,Quality of Service Management—Design Issues, categories, metrics, and policies are defined and discussed with respect to VoIP applications. QoS implementation policies are introduced based on a QoS framework. The fundamental difference with QoE is also highlighted. Finally, the current approach of problem solving in regard to QoS management i

The primary factors involved in effective real-time communication, namely delay and loss, must be within certain controlled limits in such a scenario. This chapter analyzes the various factors driving IEEE 802.11b access points through extensive simulations and thereafter develops an optim

Optimization of Codec Parameters to Reduce Packet Loss Over WLAN,ressing the issues related to codecs. In multirate WLANs, users can suffer transmission rate changes due to the link adaptation mechanism. This results in a variable capacity channel, which is unsuitable for hosting VoIP calls and can cause serious Quality of Service (QoS) degradation in all the act

Often buffers are used to store the received packets for a short time before playing them at equal spaced intervals to minimize jitter. Choosing optimum buffering time is essential for reducing the added end-to-end delay and number of discarded packets. In this chapter, some estab

OPNET Modeler 14.5.A has been used for carrying out extensive analysis for voice quality in terms of MOS and end-to-end delays. An algorithm has been proposed that utilizes the RTCP receiver reports to assess the network condition and select the optimum packet payload size. T
