MDRMA: Multi-data rate mobility-aware AODV-based protocol for flying ad-hoc networks

The most recent decade has seen a developing enthusiasm for the utilization of Unmanned Aerial Vehicles (UAVs) for different services and applications. UAVs, or as known as drones, have appeared to be productive in finishing complex errands when sorted out as ad hoc connected groups, thereby bringing into existence a Flying Ad hoc Network (FANET). Owing to its specific characteristics such as high mobility, rapid topology changes, and frequent link failures, FANETs bring further challenges into these networks. Therefore, developing an efficient routing protocol over FANETs is a very challenging matter and consequently triggered the attention of a lot of current researchers. In this article, the authors propose a Multi Data Rate Mobility Aware (MDRMA) protocol in which novel routing and power controlled mechanisms have been suggested. Basically, MDRMA protocol is considered as a major extension of Mobility Aware Dual Phase Ad-hoc on-demand Distance Vector with Adaptive Hello Messages (MA-DP-AODV-AHM) protocol. Particularly, in MDRMA-Routing algorithm, the establishment of routes is not arbitrarily but rather is conditioned upon the achievement of certain requirements which can be extracted from the positive answers of the questions follow. Is that intermediate UAV able of affording the possible transmission rate requested by the source UAV? Are the transmitting and receiving UAVs not thrifting away from each other? Does the speed of that intermediate UAV not exceed a certain threshold? Upon the efficient deal of prior concerns, MDRM-Routing algorithm guarantees establishing stable routes with fast data forwarding wireless links. Not only to this extent, MDRMA-Power controlled algorithm also adds some modifications on 802.11b standard, explicitly on RTS/CTS collision avoidance technique, to maintain the minimum transmission power required by a transmitting UAV for a successful reception of packets at target UAV and at a desired data transmission rate bearing in mind the receiver sensitivity and signal-to-interference-noise ratio threshold, thereby enforcing fast data forwarding. The performance of the authors' protocol has been evaluated in the perspectives of end-to-end delay, control overhead, and packet delivery ratio using NS3 simulator in which enormous simulations have been conducted under the base of UAVs' density, packet rate and constant bit rate connections. Simulation results summarize that MDRMA contributes efficiently in mitigating the network instability through generating fast and stable routes and reducing link failures. MDRMA has proved further its superiority over MA-DP-AODV-AHM protocol.
