<p>In Flying Ad-hoc Networks (FANET), the communication among nodes is carried out in a fast-moving dynamic topology. Over the past few decades, FANETs are found to be applicable in plenty of domains i.e., Military battlefield, surveillance, healthcare, transportation, etc. In FANET, unmanned aerial vehicles (UAVs) help exchange real-time information among different entities and control stations. Due to the complex infrastructure and rapid mobility, routing in these networks becomes quite challenging. To deal with such challenges, the selection of appropriate routing algorithm according to the requirements of specific situations is essential. Routing algorithms are generally categorized into two main categories viz. proactive and reactive. In dynamic situations like FANET, proactive routing provides up-to-date routing information. Keeping in view of several advantages of proactive routing protocols, here, the performance of two well-known proactive routing algorithms viz. Destination Sequenced Distance Vector Routing (DSDV) and Optimized Link State Routing (OLSR), is examined under group mobility model scenario for FANET environment. Empirical evaluation of the scenario is carried by conducting a series of experiments under varying traffic sources patterns i.e., speed, network load, groups, and number of UAVs. Based on several performance parameters, including packet loss, routing overhead, normalized routing load, packet delivery fraction, throughput, and average one-way delay, a performance assessment of OLSR and DSDV is evaluated for FANETs. Simulation results showed that DSDV is more suitable for FANET environments under group mobility model for FANET environment.</p>
