Throughput and Capacity of MIMO WiMAX

The work in this paper presents physical layer throughput measurement results of a WiMAX link implemented according to IEEE 802.16-2004. The measurements were carried out in an alpine and an urban scenario using the Vienna MIMO Testbed. The paper compares the measured throughput to three different theoretical bounds: the channel...

New Wi-Fi chipsets promise up to 2x throughput of current 802.11n devices

A couple of weeks ago I did a post on the Home Theater blog about Celeno Communications' wireless chip that the company claims can support four different HD streams simultaneously. Now another company has announced its own Wi-Fi technology that promises significant performance improvement over the 802.11n spec. Quantenna's QHS...

Gnort: High Performance Network Intrusion Detection Using Graphics Processors

The constant increase in link speeds and number of threats poses challenges to Network Intrusion Detection Systems NIDS, which must cope with higher traffic throughput and perform even more complex per-packet processing. This paper presents an intrusion detection system based on the Snort open-source NIDS that exploits the underutilized computational...

CDMA Channel Parameters Maximizing TCP Throughput

A single TCP session traversing a wireless channel is considered in this paper, with a constant SIgnal to Noise Ratio SINR at the receiver. The problem of determining the optimal transmission energy per bit is considered, to maximize TCP throughput. Specifically, in the case where direct sequence spread spectrum modulation...

Optimum Number of RLC Retransmissions for Best TCP Performance in UTRAN

As far as transfer reliability is concerned, the wireless segment of UTRAN is the weakest part of an Internet session. To overcome this imperfection, the RLC protocol features a link-level retransmission mechanism. This paper shows by analytical means and computer simulations that for a given Block Error Rate BLER, the...

Internet Security Trends for 2007: A Report on Spam, Viruses and Spyware

At the highest level, 2006 saw an increase in both the sophistication and the volume of Internet security threats. Spammers created triple the volume of image-based spam. This threat has a dual effect on infrastructure: incoming mail throughput has increased four times faster than Moore's law (the typical increase in...

802.11 Wireless Networks - A Peek Ahead at 802.11n: MIMO OFDM

802.11 Task Group N TGn has an interesting goal. Most IEEE task groups focus on increasing the peak throughput, making data fly as fast as possible during the time it is being transmitted. TGn's goal is to achieve 100 Mbps net throughput, after subtracting all the overhead for protocol management...
