Failures are normal rather than exceptional in the cloud computing environments. To improve system availability, replicating the popular data to multiple suitable locations is an advisable choice, as users can access the data from a nearby site. This is, however, not the case for replicas which must have a fixed number of copies on several locations. How to(More)
Coverage control is one of the key problems of research and application of wireless sensor networks. In this paper, the coverage control problem for hybrid wireless sensor network consisting of both static and mobile sensors is investigated. A dynamic repair mechanism based on the ant colony algorithm is proposed for coverage blind spots found in the(More)
