Outsourcing data to the cloud becomes a trend for the users to reduce database management and maintenance cost. However, storing data on the cloud brings many security problems. Data privacy and query authentication are two critical issues to be resolved. Specially, they are important to aggregate queries of cloud data. The data owner must keep the sensitive data hidden and only the aggregate result...
The fault-tolerance control in scale-free wireless sensor networks against cascading failure is analysed in this paper. Based on the node load redistribution and constant capacity of the scale-free wireless sensor networks, a new load distribution model is proposed under a single random node failure. By the probability generating function method, the relationships between the load and the largest...
Wireless sensor networks have been studied extensively for their broad range of applications, especially in an environment with no infrastructure. And the nodes failures, link errors, and malicious node attacks are likely to occur quite frequently in wireless sensor networks. It affects the stability and reliability of data transmission. In this paper, we present a security fault-tolerant routing...
