Summary form only given. The complete presentation was not made available for publication as part of the conference proceedings. In this half day tutorial, we present an overview of the JESD204 interface protocol, key performance metrics and challenges in an embedded silicon implementation. We discuss system budgeting of the jitter components in the physical channel and present tradeoffs to meet the...
This paper relates to the problem statement of distribution of heterogeneous information and communication system capacity among multiple service flows. We consider the case study of multi-commodity flow problem in terms of utility functions maximization. This approach differs from previously known by separating the optimization problem into layers based on Bellman's Principle of Optimality. It simplifies...
Device-to-device transmission technology can help base stations achieve high transmission rates and meet high-capacity requirements. It is also a key technology for future markets. Additionally, the coexistence of licensed and unlicensed bands will be relevant to the landscape of the emerging 5th-generation cellular systems. However, there is a shortage of research on efficient transmission during...
IEEE 802.11ac standard aims at providing gigabit throughput with users. One of the main features of IEEE 802.11ac standard is the support of wider bandwidths (20/40/80/160 MHz) than those of previous IEEE 802.11n standard (20/40 MHz) on 5 GHz band. Through wider bandwidths, which consists of the primary channel and secondary channels, enormous amount of throughput enhancement can be achieved. The...
Multipath transport can simultaneously utilize many interfaces of a terminal to maximize the transfer throughput. However, when sharing the same bottleneck link with single-path flows, the multipath flows will occupy more network bandwidth and it will lead to the unfairness of resource allocation. In this paper, we propose a Congestion Control method with Fairness (CCMF) for multipath transport. CCMF...
Memory interference is a critical impediment to system performance in MPSoCs. To address this problem, we first propose a Locality-Aware Bank Partitioning (LABP), which partitions memory banks according to applications' memory access behavior. The key idea is to separate memory intensive applications with high row-buffer locality from the other applications. Moreover, we integrate LABP with a bandwidth...
Multi-granularity memory system provides multiple access granularities for the applications with various spatial localities. In the multi-granularity access pattern, the one-size-bandwidth NoC design cannot utilize the bandwidth efficiently. We propose a novel NoC design, called BoDNoC, which can merge multiple narrow subnets to provide various bandwidths for access data. The new design also adopts...
Satellites give exceptional points of interest, for example, remote scope with fast sending, separation lack of care, transmission capacity on interest, safety to physical debacles, and offering broadband connections. TCP has been produced for wired systems that have a lower delay and a low piece mistake rate. It is the most usually utilized transport layer convention as a part of the Internet and...
The mobile devices are becoming the important part in our day to day life. These are now one of the basic needs of our daily life. These devices are used to share the data of interest with one another. Data may be in the form of picture or video clip , news etc. But sometimes , data cannot reach to the user who is interested ,because of delaying of messages. Sometimes nodes do not want to loose their...
Cluster computing in ad hoc network draws special attention from the research community due to its inherent support for group communication in varied application domains like emergency and rescue operations, etc. Context sensitive aware cluster computing yields maximum benefits and advantages than the traditional computing. The Cluster Head (CH) and the Cluster Members (CM) effectively coordinate...
Unlimited voice services no longer command premium pricing, but are viewed as “table stakes” in a broader service offering that must now include multimedia (voice, data, video) communications with a mobility component. As a result of this shift, many service providers are trying to adopt, Long Term Evolution (LTE) network strategy to deliver this multimedia experience to their subscribers [1]. Today,...
There has been rapid growth in the area of wireless communication by Wireless Mesh Networks (WMNs) where routing metric is the key metric to find the optimized route in WMNs. For obtaining optimal performance, integrating multiple performance metrics into a routing protocol is effective, as single metric will not be able to satisfy the thorough requirement of WMNs. This paper has proposed a new routing...
3GPP has been working in establishing a new network infrastructure based on unlicensed spectrum known as LTE Secondary Cell (SCell) in a carrier aggregation scenario in which LTE user terminals would still be anchored to an LTE Primary Cell (PCell) over licensed spectrum. On this scenario, best-effort content would be delivered on the unlicensed band SCell, while QoS traffic and control signaling...
The performance of wireless mesh networks (WMNs) deployed for Internet access in rural settings is affected by several factors. Typically, deployments in African domains use cheap and computationally constrained devices with challenges such as power fluctuations, gateway congestion, VSAT communications asymmetry and low bandwidth, which affects throughput under dynamic scenarios. Caching methods can...
Radio access technology (RAT) selection has recently received much attention from the research community due to the increasing deployment of heterogeneous wireless networks. Most prior works mainly focus on proposing an efficient algorithm that yields good performances, and evaluate their solutions on a certain network model, particularly in cases when every user can connect to all the available base...
This paper proposes a methodology to reduce Packet Error Rate (PER) of a Very High Throughput (VHT) physical layer frame in a WiFi Direct (WD) 802.11ac Wireless Local Area Network (WLAN) by examining the loss of individual fields. To this end, a 2x2 Multiple Input Multiple Output - Orthogonal Frequency Division Multiplexing (MIMO-OFDM) transceiver is implemented under a TGn multipath fading channel...
The research and education network is the crucial driving infrastructure that fosters advances in networking. Because of best efforts nature of the Internet, services offered to researches sometimes cannot meet high throughput requirements. The network path is also swamped with network and security devices which create bottlenecks. Many efforts have been proposed to ease this problem, for example,...
The efficient allocation of multi-interface multi-channel Wireless Mesh Network channel resources is a hot topic recently. Effective channel management mechanisms need to be designed to ensure the full and efficient use of channel resources. In this paper, combined with the channel load that network buyers perceived, the channel reassignment problem of multi-interface multi-channel Wireless Mesh Network...
SATA is the de-facto standard computer interface that connects a host, typically a computing device, to a persistent storage device, such as a hard drive or solid-state drive. In order for FPGA-based designs to be able to leverage the variety of persistent storage devices, a SATA core is needed. Over time, the SATA standard has been revised to provide greater bandwidth, with SATA III being the newest...
In today's super system scenario the computation effectiveness is obtained from multiple processors which are connected to themselves and to their memory modules through multistage interconnection networks (MIN) So performability of these multistage interconnection networks (MIN) Plays vital role in effective and efficient processing of these super systems. In this paper performance of these MIN namely...
