data that is inexpensive to obtain. We then generate a number of network anomalous scenarios in OMNeT++/INET network simulator and compare the detection outcomes with those in baseline approaches—RawData and Principal Component Analysis. The experimental results show the superiority of HMM and HMM-UBM models in detection precision and sensitivity.

“…For example, paper [3] compares a four node 802.11g network with an OMNeT++ simulator (based on inet + cocorada). The nodes were in an anechoic chamber and separated by only 0.5-1.5m, giving near perfect connectivity.…”

Simulation is an essential tool for evaluating the performance of wireless protocols and applications because of its cost effectiveness and its high level of control over the simulated system. As the research community envisions increasingly complex applications in areas like mobile social networks and wireless sensor networks, the need for trustworthy simulation of core communication protocols increases.This paper presents a comparative evaluation of several IEEE 802.11 and IEEE 802.15.4 simulators. The paper defines a set of simple experiments that are intended to highlight handling of backoff and contention.A wide variation in results is observed. Although this is partially explained by differences in wireless communication models, the experiments also reinforce existing concerns about the reliability of simulation results. A long term goal is that this methodology will encourage the adoption of common test and evaluation scenarios. This would lead to better understanding of simulation behavior and help to improve the quality of -and confidence in -simulation results.
