As a distributed system, Hadoop heavily relies on the network to complete data processing jobs. While Hadoop traffic is perceived to be critical for job execution performance, the actual behaviour of Hadoop network traffic is still poorly understood. This lack of understanding greatly complicates research relying on Hadoop workloads. In this paper, we explore Hadoop traffic through experimentation...
Among the diesel traction railway tunnels on Lhasa-Rikaze line of China, some of two tunnels are adjacent. When a train gets across a given tunnel, air pollutants extruded from the exit of the tunnel may diffuse towards the entrance of its neighboring tunnel and thus it results in thereof air pollution. The so-called cross pollution can affect the established ventilation scheme of excluding pollutants...
For underwater acoustic networks, the selection of MAC (medium access control) protocols will greatly affect the performance of the system. such as throughput and end-to-end delay. The ALOHA scheme takes advantage of simplicity, but the throughput is greatly decreased in the condition of high traffic and unstable channel. In this paper, we propose an alternative random access FH-CDMA underwater acoustic...
