Theoretical analysis of interference between directional beams in drone-based 3D mesh network

Abstract

This paper proposes a route optimization scheme for three-dimensional wireless mesh networks implemented by using formation flying of autonomous unmanned aerial vehicles, also known as drones. Inter-drone communication above the ground can achieve free space propagation as obstacles are eliminated. However, transmission efficiency can be degraded due to sneak path interference inside the drone [1].

In this paper, based on formation flight related work [2] suitable for drone communications, we theoretically analyze this interference by directional beams and propose an optimal route selection scheme with high transmission rate.
