A class of multi-carrier CDMA access methods for wide-bandwidth wireless channels
(2005)In this article we describe and evaluate a general class of synchronous multi-carrier CDMA methods. In the proposed methods each accessing user is encoded by a Hadamard sequence and a multi-carrier (MC) encoder. The ... -
Cross-layer DASH-based multipath video streaming over LTE and 802.11ac networks
(2021)Dynamic Adaptive Streaming over Http (DASH) -based video streaming applications are becoming increasingly prevalent over the mobile Internet. Many efforts have been made to optimize their performances. Multipath video ... -
Cross-network and cross-layer optimized video streaming over LTE and WCDMA downlink
(2016)Video services are proliferating over today's mobile Internet and efforts have been made to improve their performance. The cross-layer video streaming that jointly optimizes the parameters at different protocol layers is ... -
Distributed on-line schedule adaptation for balanced slot allocation in wireless ad hoc networks
(2004)We propose an algorithm for design and on the fly modification of the schedule of a wireless ad hoc network for provision of fair service guarantees under topological changes. The primary objective is to derive a distributed ... -
Distributed resource allocation algorithms for peer-to-peer networks
(2008)In peer-to-peer networks, each peer plays the role of client and server. As server, it receives content requests made by other peers and needs to decide on what basis and to what extent it will satisfy these requests by ... -
Dynamic viewing pattern exploitation in Peer-to-Peer Video-on-Demand
(2011)Unstructured BitTorrent-like Peer-to-Peer networks have been extensively studied as an important enabling technology for Video-on-Demand. While most studies maintain the pull-based nature of unstructured Peer-to-Peer ... -
End-to-end bandwidth guarantees through fair local spectrum share in wireless ad-hoc networks
(2003)Sharing the locally common spectrum among the links of the same vicinity is a fundamental problem in wire-less ad-hoc networks. Lately some scheduling approaches have been proposed that guarantee fair share of the bandwidth ... -
End-to-end bandwidth guarantees through fair local spectrum share in wireless ad-hoc networks
(2005)Sharing the common spectrum among the links in a vicinity is a fundamental problem in wireless ad-hoc networks. Lately, some scheduling approaches have been proposed that guarantee fair share of bandwidth among the links. ... -
Evolutionary fuzzy multi-objective routing for wireless mobile ad hoc networks
(2004)The complexity involved in implementing multi-objective routing in computer networks has led to many researchers exploring alternate solutions with the use of heuristic based techniques. The rationale underlying the use ... -
FIJI: Fighting implicit jamming in 802.11 WLANs
(2009)The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take ... -
i-WABA: An efficient wavelengths arrangement and bandwidth allocation WDMA protocol for passive optical intra-rack data center networks
(2022)In this article, we effectively handle the continuously growing traffic within data centers (DCs) and we focus on the intra-rack communication. We propose a passive optical intra-rack DC network (DCN) that uses a set of ... -
Layered multicast rate control based on lagrangian relaxation and dynamic programming
(2004)In this paper, we address the rate control problem for layered multicast traffic, with the objective of solving a generalized throughput/fairness objective. Our approach is based on a combination of lagrangian relaxation ... -
LB-Grid: An SSD efficient Grid File
(2019)Recent advances in non-volatile memory technology have led to the introduction of solid state drives (SSD). NVMe SSDs are the latest development in flash based solid state drives and they were designed as a means of low ... -
MEC-Assisted panoramic VR video streaming over millimeter wave mobile networks
(2019)Panoramic virtual reality video (PVRV) is becoming increasingly popular since it offers a true immersive experience. However, the ultra-high resolution of PVRV requires significant bandwidth and ultra-low latency for PVRV ... -
