Analyzing the Integration of WiMAX and Wi‐Fi Services: Bandwidth Sharing and Channel Collaboration

Abstract

Several emerging studies have focused on the pricing issue of bandwidth sharing between Wi-Fi and WiMAX networks; however, most either concentrate on the design of collaborated protocols or figure out the issue without the overall consideration of consumer preferences and contract design. In this study, we explore a wireless service market in which there are two wireless service providers operating Wi-Fi and WiMAX. One of the research dimensions given in this study is whether wireless service providers implement bandwidth sharing, while the other is whether they make decisions individually or jointly. By involving consumer preferences and a wholesale price contract in the present model, we find that bandwidth sharing would benefit a WiMAX service provider, yet a Wi-Fi service provider would make no significant savings under a wholesale price contract. In addition, the profit of a WiMAX service provider may increase with Wi-Fi coverage when bandwidth sharing has been implemented but decrease with Wi-Fi coverage when both wireless services operate without bandwidth sharing. Furthermore, the WiMAX service provider allocates more capacity when the average usage rate increases, but lowers the expenditure of capacity when the average usage rate is too high.

Analyzing game-streaming services in two-sided markets: Direct selling and cloud alliance models

“…In this way, the ISP's profit function π C can be written as In Equation ( 5), the ISP needs to fit the requirement EW≤d by expanding its IT capacity (i.e., service rate μ). Thus, following prior studies [41,42] , we solve EW=d to yield the ISP's minimal capacity cost cμ, where μ=βn (2,B) +1⁄d. By using this approach, the ISP's objective function can be rewritten as Next, the benefit of VM technology is prescribed in the following proposition.…”

Push or Pull? Design of Content Delivery Systems

“…The content provider has two major functions—generating content and delivering content. In the content generation stage , new content is generated according to a Poisson process with rate λ. Poisson processes have been widely used in similar contexts such as the transmission of data packets through the internet (Cheng, Bandyopadhyay, & Guo, ; Guo, Cheng, & Bandyopadhyay, ) and the arrival of subscribers on the WiMAX network (Li & Jhang‐Li, ). Furthermore, the content generation process satisfies the basic properties of Poisson processes (Kao, ): In a small time interval, the probability of generating more than two pieces of new information is negligible and the probability of generating one piece of new information is rate λ times the length of the interval.…”
