Mobile devices have received much research interest in recent years. Mobility raises new issues such as more dynamic context, limited computing resources, and frequent…

Blind source separation of acoustic signals in realistic environments based on ICA in the time‐frequency domain

Shuxue Ding, Andrzej Cichocki, Jie Huang, Daming Wei

We present an approach for blind separation of acoustic sources produced from multiple speakers mixed in realistic room environments. We first transform recorded signals into the…

Peering by exploiting peer heterogeneity

Hung‐Chang Hsiao, Chung‐Ta King, Shih‐Yen Gao

Resource discovery in peer‐to‐peer (P2P) systems have been extensively studied. Unfortunately, most of the systems studied are not designed to take advantage of the heterogeneity…

Xuhui Li, Zhiyong Peng, Jiannong Cao

Mobile agent, as a new mobile computing technology, has been applied to various parallel and distributed computing problem solutions. Several mobile agent systems have been built…

Impact of topology on Bluetooth Scatternet

Leping Huang, Hongyuan Chen, T.V.L.N. Sivakumar, Tsuyoshi Kashima, Kaoru Sezaki

To utilize Bluetooth as a layer 2 multi‐hop subnet for global IP network, there are two missing protocols in current Bluetooth stack: network formation and routing. In this paper…

Mechanically supporting case analysis for verification of distributed systems

Takahiro Seino, Kazuhiro Ogato, Kokichi Futatsugi

The OTS/CafeOBJ method can be used to formally model, specify and verify distributed systems such as security protocols and railroad systems. A distributed system is modeled as an…
