Special Issue Information

Dear Colleagues,

Mobile communication systems have been progressively adopted and popularized within the last decade, becoming an essential element for domestic, industrial and administrative environments and applications. The evolution of communication systems is leading towards higher degrees of interactivity, provided by user centric systems, in which wide connectivity, within the framework of IoT and the use of Heterogeneous Network will enable Context Aware environments, such as those provided for Ambient Assisted Living or Smart Cities/Smart Regions.

This Special Issue focuses on the developments and evolution of wireless communication systems towards the progressive implementation of Context Aware environments and applications.

Potential topics include, but are not limited to:

  • Context Aware scenarios and testbeds
  • Mobile oriented applications towards Context Aware environments
  • Case studies within AAL, Home Automation, Building Automation
  • Collaborative/HetNet Communication Paradigms
  • Implementation of Mobile Applications of Smart Cities/Smart Regions
  • Solutions within Vehicular Networks/Intelligent Transportation Systems integrated within Context Aware environments
  • Security and Privacy issues within Context Aware Mobile Systems

Manuscripts should be submitted online at by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short 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 thoroughly refereed through a single-blind 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 monthly 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 1600 CHF (Swiss Francs).

Due to the spectrum varying nature of cognitive radio networks, secondary users are required to perform spectrum handoffs when the spectrum is occupied by primary users, which will lead to a handoff delay. In this paper, based on the multi-armed bandit framework of medium access in decentralized cognitive radio networks, we investigate blind spectrum selection problem of secondary users whose sensing ability of cognitive radio is limited and the channel statistics are a priori unknown, taking the handoff delay as a fixed handoff cost into consideration. In this scenario, secondary users have to make the choice of either staying foregoing spectrum with low availability or handing off to another spectrum with higher availability. We model the problem and investigate the performance of three representative policies, i.e., ρPRE, SL(K), kth-UCB1. The simulation results show that, despite the inclusion of the fixed handoff cost, these policies achieve the same asymptotic performance as that without handoff cost. Moreover, through comparison of these policies, we found the kth-UCB1 policy has better overall performance. Full article
