OEE-AODV – Optimized Energy Efficient Routing Protocol for Reliable Data Transmission in FANETS

Abstract FANETs are the new means of communication and have been aiding domestic and military applications for a long time now. FANETS are supported by UAV (Unmanned Autonomous Vehicles) which carry out the task of transmitting and receiving data. FANETs are still susceptible to challenges and issues that ad hoc networks usually face. Because of the lack of infrastructure, FANET related issues need to be addressed before applying any strategies or protocols over the network. Routing and effective transmission are two major challenges faced in FANETs. This objective of a FANET is not aided in any way by the high mobile AUVs in the network scenario. Packet loss and routing failures are common occurrences in a FANET. Node and route links are not permanent and may lead to a lot of transmission related issues. The performance of any network is gauged by its successful delivery rate. Effective delivery is made possible by carefully planned routing strategies. Setting up an optimal path right from the originating source to the delivery address is quite the challenge in a FANET. FANETs also fall victim to various network attacks, primary of which is the black hole attack. Black hole attacks are more common in a FANET and this is closely associated with the AUVs’ high mobility. Data may be completely lost during a black hole attack. Our proposed protocol will address the challenge of effective routing while addressing black hole attacks. Our Eagle optimized Energy Efficient Ad hoc On demand Distance Vector (OEE-AODV)routing protocol focuses primarily on selecting an optimized and secure route towards the destination node .Network factors like trust degree, priority queue, network delay, hop count and the level of energy consumption are taken into consideration in formulating a routing strategy for the proposed protocol. The outcome is an efficient routing strategy that can oversee the successful delivery of the data. The proposed protocol works in two phases. In the first phase, it focuses on setting up an optimal route with select nodes, while in the second phase it enhances the security level of the network by foiling potential black hole attacks with the use of the RREP packets. The nodes along the discovered route will be made up of nodes which are scrutinized and determined as trusted nodes. The OEE-AODV protocol assures the successful delivery of data with the help of an optimal and trusted routing path. The proposed OEE-AODV protocol is assessed against AODV and AODV-V2 protocols to assess its performance. OEE-AODV achieves maximum PDR and throughput while conserving the network energy by minimizing the network delay.
