“…In the application of search and rescue, navigation with collision avoidance is important for both ground and FRs. Approaches such as [ 81 , 83 , 84 , 106 ] and some others such as [ 107 , 108 , 109 , 110 ] have proposed various path planning and reactive navigation algorithms. Although some of them are designed for FRs, such as [ 107 , 108 , 109 ], a fixed altitude is assumed; while few papers studied the much more difficult case of collision-free 3D navigation [ 111 , 112 , 113 , 114 , 115 ].…”

“…With this regard, there is a necessity to extend the available 2D methods to the 3D scenario. Furthermore, 3D risk-aware navigation is more preferred to avoid no-flight areas, such as populated areas and those with chemical plants [ 107 , 108 , 109 ]. Risk-aware navigation especially suits urban environments, where a relatively larger number of obstacles and no-flight areas exist.…”

The Internet of Flying Robots (IoFR) has received much attention in recent years thanks to the mobility and flexibility of flying robots. Although a lot of research has been done, there is a lack of a comprehensive survey on this topic. This paper analyzes several typical problems in designing IoFR for real applications, including wireless communication support, monitoring targets of interest, serving a wireless sensor network, and collaborating with ground robots. In particular, an overview of the existing publications on the coverage problem, connectivity of flying robots, energy capacity limitation, target searching, path planning, flying robot navigation with collision avoidance, etc., is presented. Beyond the discussion of these available approaches, some shortcomings of them are indicated and some promising future research directions are pointed out.

“…3,5,6 In view of the point that ABSs are easy to deploy, capable of reprogramming during run time, measuring anything anywhere, and having high mobility, they can be chosen to provide many applications such as service delivery, farming, pollution mitigation, and rescue operations. 3,7,8 Moreover, ABSs are an efficient option to be chosen for IoT networks. 9,10 At the same time, they can provide extra services when they are equipped with some special devices (eg, cameras, actuators, and sensors).…”

“…9,10 At the same time, they can provide extra services when they are equipped with some special devices (eg, cameras, actuators, and sensors). 3,7,8 In addition, ABSs can update their locations based on the new locations of IoT users. Therefore, ABSs can collect IoT data from the IoT users and transmit it to other devices that are out of transmission range playing an important role in IoT networks which have battery-limited devices.…”

In this paper, a novel method for joint resource allocation, three-dimensional placement, and user association as a predominant problem in the internet of things (IoTs) networks is proposed. We consider two kinds of channel models for the links between users and aerial base stations (ABSs), namely (a) line of sight (LoS) model and (b) generalized model. In the LoS case, all the ABSs should establish LoS communications path toward IoT users. In the generalized case, the ABSs channels toward the IoT users could be LoS or nonline of sight. We propose four different scenarios, namely interference-free (IF)-LoS, IF-Generalized, interference-included (II)-LoS, and II-Generalized. The IF-LoS and IF-Generalized cases consider subcarrier and modulation order as the resources while the II-LoS and II-Generalized cases consider transmit power, subcarrier, and modulation order as the resources. Our objective function is minimizing the overall transmit power of the IoT users while satisfying some quality of service constraints in the uplink. To solve the resulting nonconvex optimization problem, we convert the main problem with high complexity into the subproblems with low complexities. We compare the performance of our joint proposed scenario with other joint and disjoint cases for the IF-LoS, IF-Generalized, II-LoS, and II-Generalized cases. Moreover, we evaluate the performance of the proposed schemes for different numbers of ABSs, environment types, target areas, and numbers of IoT users.Trans Emerging Tel Tech. 2019;30:e3632.wileyonlinelibrary.com/journal/ett

“…As effective means, the millimeterwave and beamforming techniques [20] can also be adopted within the UAV-based networks [15]. Furthermore, a multiobjective path planning framework to explore a suitable path for a UAV operating in a dynamic urban environment was proposed by Yin et al in [16].…”
