Migrating users in a wireless multicast network may need to recover lost data during handoffs before they can merge into the respective multicast groups in the new cell. The multicast groups in packet switched wireless networks typically share resources on a statistical multiplexed basis. To minimize impact on other users, we allow part of a multicast group’s assigned bandwidth to be shared by ...

Recently, several wireless scheduling algorithms have been proposed. It is important to evaluate their performance to establish the QoS provision capabilities of wireless networks. In this paper, we define a Wired-Fair scheduling scheme which is fair and but not channel-efficient, a ChannelEfficient scheduling scheme which is not fair and a WirelessFair scheduling scheme that is both channel-ef...

One-third of the world's reef-building corals are facing heightened extinction risk from climate change and other anthropogenic impacts. Previous studies have shown that such threats are not distributed randomly across the coral tree of life, and future extinctions have the potential to disproportionately reduce the phylogenetic diversity of this group on a global scale. However, the impact of ...

CSMA/ECA is a contention protocol that makes it possible to construct a collision-free schedule by using a deterministic backoff after successful transmissions. In this paper, we further enhance the CSMA/ECA protocol with two properties that allows to fairly accommodate a large number of contenders in a collision-free schedule. The first property, called hysteresis, instructs the contenders not...

explaining dividend policy has been one of the most difficult challenges facing financial economists. despite decades of study, we have yet to completely understand the factors that influence dividend policy and the manner in which these factors interact.the aim of this paper is to examine the relation between dividend policy and share price volatility in tehran stock exchange (tse). the analys...
