SIRFRM - Secure and Intelligent Routing Fairness Rate Model for Flying Adhoc Networks

Routing and security are critical considerations when designing a communication network for Flying Adhoc Networks (FANET). However, the rapid topological changes and high mobility of aerial vehicles make it difficult to maintain a stable network. Moreover, cross-layer routing is required, as it makes the best routing decisions by using dependence parameters across protocol layers as routing variables to enhance network efficiency. A Secure and Intelligent Routing Fairness Rate Model (SIRFRM) is proposed for reliable and secure transmission to address these issues. Firstly, the proposed protocol employs a cross-layer methodology to exchange information about routing parameters from the Media Access Control (MAC) layer. The selection for the best routing strategy takes into account a variety of constraints, such as “distance, energy, data transfer rate, node pace, and node orientation.” Secondly, it protects data transmissions to achieve the highest level of security with the least amount of complexity. Finally, the NS-3 simulator shows how the proposed secure cross-layer protocol is effective than other protocols regarding control overhead, packet delivery ratio, and end-to-end delay. It runs extensive simulations based on the density of UAVs, packet rate, and constant bit rate connections. Improvements may be seen in the simulation results when the routing overhead latency is reduced and energy consumption, whereas End to End Delay and PDR of SRFRM are increased in contrast to existing protocols. The simulated results show improvement as it decreases the delay incurred in SIRFRM is 24%, and routing overhead is 19%, where the PDR of SIRFRM is increased by 32% in comparison with existing protocols.
