Mobile ad hoc networks (MANETs) are characterized by a dynamic topology and generally deployed in a hostile environment with limited resources. As a result, the nodes are more vulnerable and are often subject to failures. Therefore, the design of an efficient failure detector in MANETs is a very challenging issue as the detection is proved to be unreliable. Such an achievement amounts to balance between...
In this paper, we deal with failure detection in distributed systems under mobile environment constraints. For this effect, we propose a new protocol, called AFDAN (Accurate Fault Detection Protocol for Ad hoc Network), that is in charge of monitoring the distributed application against any node failure. The simulation results of our protocol show good performances in terms of accuracy and message...
Cloud infrastructures are prone to various anomalies due to their ever-growing complexity and dynamics. Monitoring behavior of dynamic resource management systems is necessary to guarantee cloud reliability. In this paper, we present AMAD, a system designed for detecting an abusive use of dynamic virtual machine migration, in the case of the abusive virtual machine migration attack. This attack is...
