This paper proposes a distributed communication model-learning architecture for detecting anomalies in multiservice shared machine-to-machine (M2M) area networks. Since M2M devices are often located at remote areas, anomaly detection is essential for M2M services to promptly react to undesirable events (e.g. a device breaks or is stolen, misused, or spoofed). To autonomously set the threshold for...
In order to provide connectivity for various M2M devices in an easy and cost-effective manner, we propose the concept of "multi-service shared M2M area networks," which enables multiple M2M service providers to commonly use shared M2M gateways. The characteristics of M2M communications are analyzed in this paper based on various M2M use cases, and the technical challenges of shared M2M area...
The signaling traffic in mobile networks has been increasing rapidly due to the emergence of various types of devices such as smartphones and machine-to-machine (M2M) devices. This signaling traffic heavily burdens network controllers and could trigger network failures. Therefore, the need of a scalable device management method for reducing signaling traffic volume is increasing and the standardization...
We propose a novel communication system for evacuees of shelters, termed "Shelter Communication System (SCS)". SCS is composed of a computer (termed Shelter Server) connected to the Internet and a set of personal computers (termed shelter PCs), one in each shelter, connected to Shelter Server through a temporal link and the Internet. SCS provides a message communication service between shelters...
