Virtual cloud network services let users have their own private networks in the public cloud. IPsec gateways are growing in importance accordingly as they provide VPN connections for customers to remotely access these private networks. Major cloud providers offer IPsec gateway functions to tenants using virtual machines (VMs) running a software IPsec gateway inside. However, dedicating individu...

The Internet access from mobile networks is gaining great interest from the research community. Mobile Ad-hoc Networks consist of mobile nodes without central administration, having no physical links and not follow particular routing topology due to frequent mobility of nodes. Various routing protocols or Gateway Discovery Approaches have been designed to discover proper internet gateway and to...

which administered grants to increase the knowledge base around drug-related deaths. 2 The National Treatment Agency for Substance Misuse (NTA) is a special health authority within the NHS, established by Government in 2001, to improve the availability, capacity and effectiveness of treatment for drug misuse in England. Treatment can reduce the harm caused by drug misuse to individuals' well-be...

Science gateways provide user interfaces and highlevel services to access and manage applications and data collections on distributed resources. They facilitate users to perform data analysis on distributed computing infrastructures (DCIs) without getting involved into the technical details. The e-BioInfra Gateway is a science gateway for biomedical data analysis on a national grid infrastructu...

We propose a WAP-based, Push-enabled mobile Internet application platform, called MAP, to provide extensive services for users in the mobile environment. The goal of this platform is to provide a flexible, scalable and rapid-service-creation environment for mobile Internet applications to operate in. MAP has four main components, which have been designed and implemented: (1) a WAP micro-browser...

In this paper, we propose a load balancing strategy that has the following features: (1) estimating the potential load of real gateways with low computation and no communication overhead, (2) asynchronous alarm sent when the utilization of a real gateway exceeds a critical threshold, and (3) WAP-awareness. We also propose a scalable WAP gateway (SWG) that consists of a WAP dispatcher and a clus...

WAP is a set of protocols that optimizes standard TCP/IP/HTTP/HTML protocols, for use under the low bandwidth, high latency conditions often found in wireless networks. But, end-to-end security is not supported unless a WAP gateway is operated by the content provider. We propose ITLS mechanism to solve the WAP security problem. The goal of ITLS is to prohibit the WAP gateway from having the pla...

With the advance of wearable devices, an IoT (Internet of Things) gateway should support the efficient forwarding, processing, and provisioning of the streaming data obtained from them. We propose a semantically enriched IoT gateway working on a smartphone for wearable devices. The proposed gateway supports (a) an efficient consolidation and compression of heterogeneous streaming sensor data, (...
