In this paper, a heterogeneous communication system capable of delivering 5G/sub-terahertz signal carriers over an arbitrary long fiber and separated transmission links is presented by employing direct detection, multiplexing techniques, advanced digital processing. experiment, the 3.5 GHz 28.5 carrier frequencies, representing 5G links, deliver 4 Gb/s 16-QAM OFDM signals to separate user ends ...

In reality networks may have random property, small-world property and scale-free property, so in this paper we introduce the heterogeneous network model. We construct the heterogeneous network based on ER random network, WS small-world network and BA scale-free network. Then we use the random rules to interconnect the three sub networks that generate the heterogeneous network. By analyzing the...

Network embedding is an effective way to realize the quantitative analysis of large-scale networks. However, mainstream network models are limited by manually pre-set metapaths, which leads unstable performance model. At same time, information from homogeneous neighbors mostly focused in encoding target node, while ignoring role heterogeneous node embedding. This paper proposes a new model, HeM...

A study on the performance of TCP Vegas versus different TCP variants in homogeneous and heterogeneous wired networks are performed via simulation experiment using network simulator (ns-2). This performance evaluation prepared a comparison medium for the performance evaluation of enhanced-TCP Vegas in wired network and for wireless network. In homogeneous network, the performance of TCP Tahoe, ...

Wide area computer networks have become a basic part of today's computing infrastructure. These networks connect a variety of machines, presenting an enormous computing resource. In this project we focus on developing methods and tools which allow a programmer to tap into this resource. In this paper we describe PVM and HeNCE, tools and methodology under development that assists a programmer in...

The Parallel Virtual Machine (PVM), an integrated framework for heterogeneous network computing, lets scientists exploit collections of networked machines when carrying out complex scientiic computations. Under PVM, a user-deened grouping of serial, parallel, and vector computers appears as one large distributed-memory machine. Connguring a personal parallel virtual computer involves simply lis...

The present paper analyzes a network formation problem, mainly based on the framework presented in [Bala-Goyal 2000]. We depart from their assumptions in two crucial aspects. On one hand, we assume that connecting to an agent pays off not only for the number of connections that the agent can provide but also for her intrinsic value. Since the values of the agents (which represent the amounts of...
