In this paper, we propose a way of achieving optimally in radio resource management (RRM) for heterogeneous networks. We consider a micro or femto cell with two co-localized radio access technologies (RAT), e.g. WLAN and HSDPA. RAT are mainly characterized by the data rates they offer at a given distance of the access point. Dual-technology mobile stations (MS) are initiating downlink sessions in...
Virtual networks and service overlay networks lease bandwidth from Internet autonomous systems to offer end to end quality of service at competitive costs. In this paper, we propose a novel network resource management approach, based on an economic model, which allows continuous optimizing of the network profit, while keeping acceptable grade of service. The proposal integrates leased link capacity...
Military wireless networks suffer from privacy and performance concerns due to their shared radio medium and off-the-shelf products. Therefore, robust and efficient security management is essential in these networks, especially for the transmission of sensitive data. However, security solutions based on static-configuration paradigm do not adapt to changing network conditions, such as variations in...
