Satellite comms to bridge digital divide?
News The UN agency for information and communications issues is looking to the heavens to bridge the digital divide. When it comes to the global digital divide, the ITU hopes satellite comms will play a vital role in "connecting the unconnected" - and... [28 Feb 2008]
A Systematic Analysis of High Throughput TCP in Real Network Environments
White Paper It is this poor scalability of standard TCP that results in network throughput that is well below the network capacity even on un-congested links. Within the last few years, computer scientists and intensive network users have discovered that... [14 Jan 2008]
Extended Abstract: Understanding the Effect of Access Point Density on Wireless LAN Performance
White Paper With increasing penetration of WiFi into residential areas and usage in ad hoc conference settings, chaotic un-planned deployments are becoming the norm rather than an exception. This paper presents a systematic experimental study of the effect of... [05 Dec 2007]
Feature Preparation in Text Categorization
White Paper The comparison of these classifiers shows that stemmed or un-stemmed single words as features give better classifier performance compared with other types of features, and LOG(tf)IDF weight as feature weight gives better classifier performance... [06 Nov 2007]
Understanding the Behavior of TCP for Realtime CBR Workloads
White Paper Traditionally, TCP has been considered un-desirable for real-time CBR workloads. This paper examines the feasibility of sending real-time CBR workloads over TCP. This is motivated by the friendliness of NATs and firewalls towards TCP as opposed to... [06 Nov 2007]
