VoIP is seen as a short-term and long-term transmission for voice and audio traffic and is moving on Wireless Local Area Networks (WLANs) based on IEEE 802.11 standards. Currently, packet scheduling algorithms like Weighted Fair Queuing (WFQ), was mainly designed to provide the bandwidth reservation. The Strict Priority (SP) is low-cost to maintain the delay sensitive voice traffic. Also, a number of research scheduling solutions have been proposed like General processor sharing (GPS), Deficit Round Robin (DRR), Contention-Aware Temporally fair Scheduling (CATS). Unfortunately, the current scheduling won\u2019t be able to handle the VoIP packets properly and they have drawbacks over real-time applications. The objective of this research is to propose a Fourth Stage of Voice Priority Queue (VPQ) packet scheduling and algorithm to ensure more throughput, fairness and efficient packet scheduling for VoIP performance of queues and traffics. A new scheduler flexible which is capable of satisfying the VoIP traffic flows. Experimental topologies on NS-2 network simulator were analyzed for voice traffic.<\/p>","DOI":"10.4018\/jitn.2012040104","type":"journal-article","created":{"date-parts":[[2013,2,5]],"date-time":"2013-02-05T22:21:46Z","timestamp":1360102906000},"page":"48-63","source":"Crossref","is-referenced-by-count":0,"title":["Fourth Stage of Voice Priority Queue for VoIP over WLANs"],"prefix":"10.4018","volume":"4","author":[{"given":"Kashif","family":"Nisar","sequence":"first","affiliation":[{"name":"University Utara Malaysia, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2432","reference":[{"key":"jitn.2012040104-0","unstructured":"An, C., & Soung Chang, L.
