Comparative Study Of Congestion Control Techniques In High Speed Networks

Congestion in network occurs due to exceed in aggregate demand as compared to the accessible capacity of the resources. Network congestion will increase as network speed increases and new effective congestion control methods are needed, especially to handle bursty traffic of todays very high speed networks. Since late 90s numerous schemes i.e. [1]...[10] etc. have been proposed. This paper concentrates on comparative study of the different congestion control schemes based on some key performance metrics. An effort has been made to judge the performance of Maximum Entropy (ME) based solution for a steady state GE/GE/1/N censored queues with partial buffer sharing scheme against these key performance metrics.Comment: 10 pages IEEE format, International Journal of Computer Science and Information Security, IJCSIS November 2009, ISSN 1947 5500, http://sites.google.com/site/ijcsis

A Comparative Study on Performance Evaluation of Intrusion Detection System through Feature Reduction for High Speed Networks

Abstract- The rapid growth in the usage of the internet had led to many serious security issues in the network The intrusion detection system IDS is one of the sophisticated defensive systems used to detect the malicious activities happening in the network services across the world Hence more advanced IDS are been developed in past few years To improve the performance of the IDS the system has to be trained effectively to increase the efficiency and decrease the false alarm rate To train the system the attributes selection plays the major role This paper evaluates and compares the performance of the intrusion detection systems for different feature reduction techniques in high speed network

Comparative Performance Simulation of DSDV AODV and DSR MANET Protocols in NS2

Mobile Ad hoc Networks (MANET) are self-configured and infrastructure less networks with autonomous mobile nodes. Due to the high flexibility, these kind of networks are heavily used in rescue operations, military missions etc. Many routing protocols for this kind of networks exist. This article presents a comparative and quantitative performance study of DSDV, AODV and DSR routing protocols using different simulation models in NS2. Performance metrics like PDR, E2E Delay and Throughput are analyzed under varying network, traffic and mobility parameters like number of nodes, traffic flows, mobility speed and pause time. Results show that AODV outperforms DSDV and DSR in all the performance metrics. DSDV performs better than DSR in terms of PDR and E2E delay. DSR gives 20-30 higher Throughput than DSDV. Performance metrics are highly influenced by network topology parameters like number of nodes and number of traffic flow connections. Mobility parameters like speed and pause time have slight impact on performance

Multiple Access Techniques for VLC in Large Space Indoor Scenarios: A Comparative Study

The growing demand for high speed indoor wireless connectivity is among the driving forces for data transmission based on visible-light communications (VLC). For relatively large-space indoor scenarios, the development of appropriate spectrally-efficient multiple-access (MA) techniques enables efficient handling of multiple users, in particular, in dealing with the limited modulation bandwidth of the light-emitting diodes. In this paper, we present a comparative study between different MA techniques proposed in the recent literature for VLC networks. The most appropriate schemes for large-scale network deployments are further investigated in different scenarios to contrast their performance in terms of the achievable throughput

Jaringan Sensor Nirkabel: Studi dan Evaluasi Kinerja LoRa Transmitter dan Long Range Radio Frekuensi (RF) Pada Luar Ruang

Transmitters are the backbone of communication on wireless sensor networks. Most transmitters use ism band frequencies so the communication range is limited to 100 m. Some types of transmitters that have long-distance communication capabilities are nRF24 1 km and LoRa. The paper reports a comparative study between nRF24 1 km and LoRa in data communication, power consumption and resistance to obstacles. The results showed that LoRa has a range capability of 1.6 km and nRF24 has a delivery capability of 1 km. The 1 km NRF24 is more suitable for long-distance communication that requires high speed and is also resistant to non-line of sight obstacles

Analysis of LTE based an Antenna Design for 5G Communications

As the world progresses towards the next generation of communications networks, new technological solutions, architectures and standards are urgently required. This evolution of communications networks will facilitate numerous convincing business and consumer applications and speed up large investments in network infrastructure, appliances and devices. Wireless technologies of the last generation, 5G networks, promise an era of all-round, secure and powerful radio network. The use of 5G technology extends beyond traditional telecoms, and includes extremely low latencies, high energy efficiency or comprehensive Gbps. This paper also accurately includes 5G requirements and antenna categorization accompanied by a comparative study of various antenna designs. The various researchers have previously suggested several 5G antenna designs, but an exhaustive examination using their performance improvement system of the various types of 5G antenna has not yet been completed. We thus tried to examine the various types of 5G antenna design, their mechanisms for improving performance, comparisons and possible worldwide breakthroughs

The review of heterogeneous design frameworks/Platforms for digital systems embedded in FPGAs and SoCs

Systems-on-a-chip integrate specialized modules to provide well-defined functionality. In order to guarantee its efficiency, designersare careful to choose high-level electronic components. In particular,FPGAs (field-programmable gate array) have demonstrated theirability to meet the requirements of emerging technology. However,traditional design methods cannot keep up with the speed andefficiency imposed by the embedded systems industry, so severalframeworks have been developed to simplify the design process of anelectronic system, from its modeling to its physical implementation.This paper illustrates some of them and presents a comparative studybetween them. Indeed, we have selected design methods of SoC(ESP4ML and HLS4ML, OpenESP, LiteX, RubyRTL, PyMTL,SysPy, PyRTL, DSSoC) and NoC networks on OCN chip (PyOCN)and in general on FPGA (PRGA, OpenFPGA, AnyHLS, PYNQ, andPyLog).The objective of this article is to analyze each tool at several levelsand to discuss the benefit of each in the scientific community. Wewill analyze several aspects constituting the architecture and thestructure of the platforms to make a comparative study of thehardware and software design flows of digital systems.
