Dear Colleagues,

The development and deployment of several wireless networks mean that mobile devices will have several wireless interfaces including 3G, WLAN, WiMAX and LTE. This represents a significant development as users will want to be always connected from anywhere and at any time. This will be achieved using vertical handover techniques where connections will be seamlessly switched between available networks.

However, these heterogeneous environments raise many issues in terms of Quality-of-Service (QoS) and Security as different wireless networks may display huge disparities with regard to these two major network properties. These differences become serious problems in heterogeneous environments as mobile nodes need to quickly adapt while moving from one network to another.  This Special Issue looks at the design, development, implementation and evaluation of mechanisms to manage Quality-of-Service and Security in mobile heterogeneous environments.

Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Future Internet is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 500 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Title: Human Directed Quality of Service in Networked Cyber-Physical Systems

Abstract: As we integrate wired and wireless networks, together with distributed decision nodes and fast decision algorithms into critical Cyber-Physical-Human Systems, the issue of quality of service (QoS) shifts from the technological to the human domain. This paper examines this issue in the context of Emergency Management systems (EMS) are important and complex examples of Cyber-Physical-Human systems that are deployed so as to optimise the outcome of an emergency from a human perspective. They use sensor networks, networked decision nodes and communications with evacuees and first responders to optimise the overall QoS to benefit primarily human beings in terms of survival, health and safety, and the protection of nature, property and valuable infrastructures. The use of technology for emergency management also has side effects in terms of failures and malicious attacks of the ICT system, so the outcome will be affected by how well the ICT system operates under stress. Thus this paper surveys research on wireless sensor-assisted EMS, including networking, distributed control, and knowledge discovery. In addition, a simulated evaluation of increased effectiveness and liabilities that wireless communications introduce is conducted when adversaries exacerbate the emergency by malicious attacks through the wireless system.
