This growth is due to the integration of voice and data traffic over the existing network infrastructure, low cost, and improved network management offered by the technology. This paper reports on the performance of VoIP traffic characteristics in a wired-cum-wireless Ethernet LAN. The effect of increasing the number of VoIP wireless clients, different voice codec schemes, and packet arrival distributions on system performance is investigated. Through various simulation experiments under realistic network scenarios, such as Small Office Home Office (SOHO) and campus networks, this paper provides an insight into the performance of VoIP over Ethernet LANs. Simulation results show that VoIP clients and voice codec schemes have significant effect on system performance. The authors preformed OPNET-based simulations to validate their experiments.<\/p>","DOI":"10.4018\/jitn.2012100101","type":"journal-article","created":{"date-parts":[[2013,2,15]],"date-time":"2013-02-15T22:54:56Z","timestamp":1360968896000},"page":"1-25","source":"Crossref","is-referenced-by-count":0,"title":["Performance of VoIP in Wired-Cum-Wireless Ethernet Network"],"prefix":"10.4018","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2770-8319","authenticated-orcid":true,"given":"Nurul I.","family":"Sarkar","sequence":"first","affiliation":[{"name":"School of Computing and Mathematical Sciences, Auckland University of Technology, Auckland, New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kashif","family":"Nisar","sequence":"additional","affiliation":[{"name":"School of Computing InterNetWorks Research Laboratory, University Utara Malaysia and School of Computing and Mathematical Sciences, Auckland University of Technology, Auckland, New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2432","reference":[{"key":"jitn.2012100101-0","doi-asserted-by":"crossref","unstructured":"Baratvand, M., Tabandeh, M., Behboodi, A., & Ahmadi, A.
