This paper presents the delay results of wideband wireless channel measurements conducted in urban environment for base station to vehicle at 3.35 GHz and 5.4 GHz, respectively. Channel impulse responses are collected in both line-of-sight (LOS) and non-line-of-sight (NLOS) propagation. Based on the measurement data, power delay profiles are extracted. Delay statistical characteristics like mean excess...
A constantly increasing number of resource demanding applications from various scientific sectors are finding their way towards adopting Grid technologies in order to take advantage of their computational power. The aim of this paper is to demonstrate how tasks of large-scale distributed simulation can be scheduled based on GA in a Grid environment by taking into account load of computing nodes, network...
Parity redundancy is widely employed in RAID-structured storage systems to protect against disk failures. However, the small-write problem has been a persistent root cause of the performance bottleneck of such parity-based RAID systems, due to the additional parity update overhead upon each write operation. In this paper, we propose a novel RAID architecture, TRIP, based on the conventional parity-based...
