Advances in technology are not only changing the world around us but also driving the wireless industry to develop the next generation of network technology. There is a lot of buzz building over the advent of 5G that will facilitate the entire planet through continuous and ubiquitous communication connecting anybody to anything, anywhere, anytime, and anyhow regardless of the device, service, network, or geographical existence. 5G will also prove to be a paradigm shift including high carrier frequencies with massive bandwidths, having a large number of antennas, and with an extreme base station and device densities. In this paper, we investigate the potential beneficiaries of 5G and identify the use-cases, where 5G can make an impact. In particular, we consider three main use-cases: vehicle-to-everything (V2X) communication, drones, and healthcare. We explore and highlight the problems and deficiencies of current cellular technologies with respect to these use-cases and identify how 5G will overcome those deficiencies. We also identified the open research problems and provide possible future directions to cope with those issues. 5G, V2X communication, drones, healthcare, ultra-low-latency, ultra-high-reliability.

Wireless sensor networks (WSNs) can be widely used for managing various scenarios existing in social, industrial and numerous environmental management systems. They have been widely used in environmental monitoring and management applications and have also found application in disaster management scenarios. One of the greatest problems faced by the scientific community in organizing data collection through sensor networks in areas of disaster is the disorder and destruction brought about in the communication systems prevailing in such situations. In this paper, a scientific study of the various scenarios that could occur post-disaster and the various housekeeping functions each sensor node would adopt as part of the self management requirement is provided. We also present a sensor task management framework that could be implemented to provide a low energy consuming, reliable network for WSNs deployed for critical infrastructure management.Keywords: self-managed wireless sensor cloud, critical event management. Related WorkWireless sensor networks used for monitoring applications can be prone to various events like nodes dying, topology reconfiguration, loss of connection to the base station etc. Depending on various events that could occur during a WSN deployment, elements that could be said to contribute to the design of a WSN are protocols, data fusion / aggregation techniques, topology management and methods of deployment. Protocols that are used in WSNs can be categorized as network / routing, transport and MAC protocols. There have been several network protocols designed to address the issue of connectivity establishment. According to the authors of [1], LEACH
