Caching-Aware Intelligent Handover Strategy for LEO Satellite Networks

open access: yesRemote Sensing, 2021
Recently, many Low Earth Orbit (LEO) satellite networks are being implemented to provide seamless communication services for global users. Since the high mobility of LEO satellites, handover strategy has become one of the most important topics for LEO ...

Modelling of CDMA systems

open access: yesJournal of Telecommunications and Information Technology, 2001
This paper describes a model of a system with wideband CDMA that is a proposal of user access for future UMTS. This model has been implemented using OPNET tool.

FURTHER OBSERVATIONS ON DEPOLARIZING NEUROMUSCULAR BLOCK: THE SO-CALLED PHASE II BLOCK

open access: yesBritish Journal of Anaesthesia, 1974
The biphasic depression of muscle contractions induced by succinylcholine (Sch) and decamethonium (C 10 ) in rat diaphragms at 32 °C was investigated. The type of depression induced by these muscle relaxants was dependent on their speed of administration and the experimental conditions.

Channel assigning scheme study in LEO constellation communication system combining handover reserving strategy and new call queuing

open access: yesTongxin xuebao, 2006
A channel assigning scheme which was adapted to LEO constellation communication system was proposed. The scheme provided reserved channel for handover call to reduce blocking probability of handoff call.Meanwhile, new call queuing strategy was adopted to

An Erlang multirate loss model supporting elastic traffic under the threshold policy

open access: yes, 2015
In this paper, we propose a multirate teletraffic loss model of a single link with certain bandwidth capacity that accommodates Poisson arriving calls, which can tolerate bandwidth compression (elastic traffic), under the threshold policy.

CAC DPLB MCN: A Distributed Load Balancing Scheme in Multimedia Mobile Cellular Networks

open access: yesFoundations of Computing and Decision Sciences, 2016
The problem of non-uniform traffic demand in different cells of a cellular network may lead to a gross imbalance in the system performance. Thus, the users in hot cells may suffer from low throughput. In this paper, an effective and simple load balancing

Blocking API calls for security

open access: yes, 2020
The typical user feels comfortable with just having anti-virus software running on their computers. This solution works well if viruses are known and the virus databases are updated frequently. The virus writing community has responded by writing software that mutates the viruses so that these viruses are undetectable to the anti-virus software ...

Dynamic path restoration for new call blocking versus handoff call blocking in heterogeneous network using buffers for QoS [PDF]

open access: yesInternational Journal of Advanced Computer Science and Applications, 2010
An Ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing heterogeneous network infrastructure or centralized administration. Routing protocols used inside ad hoc networks must be prepared to automatically adjust to an environment that can vary between the extremes of high ...

Modeling and simulation of call centers.

open access: yes, 2006
In this review, we introduce key notions and describe the decision problems commonly encountered in call center management. Main themes are the central role of uncertainty throughout the decision hierarchy and the many operational complexities and ...

Congestion probabilities in CDMA-based networks supporting batched Poisson traffic

open access: yes, 2014
We propose a new multirate teletraffic loss model for the calculation of time and call\ud congestion probabilities in CDMA-based networks that accommodate calls of different serviceclasses\ud whose arrival follows a batched Poisson process. The latter is
