“…The motivation of this paper comes from the works [30], [31], where the Poisson-Delaunay triangulation was exploited to model the 2D cellular networks for terrestrial UEs. A similar idea is employed in this paper to provide service for aerial UAVs, which benefits by maximizing the use of existing cellular network infrastructure and providing reliable communication connectivity for UAVs, in addition to terrestrial UEs.…”

This paper designs a novel ground-to-air communication scheme to serve unmanned aerial vehicles (UAVs) through legacy terrestrial base stations (BSs). In particular, a tractable coordinated multi-point (CoMP) transmission based on the geometry of Poisson-Delaunay triangulation is developed, which provides reliable and seamless connectivity for UAVs. An effective dynamic frequency allocation scheme is designed to eliminate inter-cell interference by using the theory of circle packing. For exact performance evaluation, the handoff probability of a typical UAV is characterized, and then the coverage probability with handoffs is attained. Simulation and numerical results corroborate that the proposed scheme outperforms the conventional CoMP scheme with three nearest cooperating BSs in terms of handoff and coverage probabilities. Moreover, as each UAV has a fixed and unique CoMP BS set, it avoids the realtime dynamic BS searching process, thus reducing the feedback overhead.

“…The work of [ 14 ] studies the control plane protocols for cooperative communications and proposes a novel coordination architecture to enhance the performance of multi-cell cooperative cellular networks. The study of [ 15 ] proposes a Poisson-Delaunay-triangulation-based method to allow the cooperating BS set of the user equipment (UE) to be fixed and off-line as determined by the BSs’ location information. The research of [ 16 ] proposes a deep-learning-based scheme to enhance the throughput of the DL CoMP in heterogeneous 5G NR networks.…”

“…If the resource of one cell is not sufficient, we perform offloading by transmitting edge UEs to the neighboring cells with DCS. Previous works apply a fixed cooperating set [ 15 ]. Though these methods are easy to work with, they are not flexible and also cannot adjust the set to fit a real traffic scenario.…”

Coordinated Multi-Point (CoMP) is an important technique in B4G/5G networks. With CoMP, multiple base stations can be clustered to compose a cooperating set to improve system throughput, especially for the users in cell edges. Existed studies have discussed how to mitigate overloading scenarios and enhance system throughput with CoMP statically. However, static cooperation fixes the set size and neglects the fast-changing of B4G/5G networks. Thus, this paper provides a full study of off-peak hours and overloading scenarios. During off-peak hours, we propose to reduce BSs’ transmission power and use the free radio resource to save energy while guaranteeing users’ QoS. In addition, if large-scale activities happen with crowds gathering or in peak hours, we dynamically compose the cooperating set based on instant traffic requests to adjust base stations’ BSs’ transmission power; thus, the system will efficiently offload the traffic to the member cells which have available radio resources in the cooperating set. Experimental results show that the proposed schemes enhance system throughput, radio resource utilization, and energy efficiency, compared to other existing schemes.

“…In this type of Voronoi diagrams, a Euclidean distance is the only parameter in generating the Voronoi regions. These diagrams were generated in MATLAB software (2013) base on The ''Delaunay Triangulation'' method (Chai et al, 2020;Li et al, 2020;Shankar et al, 2020). The Delaunay triangulation of a discrete point set P in general positions corresponds to the dual graphs of the Voronoi diagrams for P. The circumcenters of Delaunay triangles are the vertices of the Voronoi diagram.…”

The trend of engineering has been towards modern innovation in designs by maintaining not only the esthetic point of view but also stability and efficiency. In this regard, in this study, one of the nature-inspired structures, Voronoi tessellation, is introduced and applied as a structural configuration in the design of beams. Thus, various models of beams built with Voronoi diagrams are considered. To this end, first, the rules and regulations which govern the structure of Voronoi tessellation will be presented. Then various stages of generating the geometry of Voronoi beams will be described in detail. Considering the logical architectural requirements, the presented models are prepared as 2D-beams with different degrees of uniformity comprising the minimum and maximum Voronoi cells, which will be designed according to guidelines. In the next step, uniform loading under different boundary conditions will be applied to all Voronoi beams, and the results including structural weight, maximum displacement, and load-bearing capacity will be presented. The results of beams designed with Voronoi structures reveal that increasing the size of minimum cell will result in the rise of the maximum displacements as well as load-to-weight ratios and considerably reduce the weight of Voronoi beams but demonstrate sufficient load-bearing capacity. It also proves that as the non-uniformity of cells increases, displacements will grow. In addition, although the weight of samples will reduce, the load-to-weight ratios of the archetypes remain almost constant. Placing more supports for these structures will lead to an improvement in all aspects of design, especially on the response of beams with large spans.
