Implementing a trusted, cost-efficient, automatic monetization solution of... View full abstract»

Software defined networking (SDN) and network function virtualisation (NFV) have become hot topics in recent years. On one hand, SDN decouples the control plane from the data plane allowing the rapid innovation and the introduction of new services in an easy way. On the other hand, currently proprietary appliances such as load balancers and firewalls are implemented in hardware, NFV aims to change... View full abstract»

Internet of Things (IoT) represent a network of resource-constrained sensor devices connected through the open Internet, susceptible to misuse by intruders. Traditional standalone intrusion detection systems (IDS) are tasked with monitoring device behaviours to identify malicious activities. These systems not only require extensive network and system resources but also cause delays in detecting a ... View full abstract»

Internet of Things (IoTs) era is expected to empower all aspects of Intelligent Transportation System (ITS) to improve transport safety and reduce road accidents. US Federal Communication Commission (FCC) officially allocated 75 MHz spectrum in the 5.9 GHz band to support vehicular communication. The authors studied the application of cognitive radio (CR) technology to IoVs to increase the spectra... View full abstract»

Device-to-device (D2D) communication is a promising technology for the next generation mobile communication networks (5G). Indeed, it is expected to allow high throughput, reduce communication delays and reduce energy consumption and traffic load. D2D technology will enhance the capacity and the performance of traditional cellular networks. Security issues must be considered in all types of commun... View full abstract»

Mobility management has always been a challenging and important issue for the next-generation all-IP mobile networks. Seamless mobility is one of the requirements to provide real-time services in such networks. Proxy Mobile IPv6 (PMIPv6) has been developed by the Internet Engineering Task Force (IETF) as a network-based mobility management protocol to support the mobility of IP devices. Although s...

In a typical healthcare monitoring system, the cloud is the preferred platform to aggregate, store and analyse data collected from Medical Internet of Things (or MIoT) devices. However, remote cloud servers and storage can be a source of substantial delay. To overcome such delays, an intermediate layer of fog or edge nodes is used for localised processing and storage of MIoT data. To this end, an ... View full abstract»

To satisfy the recent growth of mobile data usage, small cells are recommended to deploy into conventional cellular networks. However, the massive backhaul traffic is a troublesome problem for small cell networks, especial in wireless backhaul transmission links. In this study, backhaul traffic models are first presented considering the Gauss-Markov mobile models of mobile stations in small cell n... View full abstract»

This study deals with the impact of unlicensed Internet of Things (IoT) network coexistence in terms of packet collision. The classical packet collision studies based on the Poisson distributed process generally assume homogeneous networks with packets of equal lengths. The authors propose a new approach which can be applied to a more general context including heterogeneous networks and different ... View full abstract»

Address resolution protocol (ARP) cache poisoning is mostly used to perform man-in-the-middle (MITM) and denial of service (DoS) attacks for sniffing and network services disruption, respectively, in switch LAN networks. The former attack affects the privacy of a network user, whereas the latter attack causes huge damage to networks in terms of unavailability of services. There are many security s...

When wireless sensor network (WSN) is running, it needs data acquisition, fusion, and transmission, which makes the attacker distribute the malware code to the network to destroy the normal operation of the network. In this study, an improved two-dimensional (2D) cellular automata model and a multi-player evolutionary game model are proposed to describe the propagation process of malware propagati...

A new model for malicious file propagation and transmission in a computer network is formulated. This model introduced a cure rate ξ (E-cure rate) which is calculated after the regular running of anti-virus in the systems of the computer network. This will result in monitoring the anti-virus efficiency in fighting not only a local malicious file but also the global spreading of such a file.... View full abstract»
