Nowadays, the Internet of Things is able to provide more advanced services to people, which connects a variety of devices, systems and applications. However, it covers a variety of devices, protocols and applications, which makes it much more complex. In the main application areas, wireless sensor networks with a frequent but short communication character, it requires an efficient and flexible protocol...
This paper proposes PriorityMAC, a priority-enhanced medium access control protocol, designed for critical traffic in industrial wireless sensor and actuator networks (IWSAN). A notable trend in industrial automation in recent years has been the replacement of wired communication by IWSANs. Exceeding the required delay bound for unpredictable and emergency traffic could lead to system instability,...
In the following years, the desktop-based applications will be changed to cloud computing gradually. Since all users' profile and context data will be stored on the service supplier side based on their ID. ID is becoming a security bottleneck: attackers can trace all other information via user ID. Increasingly, a simple service may be involved in a chain of service clouds; each cloud is able to access...
Due to the rapid growth of wireless communication, it is now believed that wireless devices with multiple interface support will highly increase in the near future. In the research community of Network Simulator, there has recently been quite a large interest in extending the current wireless node implementation so as to be able to include more than one radio interface to work simultaneously. We focus...
