An adaptive routing protocol in flying ad hoc networks

Abstract

Nowadays, ad hoc networks play a vital role in wireless communication. It is a temporary network to relay the data between nodes. Ad hoc network is divided into different types such as MANET, VANET & FANET. FANET is a combination of MANET and VANET. In FANET, routing is a big challenging issue due to unique characteristics like dynamic topology, frequent changes of link quality, mobility of UAV nodes, etc. Reliability of routes is also a real challenge due to the very high mobility in FANET. In this research work, we have introduced an adaptive routing protocol, PF-WGTR - A predicted future weight-based routing scheme for FANETs that considers the node’s existing and upcoming values of assured parameters to determine the reliable routing path. This proposed routing protocol assigns weight to every node in the network by calculating the node’s future. Depending on the predicted future weight of every node in a network, the communicating nodes can establish a reliable path that persists for a long time. This adaptive, future prediction-based routing scheme ensures better data delivery with minimum overhead and optimized energy consumption in all conditions compared with the existing routing protocols. The NS-2 simulator is used to compare the proposed routing protocol with previous protocols in terms of FANET parameters. Finally, the simulation results show better performance than the existing works.
