In a SoC environment, asynchronous design techniques offer solutions for problems of synchronous design techniques. Asynchronous FIFOs have the advantages of easier interconnection methods and higher throughput than synchronous ones. Low latency and high throughput are two imp ortant standards in asynchronous FIFOs. We present low latency asynchronous FIFO in the paper, which optimizes GasP[6]. Pre-layout of HSPICE simulations of a 8-stage FIFO on 1-bit datapath using Anam's 0.25$\mu\textrm{m}$ technology indicates 17% lower latency than GasP.

Change in lantency of otoacoustic emission(OAE) may indicate clinically and diagnostically important change in the status of the nervous system. A low signal-to-noise ratio of OAE signal makes it difficult to estimate small, transient, time-varing changes in latency. we present an adaptive algorithm that estimates small latency change value even when OAE signal amplitudes are time-varing.

During the summer of 2010, the first low-latency search for gravitational waves from compact binary coalescences was performed using the LIGO and Virgo instruments. The aim was to provide triggers for follow-up by electromagnetic telescopes. In this presentation we will describe the low-latency pipeline used to produce these triggers, including the time-delay-based procedure used to localize them on the sky.

An automatized latency calculation method of evoked otoacoustic emission is proposed. Averaged e-OAE signal is measured from normal adult and it is processed by IBM-AT computer for latency calculation. After partition of stimulated and emitted signal on the time axis by converted linear prediction coding spectrum, latency is calculated by cross correlation method. The output is also compared with those of conventional autocorrelation and pure cross correlation methods. The result show that proposed method has better performance than those of conventional ones.

One of the remarkable problems in PIM-DM (Protocol Independent Multicast - Dense Mode) is the join latency time, increasing for specific periods. The reason of this problem is proved to the confusion of flooding prune message and leave prune message. We propose a new solution to this problem, reducing the average join latency by 37.4%, and prove the proposed solution by network simulation.

In wireless access networks, it is extremely important to provide high quality of real time and interactive services, including voice and video traffic. Furthermore, low latency communication is shifting toward new paradigm which enhances user's high quality of experience, meeting the requirements for specific applications such as tactile internet, remote-control robot and machines, and mission critical application. In this paper, we introduce the approaches to achieve the extremely low latency service. The approaches include the core requirements and the key technologies providing low latency communication maintaining high reliability in wireless access networks.

In this paper, an adaptive MAC protocol (variable load adaptive (VLA)-MAC) is proposed for wireless sensor networks. This protocol can achieve high energy efficiency and provide low latency under variable-traffic-load conditions. In the case of VLA-MAC, traffic load is measured online and used for adaptive adjustment. Sensor nodes transmit packets in bursts under high load conditions to alleviate packet accumulation and reduce latency. This also removes unnecessary listen action and decreases energy consumption in low load conditions. Simulation results show that the energy efficiency, latency, and throughput achieved by VLA-MAC are higher than those achieved by some traditional approaches.

그리드 컴퓨팅은 우주과학, 수학적인 큰 문제들을 해결하기 위해 네트워크 상에 분산된 수많은 컴퓨터들의 컴퓨팅 파워와 대용량 저장장치를 공유하여 문제들을 해결할 수 있는 기술이다. 그리드 컴퓨팅의 환경은 WAN으로 구성된 각기 다른 성능과 이질적인 네트워크 상태들로 구성된다. 이런 이질적인 성능요소들을 고려하여 계산 작업에 반영시키는 것이 무엇보다 중요하다. 본 논문에서는 WAN 환경의 네트워크 상태 정보 중 latency, bandwidth, latency-bandwidth 혼합정보들을 고려하여, 노드별로 작업 프로세스 수를 결정하는 방법을 제안한다. 본 논문에서의 네트워크 성능정보 수집은 NWS(Network Weather Service)를 통해 이뤄지며, 평가결과 네트워크 성능정보를 고려하지 않은 균등방식에 비해서 latency, latency-bandwidth 고려한 방법의 결과가 9%, 31% 성능이 향상되었다.

Cross correlation method was newly applied for the calculation of latency of evoked otoacoustic emission. The latency was calculated from the main peak of cross correlation function, which is one of possible definition of latency. The output was also compared with those of conventional autocorrelation method. The results show that cross correlation method has better performance than that of conventional method.

Mobile IP Low Latency Handoffs［1］는 Mobile IP 등록 요청 절차를 처리하는데 있어서 단말의 지연 때문에 생기는 블록킹 시간을 최소화 시켜 실시간 서비스를 가능하게 해 준다. 그러나 인증, 권한 검증, 과금을 지원하는 AAA 기반의 Mobile IP 망에서는 매 지역 등록이 일어날 때마다 새로운 세션 및 세션 키가 필요하며, 이를 위해 홈 망까지 등록 절차가 수행되어야 한다. 이로 인해, 이동 노드 재인증 절차와 방문 망에서 홈 망까지의 트랜잭션으로 인한 통신 지연이 발생한다. 이러한 지연을 줄이기 위해서 본 논문에서는 홈 망의 AAA 서버가 관여되지 않고, 이전에 할당된 세션 키를 재 사용하여 Low Latency Handoffs를 수행하는 기법을 제안한다. 이 기법에서는 이전 방문 에이전트와 새로운 방문 에이전트간 세션 키를 교환하는 단계에서 발생하는 보안 취약성을 해결할 수가 있으며 홈 망까지 트랜잭션이 필요 없고, 세션 키의 기밀성이 제공되므로 이동 노드가 빠르고 안전하게 핸드오프를 수행할 수 있다.
