The occurrence of congestion has an extremely deleterious impact on the performance of Wireless Sensor Networks (WSNs). This article presents a novel protocol, named COALA (COngestion ALleviation and Avoidance), which aims to act both proactively, in …
As security is a growing concern for modern information systems, Security Requirements Engineering has been developed as a very active area of research. A large body of work deals with elicitation, modelling, analysis, and reasoning about security …
Internet of Things (IoT) can be seen as the main driver towards an era of ubiquitous computing. Taking into account the scale of IoT, the number of security issues that emerge are unprecedented, therefore the need for proposing new methodologies for …
In this paper, a software tool for security analysis of IoT systems is presented. The tool, named ASTo (Apparatus Software Tool) enables the visualization of IoT systems using a domain-specific modeling language. The modeling language provides …
This paper proposes a conceptual model to support decision makers during security analysis of Internet of Things (IoT) systems. The world is entering an era of ubiquitous computing with IoT being the main driver. Taking into account the scale of IoT, …
Near Field Communication (NFC) has enabled mobile phones to emulate contactless smart cards. Similar to contactless smart cards, they are also susceptible to relay attacks. To counter these, a number of methods have been proposed that rely primarily …
It is well acknowledged that one of the key enabling factors for the realization of future 5G networks will be the small cell (SC) technology. Furthermore, recent advances in the fields of network functions virtualization (NFV) and software-defined …
Device-to-Device (D2D) communication is expected to be a key feature supported by 5G networks, especially due to the proliferation of Mobile Edge Computing (MEC), which has a prominent role in reducing network stress by shifting computational tasks …
The volume of banking transaction has increased considerably in the recent years with advancement in financial transactions payment methods. Consequently, the number of fraud cases has also increased, causing billion of dollar losses each year …
Research on next-generation 5G wireless networks is currently attracting a lot of attention in both academia and industry. While 5G development and standardization activities are still at their early stage, it is widely acknowledged that 5G systems …
