Introduction

Gunawardena, Subodha; Zhuang, Weihua

Pages: 1 –8

[The extensive growth of wireless networks over the recent years has increased the demand for the radio spectrum to a great extent. Static spectrum allocation regardless of its spatiotemporal usage has led to scarcity of the spectrum. As a result, fulfilling the spectrum requirements of emerging...

Voice Capacity Analysis

Gunawardena, Subodha; Zhuang, Weihua

Pages: 9 –40

[The voice and video streaming are the most common real-time wireless services in the modern day wireless networks [1]. The demand for video streaming is growing rapidly, and it is predicted to be the most common wireless service in the future [2]. As an upcoming networking approach, it is...

Service Response Time of Elastic Data Traffic

Gunawardena, Subodha; Zhuang, Weihua

Pages: 41 –69

[As we have discussed in Chap. 2, various studies on conversational and streaming type traffic flows over CRNs have been carried out over the recent years. So far, little attention is paid to the performance analysis of request-response type services such as web browsing over CRNs. This type of...

Service Response Time of Interactive Data Traffic

Gunawardena, Subodha; Zhuang, Weihua

Pages: 71 –85

[So far, we have discussed the mean response time of data sessions consisting of single file request (service request). However, in reality, very often each user (such as one browsing the web) places multiple service requests one after another before taking a break from browsing the web, and...

Conclusions and Future Directions

Gunawardena, Subodha; Zhuang, Weihua

Pages: 87 –91

[The objective of this Brief is to study the voice capacity of CRNs and the mean response time of elastic/interactive data traffic over the CRNs with different service processes. As there is an uncertainty in spectrum resource availability, rather than a strict delay requirement, a stochastic...
