An intelligent agent-based routing structure for mobile sinks in WSNs
TLDR
IAR, an Intelligent Agent-based Routing protocol that provides efficient data delivery to mobile sink is proposed and the proposed algorithm reduces signal overhead and improve degraded route called triangular routing problem. Expand
Multi-dimensional channel management scheme to avoid beacon collision in LR-WPAN
TLDR
The simulation results demonstrate that the proposed scheme can minimize the possibility of beacon collisions by efficiently managing the multiple available channels in a hybrid manner combining proactive and reactive methods while the dissipated power consumption of PAN coordinator that uses MDS is more than that of PC that use IEEE 802.15.4.

TLDR
This paper proposes a novel, fast, and accurate water leakage detection system with an adaptive design that fuses a one-dimensional convolutional neural network and a support vector machine and proposes a graph-based localization algorithm to determine the leakage location. Expand
A design and implementation of wireless sensor gateway for efficient querying and managing through World Wide Web
TLDR
This paper presents the architecture of the sensor gateway for Web-based management and its implementation details, and assumes that wireless sensor networks have 3-level regional hierarchy, but the gateway is flexible enough to cooperate with other type sensor networks. Expand
A TDoA-based localization using precise time-synchronization
TLDR
The accuracy of the proposed and improved time-synchronization and measurement of error of TDoA-based location detection technology is evaluated, and, thus, T doA- based location measurement error is greatly improved with the proposed method for time- Synchronization error reduction. Expand
Performance Improvement by Packet Buffering in Mobile IP Based Networks
TLDR
