The Internet has revolutionized the telecommunication systems by supporting new
applications and services. Voice over Internet Protocol (VoIP) is one of the most prominent …

In this paper we examine the feasibility of semi-persistent scheduling (SPS) for voice over IP
(VoIP) by random access and evaluate its performance in terms of throughput of random …

In recent literature on traffic scheduling, the combination of the two-dimensional discrete-
time Markov chain (DTMC) and the Markov modulated Poisson process (MMPP) is used to …

Using services on mobile devices for time-and safety-critical applications, like abnormal
situation or disaster management, requires a high availability and reliability of the services …

A new algorithm is proposed for wireless voice over IP (VoIP) codecs that allocates radio
resources in consideration of the variations in packet size and packet-generation period …

提出一种基于LTE 系统的VoIP 服务的自适应上行调度算法, 该算法采用自适应多速率语音编码
器, 利用传统MAC 通用报头中的2 个比特将语音编码的模式告知eNB, eNB 根据UE …

This paper has designed a cross-layer framework for voice over Internet protocol (VoIP)
services in IEEE 802.16 systems. It uses the application session information of the session …

Abstract Information always comes with security and risk problems. There is the saying that,"
The tall tree catches much wind," and the risks from cloud services will absolutely be more …

A key component of the Internet of things (IoT) ecosystem is wide-area network connectivity,
for which cellular network technologies are a promising option through their support of …

With the advent of 4G mobile communication system the traffic of wired and wireless network
becomes voice/videodata integrated service. In this paper traffic model of Markov Modulated …
