Fault detection in modern networks is done with a set of specially instrumented nodes which send probes to find faults. These probes generate additional traffic in network and compete with other regular traffic for bandwidth. In this paper we consider the problem of dynamically adapting the probes based on traffic dynamics experienced by nodes. We ...

The evolution of software defined networking (SDN) has played a significant role in the development of next-generation networks (NGN). SDN as a programmable network having “service provisioning on the fly” has induced a keen interest both in academic world and industry. In this article, a comprehensive survey is presented on SDN advancement over co...

With the development of the Internet, the Internet applications represented by Peer-to-Peer (P2P) streaming systems bring more and more communication overhead. In order to alleviate communication pressure of the Internet, and improve the user’s access experience, we aim at taking full advantage of peer upload bandwidth contributions with a cache on...

Continuous monitoring of network resources enables to make more-informed resource allocation decisions but incurs overheads. We investigate the trade-off between monitoring costs and benefits of accurate state information for a routing problem. In our approach link delays are modeled by Markov chains or hidden Markov models. The current delay infor...

Network slicing is one of the key enabling technologies for 5G networks. It allows infrastructure owners to assign resources to service providers (tenants), which will afterwards use them to satisfy their end-user demands. This paradigm, which changes the way networks have been traditionally managed, was initially proposed in the wired realm (core ...

Frost is an agro-meteorological event which causes both damage in crops and important economic losses, therefore frost prediction applications (FPA) are very important to help farmers to mitigate possible damages. FPA involves the execution of many CPU-intensive jobs. This work focuses on efficiently running FPAs in paid federated Clouds, where cus...

Wireless ad hoc and sensor networks play an important role in providing flexible deployment and mobile connectivity for next generation network. Since there is no fixed physical backbone infrastructure, some of the nodes are selected to form a virtual backbone. Efficient algorithms for identifying the Minimum Connected Dominating Set (MCDS) have ma...

When surrounded by the heterogeneous networks environment, mobile terminals are often expected to select an optimal network quickly from the detected alternatives to ensure the required or better quality of service. How to reduce the probability of ping-pong effect of the process as much as possible is one of the most prominent challenges. From the...

In Multimedia Sensor Networks (WMSNs) the devices are interconnected in the wireless manner that is able to ubiquitously retrieve multimedia content such as video and audio streams, still images, and scalar sensor data from environments. Many research works have been undertaken to enhance the quality of multimedia contents and energy consumption, b...
