The use of GIS (Geographic Information Systems) technologies has become a very common tool in multiple research fields. These applications are currently applied to different areas of knowledge such as the environment, seismic vulnerability, hydrology and climate, agriculture, urban planning, economics, sociology, telecommunications, etc. This special issue seeks to collect a significant catalog of the current state of the subject with relevant case studies or innovative approaches related to GIS technologies. The special issue arises from a multidisciplinary perspective, not closed to any field of knowledge.

Many emerging network applications exhibit intermittent connectivity, changes in topology with no guarantee that a fully connected path between source and destination exists at any time. This resulted in rendering the traditional routing protocols inadequate to deliver messages between hosts. Since the connectivity between the source and the destination in most mobile and DTNs network is not guarantee, the security requirements through authentication and reliable routing system will be challenging to establish. This has opened new challenges for routing in mobile and DTNs.

As a dominant technology in our daily life, IoT promises a smart and pervasive computing landscape in which a huge variety of devices and sensors are linked together. In the majority of applications, IoT-based devices/sensors need to be in continuous interaction with their environments, with each other, or with the IoT cloud. This exponentially increases the communication volume which highly drains the energy of battery and shortens the device-lifetime. Even though great efforts have been exerted in this domain, scalable and novel solutions are still required as the technology is rapidly evolved.

There has been a lot of progress in the field of IoT. Smart sensors technology combined with internet of things can be a big leap in the field of data communication. Application of this technique ranges from security management to environmental monitoring, agriculture and even smart house and cities. However, the long-term operation of such sensors has created an issue as designing of low power sensor is complex.

In recent years, through the wide expansion of multiprocessor system-on-chips (MPoCs) and multi/many-core architecture, hundreds of processing cores on a single chip are simultaneously working toghether. Network-on-Chip (NoC) approach has been considered as an efficient communication paradigm which can be appropriately replaced by the traditional bus interconnect. Some interesting features of NoC such as scalable infrastructure and modularity, high communication bandwidth, improved power dissipation and network latency convince the system designers to widely exploit NoC structure instead of bus-based or point-to-point on-chip communication platforms.

In recent years, wireless and mobile communication systems have become increasingly popular as an inexpensive and promising means for ubiquitous communications. As for this scenario, the QoS provisioning and the management of network security have become crucial tasks to determine the success of future generation wireless mobile networks. Besides, the energy efficiency is still of great importance for the mobile divice. Finally, the applications of mobile networks, such as mobile crowd sensing, fog computing, etc. bring in the risk of leaking users' privacy.

Today’s telecommunication networks have become complex interacting systems which involve cloud operations, core and metro transport, mobile connectivity, and video streaming. The Optical Networks (OTNs) are regarded as the cornerstone of the modern society since such networks can provision large capacity required by the enormous amount of heterogeneous data at low costs.
