Network virtualization has been regarded as a core attribute of Future Internet. To improve the quality of virtual network, it is important to diagnose the faulty components quickly and accurately. Recently more and more researches focus on end-user fault diagnosis, which can fit incomplete knowledge and dynamic challenges. In this paper, we present a fault diagnosis system called DiaEO in virtual...
Due to single reference information priority, poor network topology adaptability, low positioning accuracy and high computational complexity, the multi-hop localization approaches for wireless sensor networks have many limitations in application. In view of this, a novel grid-scan-based multi-hop localization algorithm (GSML) is proposed. We construct a more realistic weighted constrained model for...
In recent years, there has been an increasing interest in sensor networks, in which sensor nodes such as temperature or humidity sensors communicate with each other for environmental monitoring and so on. In sensor networks, it is important to reduce the energy consumption, since sensor nodes have limits in battery. Most researches achieve this by reducing sensor amount of transmitted data. However,...
