In this paper we present an online algorithm that attacks the problem of placing relay nodes in regions where high localized congestion is detected. Congestion refers to the netwo...
In this paper an overview of novel scavenging approaches for almost autonomous ICT applications will be discussed and evaluated in terms of efficiency, integrability, cost and app...
The sensor networks had been used for various application areas and showed effectiveness under the prior application planning and right circumstances that includes cost, data hand...
We present a Variable Neighborhood Search approach for a network design problem occurring in real world when the bandwidth of an existing network shall be enhanced. Using two diff...
This paper presents initial experiment results toward realizing a multi-core CPU for wireless sensor nodes. The multi-core CPU reduces power consumption with enabling users to eas...
We describe our development work of tools for data collection and data management for wearable and ubiquitous computing. By embedding different kinds of sensory devices on the us...
In this paper, we present the first heuristic for fully distributed bootstrapping of peer-to-peer networks. Our heuristic generates a stream of promising IP addresses to be probe...
In the ubiquitous computing environment, we believe that P2P-based context-aware application utilizing sensing data is important. However, since sensors are not placed under the c...
