Abstract
Nowadays, hotspots are being largely deployed by WISPs (Wireless Internet Service Providers) as a ubiquitous means of offering Internet access to their customers. However, sparse of spectrum and costly infrastructure, it requires more flexible bandwidth management than before. In order to alleviate the burden of cost incurred by service providers, this thesis introduces a simple concept of bandwidth sharing in a wireless environment. As in the case of MVNO, wireless networks will also develop “virtual operator” to run their business. The facility band operator can unite all of its virtual operators to share bandwidth by different market segment. It proposes a dynamic programming algorithm to obtain the optimal solution by forecasting bandwidth demand in advance. The research will simulate the three virtual operators’ behavior in an IEEE 802.11g environment. These simulations are conducted in different market segments and analyze the performance of the bandwidth sharing algorithm. The results show that the bandwidth sharing model for virtual network operators can not only provide higher bandwidth utilization and QoS but also earn more profit for all virtual operators. In addition, the model can help operators to alleviate the unexpected increase in bandwidth demand. As a conclusion, the model provides an optimal bandwidth sharing algorithm and the rental management procedure for operators in the future wireless environment.
