Information on contacts between individuals within a population is crucial to inform disease control strategies, via parameterisation of disease spread models. In this study we investigated the use of dog-borne video cameras-in conjunction with global positioning systems (GPS) loggers-to both characterise dog-to-dog contacts and to estimate contact rates. We customized miniaturised video camera...

Campus wireless LANs (WLANs) are complex systems with hundreds of access points (APs) and thousands of users. To analyze the performance of wireless networking protocols, researchers need to construct simulations and testbed experiments that reproduce the characteristics of these networks. However, the generation of realistic models and benchmarks is challenging and there is only a limited set ...

A secure roaming protocol for mobile networks is proposed. Roaming has been analysed in some schemes from the security point of view; however, there are vulnerabilities in most of them and so the claimed security level is not achieved. The scheme offered by Wan et al. recently is based on hierarchical identity-based encryption, in which the roaming user and the foreign network mutually authenti...

Key Establishment for Wireless Roaming (KE-WR) is expected to ensure a mobile user to establish a fresh session key with a foreign WSP and also roam from one foreign network domain to another while enjoying the roaming services. However, so far there is no ID-based KE-WR protocol proposed in the literatures with a formal security proof in an appropriate model. The main work of this article addr...

We present a generic business model for (WLAN) hotspots that comprises a role, resource and revenue model of a value network. We focus on the role model and the roaming model, as they are the essential to a wireless hotspot enterprise. In addition, we describe an instantiation of these models to arrive at a viable roaming business case for stakeholders in a hotspot enterprise in the Netherlands...

The paper proposes a scheme, referred to as proactive server roaming, to mitigate the effects of denial of service (DoS) attacks. The scheme is based on the concept of ‘‘replicated elusive service’’, which through server roaming, causes the service to physically migrate from one physical location to another. Furthermore, the proactiveness of the scheme makes it difficult for attackers to guess ...

Control measures for canine rabies include vaccination and reducing population density through culling or sterilization. Despite the evidence that culling fails to control canine rabies, efforts to reduce canine population density continue in many parts of the world. The rationale for reducing population density is that rabies transmission is density-dependent, with disease incidence increasing...
