Large-scale distributed systems deployed as Cloud datacenters are capable of provisioning service to consumers with diverse business requirements. Providers face pressure to provision uninterrupted reliable services while reducing operational costs due to significant software and hardware failures. A widely adopted means to achieve such a goal is using redundant system components to implement user-transparent...
Dependability is a critical concern in provisioning services in Cloud Computing environments. This is true when considering reliability, an attribute of dependability that is a critical and challenging problem in a Cloud context [2]. Fault-tolerance is one means to attain reliability, and is typically implemented by using some form of diversity. Federated Cloud, which is an emerging Cloud paradigm...
Cloud computing has emerged as popular paradigm that enables the establishment of large scale, flexible computing infrastructures that can offer significant cost savings for both businesses and consumers by allowing compute resources to be scaled dynamically to deal with current or anticipated usage [1]. This concept has been further strengthened with the emergence of federated computing Clouds that...
Over the last few years, the deployment of wireless sensor networks (WSNs) has been fostered in diverse applications. WSN has great potential for a variety of domains ranging from scientific experiments to commercial applications. Due to the deployment of WSNs in dynamic and unpredictable environments, these applications must have potential to cope with variety of faults. This paper proposes an energy-aware...
Dense collection of tiny Sensor Nodes (SNs), equipped with a variety of sensors are able to sense events, compute and communicate the estimations to the end user, form a distributed Wireless Sensor Network (WSN). The advances in WSNs have made it plausible to appraise critical aspects of object tracking WSNs that are continuous monitoring of object track and fault tolerance. This paper presents probabilistic...
