Heterogeneous Networks of Workstations

2004
Parallel systems built from commodity CPUs and networking devices (Networks of Workstations or NoW) are easily and economically constructed. Rapid technological change means that as elements are added to or replaced in such a system, it will inevitably become heterogeneous.

On the Potential of Heterogeneous Networks

2006
Many research work is going on in the domain of pure ad-hoc networking and even more issues are raised due to the missing central infrastructure to properly manage resources, guarantee fairness, and provide security features. On the other hand lot of research effort is spent to increase the performance of infrastructure-based access networks to cope ...

Coverage In Heterogeneous Sensor Networks

2006 4th International Symposium on Modeling and Optimization in Mobile, Ad Hoc and Wireless Networks, 2006
In this paper we study the problem of coverage in heterogeneous planar sensor networks. Coverage as a performance metric, quantifies the quality of monitoring provided by the sensor network. We formulate the problem of coverage as a set intersection problem arising in Integral Geometry, and derive analytical expressions for stochastic coverage.

CONTAGION IN HETEROGENEOUS FINANCIAL NETWORKS

Advances in Complex Systems, 2016
In this paper, we use the financial network contagion model of Gai P. and Kapadia S. [Contagion in financial networks, Proc. R. Soc. A 466 (2010) 2401–2423] to investigatethe interaction of several types of heterogeneity found in real world banking systems.

Modularity for heterogeneous networks

Proceedings of the 21st ACM conference on Hypertext and hypermedia, 2010
Online social media such as delicious and digg are represented as tripartite networks whose vertices are users, tags, and resources. Detecting communities from such tripartite networks is practically important. Modularity is often used as the criteria for evaluating the goodness of network divisions into communities.

Online caching in heterogeneous networks

2017 IEEE International Conference on Communications (ICC), 2017
In this paper we propose a novel online caching method to perform the update phase in a distributed caching system, with a natural application to heterogeneous scenarios with cache-equipped small-cell base stations. We investigate the performance of our scheme, showing in particular that it results in a significant reduction of backhaul load, to the ...

Dynamics of heterogeneous polymer networks

Physical Review E, 1994
This paper discusses the effect of heterogeneities in cross-link density on network dynamics. The dynamic effects of such networks are studied in two limits, i.e., at short times and at long times. It is shown that heterogeneities in cross-link density alter the chain dynamics strongly.

Quantifying network heterogeneity

Physical Review E, 2010
Despite degree distributions give some insights about how heterogeneous a network is, they fail in giving a unique quantitative characterization of network heterogeneity. This is particularly the case when several different distributions fit for the same network, when the number of data points is very scarce due to network size, or when we have to ...

Message Multicasting in Heterogeneous Networks

SIAM Journal on Computing, 2000
Summary: In heterogeneous networks, sending messages may incur different delays on different links, and each node may have a different switching time between messages. The well-studied telephone model is obtained when all link delays and switching times are equal to one unit.

Modeling heterogeneous network interference

2012 Information Theory and Applications Workshop, 2012
Cellular systems are becoming more heterogeneous with the introduction of low power nodes including femtocells, relays, and distributed antennas. Unfortunately, the resulting interference environment is also becoming more complex, making evaluation of different communication strategies for cellular systems more challenging in both analysis and ...
