Abstract
applications, such as: recognition, surveillance, search and rescue operations, and data transmission. FANET consisted of a group of autonomous Unmanned Aerial Vehicles (UAVs) that communicate with each other to form a self-organizing network. This network can be operated only or with traditional communication infrastructure. Many advantages can be offered by Flying Ad-Hoc Networks (FANETs) are an emerging field with significant potential for various FANET, such as: scalability, mobility, low cost of deployment and maintenance, increased flexibility in terms of network metrics which makes them ideal for applications that require rapid deployment and reconfiguration. However, the performance of FANET is related to UAV queue size which have a significant impact on data transmission quality.
In this project, we have reviewed and discussed several studies at Mac layer level in FANET which ensure efficient and fair transmission of data. an overview was provided of MAC layer queue and algorithms which used to manage the data transmission. Moreover, we have provided our proposed conceptual model of the queue size effect on data transmission in FANET. Furthermore, we have evaluated the network performances in function of queue size in terms of various metrics, such as: delay, throughput, and Packet Delivery Ratio (PDR).The simulation results using NS2 show that when the queue size is too small, the throughput and PDR decreased due to congestion problem, and the delay increased. On the other hand, when the queue size is too large, the delay increased and the throughput and PDR increased.
In resume, the results of this project showed that the change of queue size can affect significatively the data transmission quality in FANET
