Dynamic pricing has been used as an effective means to alleviate network congestion in mobile networks. It is potentially capable of gaining higher revenue over the fixed pricing scheme. However, the dynamic pricing scheme fails to provide user satisfaction since there is absolutely no guarantee that, during the time of congestion, users could get the… (More)
As wireless services have become increasingly integrated and their demand is mounting, Wi-Fi provides an appealing opportunity for the GSM/GPRS operators to enhance their data capability. By integrating both networks, operators are able to provide 3G-like services. However, both networks have different data rates and capacity, which makes pricing a… (More)
Dynamic pricing schemes in telecommunication networks were traditionally employed to create users' incentives in such a way that the overall utilization is improved and profits are maximized. However, such schemes create frustration to users, since there is no guarantee that they would get services at the anticipated prices. In this paper, we propose a… (More)
We propose an auction-based pricing scheme for admission in a GPRS network, that could enhance the GPRS data service. Important features of our approach are the partitioning of dedicated channels for enhanced data service and the employment of an auction mechanism based on revenue-maximizing auctions (optimal auctions).
In a wireless environment, the impairment of communication channels can affect significantly the performance of broadband wireless system. This paper presents an analytical model on the performance of a GSM/GPRS system with channel impairment. The model incorporates the interfering effects causing by the bit error rate of affected channels and the… (More)
