Low Power Wide Area Networks (LPWAN) are becoming the powerful communication technologies of IoT tomorrow. LoRaWAN, SigFox, and NB-IoT three competing LPWAN technologies. On other hand, Smart Water Grid (SWG) is an emerging paradigm that promises to over come issues such as pipes leaks encountered by current water infrastructure deploying smart devices into for monitoring purposes. This paper firstly explores physical features above provides a comprehensive comparison between them well their...
Network slicing emerges as a key technology in next generation networks, boosted by the integration of software‐defined networking and network functions virtualization. However, while allowing resource sharing among multiple tenants, such networks must also ensure security requirements needed for scenarios they are employed. This letter presents leading challenges on use slices at packet core, solutions that academy industry proposing to address them, pointing out some directions should be...
Heating appliances consume approximately 48 % of the energy spent on household every year. Furthermore, a malfunctioning device can increase cost even further. Thus, there is need to create methods that identify equipment’s malfunctions and eventual failures before they occur. This only possible with combination data acquisition, analysis prediction/forecast. paper presents an infrastructure supports previously mentioned capabilities was deployed for failure detection in boilers, making...
As the largest radio telescope in world, Square Kilometre Array (SKA) will lead next generation of astronomy. The feats engineering required to construct array be matched only by techniques developed exploit rich scientific value data. To drive forward development efficient and accurate analysis methods, we are designing a series data challenges that provide community with high-quality datasets for testing evaluating new techniques. In this paper present description results from first such...
Abstract The advances on recent communication paradigms brings new security and privacy challenges, mainly about personal data collection by smart devices. Resource constrained devices face serious issues to run complex cryptographic algorithms. Trying evaluate the performance impact of those algorithms in usual common used homes, this paper we tested different low computational devices, typically applied testing configurations using two most transport protocols (HTTP MQTT). experiment...
Network operators are under pressure to offer efficient network-based services while keeping service deployment costs a minimum. functions virtualization (NFV) can potentially revolutionize bringing low-deployment for network operators. The NFV has been introduced ultimately extend the non-proprietary and open-standard-based model deployments, significant improvements today's proprietary locked implementations. Notwithstanding continuous efforts of both academia industry support paradigm,...
An expansion of services and unprecedented traffic growth is anticipated in future networks, aligned with the adoption long-awaited Fifth Generation (5G) mobile communications. To support this demand, without exposing operators to pressure CAPEX OPEX, 5G uses new frequency bands, adopts promising trends, including: densification, softwarization, autonomous management. While first technology proposed handle requirements, softwarization management are expected play, synergy, ensure desired...
Low Power Wide Area Networks (LPWANs) are becoming the most suitable communication technologies in Internet of Things (IoT) applications due to their low power consumption, long range and cost.Currently, Long Range Network (LoRaWAN) is one popular LPWANs.Because it offers possibility build private networks with an open standard, LoRaWAN deployed LPWAN solution.However, supports only one-hop communication, that is, end-devices connected directly gateways.Since LoRa links can be kilometers...

The fourth generation (4G) network paradigm has long been sought. A user-centric vision for such "always best connected" next-generation 4G networks is neighborhood wireless mesh (WMNs). In this context, the formation of WMNs reflects trade-off between immediate self-interest user, and user's need social contacts. Notably, users would be required to pool their resources in order support creation operation underlying communication (participating at all physical, access, layers), but also...
