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...

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 ...

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...
