Abstract:
With the development of Internet of Thing, the demand for clock synchronization in IoT application is
continues increasing. However, due to the heterogeneous devices and interfaces in IoT access system, most of the
traditional methods for clock synchronization are not applicable. In this paper, we present novel clock synchro-
nization architecture for IoT access system in the practical application scenario. By adopting the RTC, GPS,
NTP/SNTP and PTP technologies, the architecture can be implemented with dierent strategy to meet the
dierent needs of clock synchronization precision. A typical vehicle monitoring system based on the proposed
architecture for real-time video monitoring and environmental information acquisition has been designed and
implemented. The experimental results indicate the system can synchronize the clock with high precision and
reliability.

Abstract:
Football, also called soccer, is one of the most popular sports in the world, if one considers the number
of fans as well as the number of players. However, footballers face serious injuries during the match and even
during training. Concussion, hypoglycemia, swallowing the tongue and shortness of breath are examples of
the health problems footballers face, and in extreme cases, may lead to death. In addition, many sport clubs
and sport academies spend millions of dollars contracting new professional footballers or even developing new
professional footballers. The Internet of Things (IoT) is a new paradigm that combines various technologies to
enhance our lives. Today’s technology can protect footballers by diagnosing any health problems, which may
occur during the match or training session, which, if detected early, may prevent any adverse eects on their
long-term health. This paper proposes an IoT-based architecture for the sport of football, called IoT Football.
Our proposal aims to embed sensing devices (e.g. sensors and RFID), telecommunication technologies (e.g.
ZigBee) and cloud computing in the sport of football in order monitor the health of footballers and reduce
the occurrence of adverse health conditions. The aim is to integrate the IoT environment, in particular the IoT
application, into the field of sport in the form of a new application.
8. Design of the mass multimedia files storage architecture based on Hadoop.

Abstract:
With the development of social network and video sites, the amount of images and videos being uploaded
to the internet is rapidly increasing, and it is more and more dicult to storage and process the mass network
images and videos. How to storage, manage and classify mass network images and videos eectively, and
provide an excellent experience for users has been an urgent problem. Hadoop distributed file system (HDFS)
becomes a representative cloud storage platform, benefiting from its reliable, scalable and low-cost storage
capability. However, HDFS is not designed for storing mass small files. This paper presents a Hadoop-based
mass multimedia files storage architecture. The core idea of this architecture is that merge the small images
and video files to a Bundle, and provide a unified interface to handle mass images and videos. It’s a good
solution to the problem of small files. The experimental results show that the approach can achieve a better
performance.
