In this paper we propose a framework for a simple resource reservation protocol for multicast communications in the Internet. In contrast to RSVP, where heavy setup mechanisms are used, our protocol is traffic driven and does not use special messages for resource reservation, refresh or release. The reservation session is managed by the flow data packets themselves. Our protocol is suitable for...

Multimedia and real-time applications require bandwidth guarantees, which may be achieved by resource reservation. However, resource reservation in ad-hoc networks is a very challenging task due to the instability of radio channels, node mobility and lack of coordination between mobile nodes. Proposed reservation MAC protocols like CATA, FPRP, R-CSMA and SRMA/PA have limitations and are suitabl...

Revisiting Inter-Industry Wage Differentials and the Gender Wage Gap: An Identification Problem We propose a measure of the industrial gender wage gap which is free from an identification problem by using inter-industry wage differentials, or industrial wage premia. We draw on a recent literature showing that a normalized regression equation can be used to resolve the identification problem in ...

To satisfy both the bandwidth efficiency of low-speed mobile hosts (MHs) and seamless handoff of high-speed MHs in cellular networks, this paper proposes a reservation scheme which exploits a dynamic two-tier cell structure and the handoff probability. The dynamic two-tier cell structure determines the reservation and non-reservation zones according to the speed of MHs. The handoff probability ...

What Do Labor Market Institutions Do? The past couple of decades have seen a huge increase in research on various labor market institutions. This paper offers a brief overview and discussion of research on the labor market impacts of minimum wages (MW), unemployment insurance (UI), and employment protection legislation (EPL). It is argued that research on UI is largely a success story, involvin...

Centralized wage-setting institutions are considered to be more effective at reducing wage inequality. In this paper, I offer an expansive cross-national analysis of the effects of recent liberalization in wage-setting institutions on wage inequality in the OECD, taking into special consideration the effects of EU and EMU membership. A qualitative comparison of liberalization occurring within E...
