Linux servers with heterogeneous architectures present a new challenge for fault management. With the significant increase in the numbers and types of hardware components, separate fault management becomes more complex and inefficient. It is clear that centralized management, automatic recovering and scalable design must be incorporated in the modern fault management system. Based on the ccNUMA architecture,...
Consider a system composed of mobile robots that move on the plane, each of which independently executing its own instance of an algorithm. Given a desired geometric pattern, the flocking problem consists in ensuring that the robots form this pattern and maintain it while moving together on the plane. In this paper, we explore flocking in the presence of faulty robots, where the desired pattern is...
Robotics has been paid a lot attentions because of its wide applications, like explore unknown planet or rescue people after earthquake or fire. In a group of mobile robots, robots are usually weak and are easy to get crash, especially working in dangerous or harsh environment. Unfortunately, to the best of our knowledge, only a few studies address on robot failure, especially transient failure. Therefore,...
In this paper, we give a survey on fault tolerant issue in distributed systems. More specially speaking, we talk about one important and basic component called failure detection, which is to detect the failure of the process quickly and accurately. Thus, a good failure detection method will avoid the further system lost due to process crash. This survey provides the related research results and also...
Consider a system composed of mobile robots (mobile sensors) that move on the plane, each of which independently executing its own instance of an algorithm. Given a desired geometric pattern, the flocking problem consists in ensuring that the robots form this pattern and maintain it while moving together on the plane. In this paper, we look at the flocking problem in the presence of faulty robots,...
To solve the non-transitive connectivity (NTC) problem which existing widely in networks, this paper proposes a method to solve the NTC problem in overlay network by using uncertainty DHT to establish structured network. Through relieving the relationship between node ID of bottom layer and position of logical space, it will avoid the effect of NTC node to network structure, at the same time using...
