Abstract: Broadband-Integrated Services Digital Network (B-ISDN) is capable of supporting the transmission of multimedia applications such as data, voice and images concurrently, because it uses Asynchronous Transfer Mode (ATM) as the basis and ATM is a high-bandwidth, low-delay, connection-oriented cell switching and multiplexing technology. Traffic of different applications has different traf...

Center for Wireless Communications, University of California San Diego, 9500 Gilman Dr. La Jolla, CA 92093-0407, USA – fax: +1-619-534-2486 – e-mail: fzorzi,[email protected] Abstract— In this paper, we study the throughput and energy efficiency of TCP in the presence of correlated packet errors described by a Markov channel model. We consider a single connection and study the evolution of the ...

In the IEEE 802.11MAC layer protocol, the basic access method is the Distributed Coordination Function which is based on the CSMA/CA. In this paper, we investigate the performance of IEEE 802.11 DCF in the non-saturation condition. We assume that there is a fixed number n of competing stations and packet arrival process to a station is a poisson process. We model IEEE 802.11 DCF in non-saturati...

We used decision analysis techniques with Markov cohort modeling to examine the role of cancer antigen 125 (CA-125) in follow-up surveillance strategies among patients with advanced ovarian cancer. Utilities were derived from a societal perspective.Using quality-adjusted life years (QALYS) as the outcome variable, the value of CA-125 monitoring for asymptomatic women with ovarian cancer was fou...

This paper presents the analysis of a renewal input  finite buffer queue wherein the customers can decide either to  join the queue with a probability or balk. The service process is Markovian service process ($MSP$) governed  by an underlying $m$-state Markov chain. Employing the supplementary  variable and imbedded Markov chain techniques,   the steady-state system length distributions at pre...

The analysis and modeling of spatial temporal changes in land use can reveal changing urban patterns trends. In this paper, we introduce a linear transformation optimization Markov (LTOM) model that be exploited to estimate the state transition probability matrix use, building loosely coupled ANN-CA-LTOM for simulating predicting changes. advantages are it is flexible high expansibility; mainta...

This study establishes a target motion model and an observation model under the condition of colored noise by using the Kalman filter based on an improved IMM (interactive multiple model) for maneuvering target tracking. To improve the overall performance of IMM algorithm, we proposed to combine the CV (constant velocity) and CA (constant acceleration) models with the "current" statistical mode...
