How to scale to 256 processors and beyond

On the advice of fellow ZDNet blogger Mary-Jo Foley I recently watched a video interview with Mark Russinovich. She wrote: "Given I’m not a programmer and am trying to channel a very technical Russinovich, it’s probably worth checking out the Channel 9 video interview of him yourself if you care...

Contention-Aware Analysis of Routing Schemes for Mobile Opportunistic Networks

A large body of work has theoretically analyzed the performance of routing schemes for mobile opportunistic networks. But a vast majority of these prior studies have ignored wireless contention. This paper analyzes the performance of routing schemes under contention. To model contention the paper uses the recently-proposed analytical framework which...

Comparison of Modified Dual Queue and EDCA for VoIP Over IEEE 802.11 WLAN

The popular IEEE 802.11 WLAN today does not provide any Quality-of-Service QoS because of its contention-based channel access nature of the Medium Access Control MAC. Therefore, this paper proposes a simple software upgrade-based solution, called a dual queue scheme, to provide QoS to real-time services such as Voice-over-IP VoIP in...

Bandwidth Contention With Backpressure Scheme Over VDSL Network

Bandwidth Contention in VDSL network occurs whenever the demand of bandwidth consumption exceeds the network capacity per se, causing lower throughputs and higher traversal time delays. If the bandwidth contention cannot be ease nor appropriately controlled, some sessions transported by the network may not meet their Quality-of-Services QoS. An existing...

Understanding 802.11e Contention-Based Prioritization Mechanisms and Their Coexistence With Legacy 802.11 Stations

The IEEE 802.11e task group has reached a stable consensus on two basic contention-based priority mechanisms to promote for standardization: usage of different arbitration interframe spaces and usage of different minimum/maximum contention windows. The goal of this paper is to provide a thorough understanding of the principles behind their operation....
