Managing Quality-of-Service and Security in Mobile Heterogeneous Environments

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.
