How Mobile Devices are Transforming Disaster Relief and Public Safety
With its growing usage, mobile technology is greatly improving disaster relief and public safety efforts. Countries around the world face threats from natural disasters, climate change, civil unrest, terrorist attacks, and criminal activities, among others. Mobile devices, tablets, and smart phones enable emergency providers and the general public to manage these challenges and mitigate public safety concerns.In this paper, part of the Brookings Mobile Economy Project, we focus on how mobile technology provides an early warning system, aids in emergency coordination, and improves public communications. In particular, we review how mobile devices assist with public safety, disaster planning, and crisis response. We explain how these devices are instrumental in the design and functioning of integrated, multi-layered communications networks. We demonstrate how they have helped save lives and ameliorate human suffering throughout the world
UAV-Empowered Disaster-Resilient Edge Architecture for Delay-Sensitive Communication
The fifth-generation (5G) communication systems will enable enhanced mobile
broadband, ultra-reliable low latency, and massive connectivity services. The
broadband and low-latency services are indispensable to public safety (PS)
communication during natural or man-made disasters. Recently, the third
generation partnership project long term evolution (3GPPLTE) has emerged as a
promising candidate to enable broadband PS communications. In this article,
first we present six major PS-LTE enabling services and the current status of
PS-LTE in 3GPP releases. Then, we discuss the spectrum bands allocated for
PS-LTE in major countries by international telecommunication union (ITU).
Finally, we propose a disaster resilient three-layered architecture for PS-LTE
(DR-PSLTE). This architecture consists of a software-defined network (SDN)
layer to provide centralized control, an unmanned air vehicle (UAV) cloudlet
layer to facilitate edge computing or to enable emergency communication link,
and a radio access layer. The proposed architecture is flexible and combines
the benefits of SDNs and edge computing to efficiently meet the delay
requirements of various PS-LTE services. Numerical results verified that under
the proposed DR-PSLTE architecture, delay is reduced by 20% as compared with
the conventional centralized computing architecture.Comment: 9,
Mobile Broadband Possibilities considering the Arrival of IEEE 802.16m & LTE with an Emphasis on South Asia
This paper intends to look deeper into finding an ideal mobile broadband
solution. Special stress has been put in the South Asian region through some
comparative analysis. Proving their competency in numerous aspects, WiMAX and
LTE already have already made a strong position in telecommunication industry.
Both WiMAX and LTE are 4G technologies designed to move data rather than voice
having IP networks based on OFDM technology. So, they aren't like typical
technological rivals as of GSM and CDMA. But still a gesture of hostility seems
to outburst long before the stable commercial launch of LTE. In this paper
various aspects of WiMAX and LTE for deployment have been analyzed. Again, we
tried to make every possible consideration with respect to south Asia i.e. how
mass people of this region may be benefited. As a result, it might be regarded
as a good source in case of making major BWA deployment decisions in this
region. Besides these, it also opens the path for further research and in depth
thinking in this issue.Comment: IEEE Publication format, ISSN 1947 5500,

Physics-Based Swarm Intelligence for Disaster Relief Communications
This study explores how a swarm of aerial mobile vehicles can provide network
connectivity and meet the stringent requirements of public protection and
disaster relief operations. In this context, we design a physics-based
controlled mobility strategy, which we name the extended Virtual Force Protocol
(VFPe), allowing self-propelled nodes, and in particular here unmanned aerial
vehicles, to fly autonomously and cooperatively. In this way, ground devices
scattered on the operation site may establish communications through the
wireless multi-hop communication routes formed by the network of aerial nodes.
We further investigate through simulations the behavior of the VFPe protocol,
notably focusing on the way node location information is disseminated into the
network as well as on the impact of the number of exploration nodes on the
overall network performance.Comment: in International Conference on Ad Hoc Networks and Wireless, Jul
