Abstract There is a tremendous growth in telecommunication networks due to the emergence of various communication techniques. Optical communications have been the major contributors to it. Free space optical communication (FSO) is a technique based on transmission of data by propagating the light in free space. This is an effective technique to transmit the data at high bit rate over short distance with the added advantage of easy and fast installation and high security. Hybrid RF/FSO technique improve the overall reliability of the system. In this paper, aerial application of the RF/FSO system, i.e., airborne Internet which includes the use of optical links in the network of unmanned aerial vehicles (UAVs) is given. Different formations of UAV swarms, few methods to combat the problems faced by unmanned aerial vehicles (UAVs) and high altitude platform (HAPs) for research work have been discussed. A model is also proposed to improve the reliability of the swarm network.

1 Introduction Since the evolution of mankind has been taken place, communication has become an important way to send and exchange views throughout the world as one of the principal interest of human beings. The information is sent via an electromagnetic carrier wave whose frequency can vary from MHz to THz in a communication system. As we are beginning towards a new era, various dramatic changes in communication have been coming across. For example, businesses today rely on high-speed networks to do their daily affairs [1, 2].

using 155 Mbps are now using 1 Gbps connections. Thus, demand for bandwidth has been increased and at the same time the usage of those technologies which could be cost effective are to be promoted. Free Space Optics is a new technique which is similar to optical fiber infrastructure but no cable is involved [3]. It requires line of sight connectivity between receiver and transmitter with a capability of sending up to 125 Gbps of data, voice, video communication simultaneously through air and even enable WDM like technologies to operate through free space. It has distinct advantages like no license requirement, easily upgradable, immune to RF interference, requires no safety upgrades, can be deployed everywhere, economical [4, 5]. Although FSO is gaining wide market acceptance as a functional wireless, high bandwidth access tool with license free access but still suffers from serious drawbacks. To combat that another thing becoming popular is hybrid FSO [6,
