The Tuple Channel coordination model
Proceedings of PDSE '97: 2nd International Workshop on Software Engineering for Parallel and Distributed Systems, 2002We present a new coordination model and a small set of programming notations for distributed programming that can be integrated into very different programming languages (imperative, declarative or object oriented). Both together, allow distributed programs to be developed in a compositional way, by assembling different independent pieces of (possibly ...

Channel Modeling for V2V Communications
2006 Third Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services, 2006In this paper we describe results of a channel measurement campaign for modeling the V2V channel. After review of applications, potential frequency bands, and related work, we describe the measurements and results for delay spreads and multipath component fading amplitudes and correlations, made in multiple V2V environments.

Statistical modeling of the LMS channel
IEEE Transactions on Vehicular Technology, 2001In this paper, a statistical model for the land mobile satellite (LMS) channel is presented. The model is capable of describing both narrow- and wide-band conditions. The other relevant characteristic is that it can be used to study links with geostationary as well as nongeostationary satellites. The model is of the generative type, i.e., it is capable

Converting SIRCIM Indoor Channel Model into SNR-Based Channel Model
2005The event-driven network simulation platforms, e.g. NS2 and GloMoSim, adopt some general wireless channel propagation models providing the pathloss of the channel as well as the SNR of each received packet to estimate the BER. However, these SNR-based general channel models give more accurate results for outdoor environments than indoor.

Generative-Adversarial-Network-Based Wireless Channel Modeling: Challenges and Opportunities
IEEE Communications Magazine, 2019In modern wireless communication systems, wireless channel modeling has always been a fundamental task in system design and performance optimization. Traditional channel modeling methods, such as ray-tracing and geometry- based stochastic channel models,

On formal modeling of communication channels
IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies, 1989A formal semantics of a model for a communication channel is given. The model is the foundation of a simulation package which can be used for modeling of communication phenomena in distributed physical systems. The software system based on the model can be viewed as an emulator for LAN-type communication networks.

On tractable wireless channel models
Ninth IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (Cat. No.98TH8361), 2002We present techniques to capture the behavior of realistic channels with mathematically tractable models, We examine different state-space aggregation techniques to reduce a large number of states of Markov chain to a fewer number of states, The property of strong and weak lumpability is discussed and the stochastic bounding techniques are examined ...

A multipath model for the powerline channel
IEEE Transactions on Communications, 2002The development of powerline communication (PLC) systems for Internet, voice, and data services requires measurement-based models of the transfer characteristics of the mains network suitable for performance analysis by simulation. This paper presents an analytic model describing complex transfer functions of typical powerline networks using only a ...

Modeling wireless channel fading
IEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002We compare measured fading data with the popular Rayleigh model. Our results show that this model does not agree with the experimental data. As an alternative, we approximate the experimental data using autoregressive moving average (ARMA) models. To validate the models, we compare several characteristics of fading obtained analytically, by simulation,

Na(+)- and Ca2(+)-channel blockers behave as electron donors in reactions with excited dye radicals, while agonists of these channels behave as electron acceptors in the same reactions. The opposite redox characteristics of channel blockers and agonists may reflect their opposite action on the channels.
