Abstract: - The recent technology development increases the opportunity to create valuable network services to user. Flying ad-hoc networks (FANET) in one among them which evolved recently with enhanced value added services with common features similar to its predecessor ad-hoc networks like vehicular ad hoc networks (VANET) and mobile ad hoc networks (MANET). Due to its distinctive features FANETs are widely preferred in recent telecommunication services which requires high quality of services, efficiency, environment adaptability and scalability. In order to achieve high efficiency multiple aerial vehicles are used in general architectures. The Communication in such vehicles are progressed directly between the nodes or through relay nodes. Routing is an important process to establish a connection link between the nodes in the architecture. This research work proposed a routing strategy suitable for dynamic and static environments as a hybrid optimization model which reduces the issues in link establishment. Nature inspired bee colony optimization is used along with conventional routing algorithms such as optimized link state routing protocol and Dynamic Source Routing Protocol to improve the link discovery. The proposed optimized routing outperforms well in reduced delay and communication overhead of the network. Keywords: - Flying Ad hoc Networks, Routing, Active and Reactive topology. 1. Introduction Mobile ad hoc networks (MANETs) are widely used in various applications and it is further expanded into Flying ad hoc networks (FANETs) as an improved version which uses flying machine for transmission and reception in wireless communication. The advantages of FANETs is its easy setup and wireless communication realization in anyplace. It has multi-hop, self-organizing, self-healing characteristics similar to its predecessor MANET. Using small group of flying vehicles this network could be deployed rapidly and the nodes are coordinated from the ground which gives high degree of freedom compared to any other networks. Unmanned aerial vehicle network is discussed earlier to bring this effective flying ad hoc networks. This flying networks helpful in complex situations where the conventional network could not be established due to natural calamities. The wide range of applications of FANETs will be disaster management, rescue operations, security and other location aware services. Earlier single aerial vehicle network based systems are evolved, but these systems have lagged performance due to its network scalability and limited capability operations. These makes the system inflexible and non-adoptable for wide range of applications. Later multi-layer aerial vehicle networks are evolved to reduce the issues in single aerial vehicle networks and this is termed as flying ad hoc networks. Due to tis infrastructure less network characteristics it doesn’t require any central control system and its swarms themselves in air and arrange a wireless network. Without any centralized system the elements in the network communicates with each other and also to the base station which is an added advantage in flying ad hoc networks. FANETs are widely used in various applications like calamity administration, location aware services, sensor networks, Military services and other rescue operations. Figure 1 gives an illustration of flying ad hoc networks in detail.
