Stability of Multi-Class Queueing Systems with State-dependent Service Rates

by Matthieu Jonckheere, Sem Borst , 2006
"... We examine the stability of multi-class queueing systems with the special feature that the service rates of the various classes depend on the number of users present of each of the classes. As a result, the various classes interact in a complex dynamic fashion. Such models arise in several contexts, ..."

Mathematical Methods in Operations Research 2005 Special issue in honor of Arie Hordijk Controlling an oscillating Jackson-type network having state-dependent service rates

by Arnon Arazi, Eshel Ben-jacob, Uri Yechiali
"... Abstract We consider a Jackson-type network comprised of 2 queues having state-dependent service rates, in which the queue lengths evolve periodically, exhibiting noisy cycles. To reduce this noise a certain heuristic, utilizing regions in the phase space in which the system behaves almost determini ..."

Extremal Properties of the Shortest Non-Full Queue and the Longest Non-Full Queue Policies in Finite Capacity Systems with State-Dependent Service Rates

by P. D. Sparaggis, D. Towsley, C. G. Cassandras , 1991
"... We consider the problem of routing jobs to parallel queues with identical exponential servers and unequal finite buffer capacities. Service rates are state-dependent and non-decreasing with respect to queue lengths. We establish the extremal properties of the Shortest Non-Full Queue (SNQ) and the Lo ..."

Financial Dependence and Growth

by Raghuram G. Rajan, Luigi Zingales - American Economic Review , 1998
"... This paper examines whether nancial development facilitates economic growth by scrutinizing one rationale for such a relationship; that nancial development reduces the costs of external nance to rms. Speci cally, we ask whether industrial sectors that are relatively more in need of external nance de ..."

as far back as Joseph A. Schumpeter (1911), emphasizes the positive in uence of the development of a country's nancial sector on the level and the rate of growth of its per capita income. The argument essentially is that the services the nancial sector provides { of reallocating capital

A Rate-Adaptive MAC Protocol for Multi-Hop Wireless Networks

by Gavin Holland, Nitin H. Vaidya, Paramvir Bahl , 2001
"... Wireless local area networks (W-LANs) have become increasingly popular due to the recent availability of affordable devices that are capable of communicating at high data rates. These high rates are possible, in part, through new modulation schemes that are optimized for the channel conditions bring ..."
Abstract - Cited by 484 (5 self) - Add to MetaCart
bringing about a dramatic increase in bandwidth efficiency. Since the choice of which modulation scheme to use depends on the current state of the transmission channel, newer wireless devices often support multiple modulation schemes, and hence multiple data rates, with mechanisms to switch between them

An Architecture for Wide-Area Multicast Routing

by Stephen Deering , Deborah Estrin , Dino Farinacci , Van Jacobson , Ching-gung Liu, Liming Wei
"... Existing multicast routing mechanisms were intended for use within regions where a group is widely represented or bandwidth is universally plentiful. When group members, and senders to those group members, are distributed sparsely across a wide area, these schemes are not efficient; data packets or ..."

is measured in terms of the state, control message processing, and data packet processing, required across the entire network in order to deliver data packets to the members of the group. Our Protocol Independent Multicast (PIM) architecture: (a) maintains the traditional IP multicast service model

An inventory for measuring depression

A message ferrying approach for data delivery in sparse mobile ad hoc networks

by Wenrui Zhao, Mostafa Ammar, Ellen Zegura - In Proc. of ACM Mobihoc , 2004
"... Mobile Ad Hoc Networks (MANETs) provide rapidly deployable and self-configuring network capacity required in many critical applications, e.g., battlefields, disaster relief and wide area sensing. In this paper we study the problem of efficient data delivery in sparse MANETs where network partitions ..."

can last for a significant period. Previous approaches rely on the use of either long range communication which leads to rapid draining of nodes ’ limited batteries, or existing node mobility which results in low data delivery rates and large delays. In this paper, we describe a Message Ferrying (MF
