The paper explains and discusses an innovative agricultural appliance, based on vertical farming and hydroponics. The innovative and smart model was launched by a brilliant woman, winner of several awards. Applying her engineering skills, the female ...

The data-intensive applications employ complex workflow graph models in dynamic networks having heterogeneity and mobility of nodes, which result in enhanced end-to-end delay in executions. The current workflow models lack structural stability for ...

A Mobile Ad hoc Network (MANET) can work well only when the mobile nodes behave cooperatively in packet routing. To reduce the hazards from malicious nodes and enhance the security of the network, this paper extends an Ad hoc On-Demand Multipath Distance ...

Streams of data are produced today at an unprecedented scale. Efficient and stable processing of these streams requires a careful interplay between the parameters of the streaming application and of the underlying stream processing framework. Today, ...

The Data Centre concept has evolved, mainly due to the need to reduce expenses with the required physical space to store, provide and maintain large computational infrastructures. The Software-Defined Data Centre (SDDC) is a result of this evolution. ...

The dependability and security properties of a system could be impaired by a failure or by an opponent that exploits its vulnerabilities. State Machine Replication (SMR) is a technique widely used to implement fault-tolerant systems, mitigating these ...

Lévy walk has attracted attention for its search efficiency. Homesick Lévy walk is a family of random walks whose encounter probability of one another is similar to the one of human behaviour. However, its homing behaviour limits the search area of each ...

Network Functions Virtualisation (NFV) presents several advantages over traditional network architectures, such as flexibility, security, and reduced CAPEX/OPEX. In traditional middleboxes, network functions are usually executed on specialised hardware (...

Cloud computing has deeply affected the structure of modern ICT infrastructures. It represents an enabling technology for novel paradigms such as Network Function Virtualisation (NFV), which proposes the virtualisation of network functions to enhance the ...

In this paper, two strategies for handling continuous k-nearest neighbour queries for location-based services are proposed. CKNN1 and CKNN2 utilise a validity (i.e., safe) region approach for minimising the number of query requests that need to be send to ...

Security assessment is a very time- and money-consuming activity. It needs specialised security skills and, furthermore, it is not fully integrated into the software development life-cycle. One of the best solutions for the security testing of an ...

The proliferation of Electric Vehicles (EVs) is exponential. However, the power grid is not able to provide simultaneous charging of several EVs due to limited power production capabilities and old distribution infrastructure. Scheduled charging is one of ...
