WWIC - Analyzing the Performance of Data Users in Packet Switched Wireless Systems with Prioritized Voice Traffic
Lecture Notes in Computer Science, 2004Co-Authors: Roshni Srinivasan, John S. BarasAbstract:The integration of Wireless Telephony and data services in 3G and 4G Wireless systems that use packet-switched air interfaces poses new challenges in the management of network resources. Although highly compressed voice traffic is given priority over data traffic, scheduling algorithms which exploit multiuser diversity have been shown to significantly improve the data throughput. In this paper, we quantify the effect of prioritized voice traffic on the performance of data users in the system using a mix of analysis and simulation. We analytically characterize the scheduled rate, delay and packet service times for data in the presence of prioritized voice traffic by using a general scheduling metric that incorporates a measure of the user’s channel quality in addition to a delay constraint. The results provide important tools for cellular network operators to evaluate system performance and provision resources for traffic with varying Quality of Service (QoS) requirements.

The development of Wireless telecommunications and local governments' policy responses: The U.S. case
Government Information Quarterly, 2007Co-Authors: Seongcheol KimAbstract:Abstract The increasing popularity of Wireless Telephony creates a new set of challenges for local governments as the need for corresponding Wireless facilities occurs in direct proportion to this growth. In particular, the influx of new Wireless telecommunications providers poses significant challenges for local governments as they carry out their traditional zoning and land use functions. Considering local governments' concerns over the challenges posed by the proliferation of Wireless towers, this paper attempts to give a policy insight on the issue of “Wireless facilities siting”. This research suggests that the role of local governments should be to balance conflicting interests and that appropriate and timely presentation of Wireless telecommunication initiatives by local governments are essential to opening a new era of Wireless telecommunication.

voice compression systems for Wireless Telephony
International Conference of the Chilean Computer Science Society, 2001Co-Authors: J Bustos, A BassiAbstract:This paper presents a comparative study between three voice compression systems for Wireless Telephony: CELP (code excited linear prediction), VSELP (vector sum excited linear prediction) and GSM 06. 10 (Global Standard for Mobile communications), and one system based on artificial neural networks (ANNs). The main result is that the system based on ANNs exceeds the best current performance standard (CELP). However, its speaker dependency hinders its potential standardization.

COMPSAC (1) - Plenary Panel Title: Software for the Mobile Inter
31st Annual International Computer Software and Applications Conference - Vol. 1- (COMPSAC 2007), 2007Co-Authors: Stephen ChenAbstract:The Internet was a disruptive force. Innovative entrepreneurs created a new industry which has added significantly to the world's economies and spearheaded a revolution in information creation and distribution unparalleled in modern history. Similarly, the advent of Wireless telecommunications has been a major disruptive force to the traditional wireline industry. By the beginning of the 21st centry, the amount of Wireless Telephony traffic had exceeded that carried by wireline. Moreover, the number of people in the world who now have access to telecommunications has grown exponentially. In this panel, we explore the implications of the coming together of these two disruptive forces and focus on the role of software relative to this phenomenon.
