Secure routing is considered as one of a key challenge in mesh networks because of its dynamic and broadcasting nature. The broadcasting nature of mesh environment invites number of security vulnerabilities to come and affect the network metrics drastically. Further, any node/link failure of a...

Scientific workflows are very complex, large-scale applications and require more computational power for data transmission and execution. In this article, the authors address the problem of scheduling scientific workflow on a number of virtual machines (VM) with the objective of reducing the...

With mission critical web applications and resources being hosted on cloud environments, and cloud services growing fast, the need for having greater level of service assurance regarding fault tolerance for availability and reliability has increased. The high priority now is ensuring a fault...

This article describes how data replication plays an important role in distributed systems. It primarily focuses on the redundancy of data at two or more nodes, to achieve both fault tolerance and improved performance. Therefore, many researchers have proposed various data replication algorithms...

This article describes how fault tolerance is an essential issue for many WSN (Wireless Sensor Network) applications such as wildlife monitoring, battlefield surveillance and health monitoring. It represents a great challenge for researchers regarding to the characteristics of sensor nodes which...

Load management of resources during high load demand managed by load management mechanism. An efficacious resource management algorithm effectively manages the load imbalance. Virtual Machine (VM) migration policy can maximize the throughput of the Cloud. Overloaded User Base (UB) high resource...

Nowadays, computing calculations are becoming more and more demanding due to the huge pool of resources available. This demand must be satisfied in terms of computational efficiency and resilience, which is compromised in distributed and heterogeneous platforms. Not only this, data obtained are...

We describe the design and implementation of a complete flight-software operating system (OS) for a high-performance CubeSat carrying a third-party payload. This CubeSat's mission is to carry out research experiments on this payload while in low earth orbit. These experiments may be specified...

In the current era, Internet is the fastest growing technology. It is a global network of distributed systems that interconnects with each other to share various resources and computation. The complexity of the distributed systems is rapidly increasing, which leads to an increased susceptibility...

One of the main challenges in cloud computing is to build a healthy and efficient storage for securely managing and preserving data. This means a cloud service provider needs to make sure that its clients' outsourced data are stored securely and, data queries and retrievals are executed...
