Opportunistic Networks in Urban Environment

Dear Colleagues,

Urban environments are becoming a vibrant application domain for information and communication technologies (ICT). In fact, ICT solutions are being adopted as a catalyst in the smart-city domain, on top of which new services are developed and legacy ones evolve. The coming of such services will lead to a remarkable increase of the communication capacity domain, along with specific service-dependent requirements. In order to cope with such demand, future urban wireless scenarios will embrace multiple technologies, and a remarkably higher density of communications devices. Such devices will be operated in a coordinated manner to optimize the potential of communication capacity in an efficient way.

In this sense, opportunistic networking is believed to play a relevant role in such complex scenarios, since it can leverage not only communication capabilities of access elements, but also of other devices. In the last years, we have witnessed the appearance of new opportunistic communication technologies aimed to cope with new urban services, such as IoT or V2X. In addition, novel networking techniques are being proposed to increase the communication efficiency.

This Special Issue aims to gather original studies on opportunistic networking in urban environments, innovative proposal of network techniques considering novel technologies, solutions to coordinate dense urban scenarios, and exploitation of opportunistic solutions to create novel urban services. Relevant topics of interest include, but are not limited to:

• Novel network topologies urban environments
• Device-to-device communications
• Opportunistic networking for IoT and machine-to-machine communications
• Integration of opportunistic and cellular networks
• Energy aware techniques for ad-hoc urban networks
• Coding techniques in opportunistic wireless networks
• Advanced routing techniques
• Radio resource optimization techniques
• Urban services over opportunistic networks

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com 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 250 words) can be sent to the Editorial Office for assessment.

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 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
