چکیده

In this study, we analyze the extended real-time Polling Service (ertPS) algorithm, which is designed to support Voice-over-Internet Protocol (VoIP) services with various size of data packets and silence suppression in IEEE 802.16e system, by using a two dimensional Markov Chain where the grant size and the voice packet state are considered. In addition, we propose an enhanced uplink resource allocation algorithm, called the ertPS algorithm, for VoIP services by modifying the ertPS algorithm in IEEE 802.16e system. Then, we provide numerical results to verify the accuracy of our approximation analysis for the ertPS algorithm and the effectiveness of our ertPS algorithm.

VoIP services have been considered as one of the most important services in the next generation wireless systems. VoIP service requires the same quality of service (QoS) requirement as constant bit rate services. For this reason, the IEEE 802.16 standard has defined an unsolicited grant service (UGS) to guarantee the QoS. However, the UGS is inadequate to support VoIP services with silence supp...

An Efficient Uplink Scheduling Algorithm with Variable Grant-Interval for VoIP Service in BWA Systems

This letter proposes an efficient uplink scheduling algorithm for the voice over Internet protocol (VoIP) service with variable frame-duration according to the voice activity in IEEE 802.16e/m systems. The proposed algorithm dynamically changes the grant-interval to save the uplink bandwidth, and it uses the random access scheme when the voice activity changes from silent-period to talk-spurt. ...

Performance Evaluation of VoIP Traffic over the IEEE 802.16e Protocol with Different Modulation and Coding Schemes

Supporting as many Voice-over-IP (VoIP) users as possible in a Broadband Wireless Access network using limited radio resources is a critical issue. However, performance of VoIP services is affected by several parameters defined in the IEEE 802.16e protocol. In this paper we developed a theoretical model and an algorithm to evaluate the performance of some of the most important VoIP codecs. Simu...
