With wireless network virtualization, Mobile Virtual Network Operators (MVNOs) can develop new services on a low-cost platform by leasing virtual resources from mobile network owners. In this paper, we investigate a two-stage spectrum leasing framework, where an MVNO acquires radio spectrum through both advance reservation and on-demand request. To maximize its surplus, the MVNO jointly optimiz...

Earlier models of quality differentiation showed that the qualities, of differentiated products, were lowered below efficient levels. Recently, qualities were shown to be enhanced, not degraded, in some cases. This paper presents a complete characterization of quality choices under vertical product differentiation by incorporating and refining assumptions on consumer preferences and production ...

In order to optimize the operation of the RSVPv2 protocol in mobile infra-structured networks this paper proposes a set of extensions. The proposed extensions are: employment of the reservation message to quickly create reservation states after a handoff is performed; utilization of teardown message in order to explicitly remove the reservation states from the old path; extension of the mobile ...

The Redistributive Effects of Political Reservation for Minorities: Evidence from India We examine the impact of political reservation for disadvantaged minority groups on poverty. To address the concern that political reservation is endogenous in the relationship between poverty and reservation, we take advantage of the state-time variation in reservation in state legislative assemblies in Ind...

Most routing and wavelength assignment (RWA) algorithms for all-optical networks do not consider the potential problem of wavelength reservation confliction, which can happen even if the network is only lightly loaded. In this paper, we propose a new reservation protocol MBR (Markov-based backward reservation) based on Markov modeling of the optical links. Our simulations show that this new pro...

We investigate how co-existence of two types of customers, price-takers and bargainers, influences the pricing decisions in a supply chain. We consider a stylized supply chain which includes one manufacturer and one retailer, and we characterize the optimal prices of the retailer and the manufacturer. We further discuss the effects of the fraction of the bargainers in the customer population an...
