Stable and reliable communication is essential in disaster scenarios. Mobile Ad hoc Networks (MANETs) provide a network that is fast to setup and that works independently of possibly damaged infrastructure. This is important during disaster rescue and recovery missions. But single isolated MANETs are able to cover only a limited area. Therefore, it is necessary to interconnect these individual networks in order to provide communication throughout the whole disaster area. The resulting network is heterogeneous because each MANET might employ different routing protocols as well as other underlying network technologies. In this paper, we present an approach to couple such heterogeneous networks using multihomed border nodes. We show how network-wide route discovery and name resolution is achieved and also propose a solution to address possible collisions in such environments.

The framework assumes that Boundary Nodes are used to connect MANETS and drones that are deployed as data ferries using different protocols.…”

In recent years, Unmanned Aerial Vehicles (UAVs) have gained significant interest in research groups due to the wide range of applications, such as disaster surveillance and monitoring, rescue operations, military, civil, and so forth. UAVs are most often used to fulfill both user's services and requirements such as wireless communication facilities to end-users, as a relay node to extend the coverage of the core network, and so forth. UAVs are versatile in design and can cover larger areas, contrary to the Tethered Balloon and Loon Balloon systems. Generally in any natural or humanmade disaster, there is a high potential risk of damage to buildings, transport systems, communication systems, and basic services. During heavy disasters like landslides, forest fires, floods, earthquakes, and so forth, the conventional terrestrial communication system gets destroyed, and people face many problems. In this case, UAVs prove to offer a better solution to provide fast, cost-effective, easy to deploy, and secure wireless communication to the victims. But there are some issues like interference between UAVs and other base stations, coordination between UAVs, Quality of Service requirements, Size, Weight, and Power limitation, delay, coverage, positioning of UAVs, and so forth. This study article mainly highlighted these issues and try to present the recent developments of the state-of-the-art to overcome these issues. In UAV communications, with an increasing emphasis on how UAVs can be integrated with different technologies, such as the Internet of Things, Wireless Sensor Network, Heterogeneous Network, and Cloud computing. The primary aim of this article is to examine how UAVs can assist survivors in floods, earthquakes, tsunamis, or in any natural or human-made disaster situations, either in the present or soon. Also, it focused on various applications of UAVs in disaster management (DM). It underlines the significance of UAVs in DM and their advantages. It also focuses on the various issues and challenges faced by the UAV-based infrastructure and security issues and gives future directions.

“…OppNets therefore provide economical, infrastructure-less and mobile communication that involves delay-tolerant information. OppNets have been envisioned for advertisements in the form of digital word-of-mouth services, recommendation and opportunistic trading [1][2][3], as well as communication in the aftermath of large-scale disasters [4][5][6]. The following section presents another envisioned application of OppNets towards realizing smart cities.…”

Collecting Sensed Data with Opportunistic Networks: The Case of Contact Information Overhead

et al. 2017

Abstract:The rising human population in urban environments drives the mission towards smart cities, which envisions a wide deployment of sensors in order to improve the quality of living. In this regard, opportunistic networks (OppNets) present an economical means of collecting delay tolerant data from sensors to their respective gateways for providing various Smart City services. Due to the distributed nature of the network, encounter-based routing protocols achieve acceptable throughput by requiring nodes to exchange and update contact information on an encounter basis. Unfortunately, sufficient insight into the associated overhead is lacking in the literature. Hence, we contribute by modelling contact information overhead and investigating its impact on OppNet routing, particularly in terms of data exchange success and energy consumption on portable handheld devices. Our findings reveal that the expected contact information overhead in Smart City scenarios significantly reduces data exchange success and increases energy consumption on portable handheld devices, thereby threatening the feasibility of the technology. We address this issue by proposing an algorithm that can be incorporated into encounter-based routing protocols to reduce contact information overhead without compromising throughput. Simulation results show that our proposed algorithm reduces the average contact information overhead, increases throughput and reduces average energy consumption.
