A New Routing Scheme for Multi-cluster Flying Ad hoc Networks

Recently, the applications of remotely aerial nodes, e.g., unmanned aerial vehicles (UAVs) are growing swiftly for numerous civil and military areas by creating flying ad hoc networks (FANETs). Due to increasing number of UAVs and fast changing topology, FANETs require an adaptable, delay-bounded, and reliable communications among UAVs while maintaining the desired network quality of services. Multi-cluster FANETs handle resource scarcity problems and optimizes network performances over single cluster by efficient management of UAVs. In this research, IEEE 802.15.4 MAC protocol is considered in multicluster FANETs for both beacon enabled and beacon-less modes among UAVs communication. Therefore, an efficient routing strategy is presented with two mobility models, e.g., Random Way Point (RWP) and Gauss Markov (GM). In addition, the performance analysis of different network parameters (i.e., jitter, throughput, packet delivery ratio, end to end delay, and normalized routing load), are illustrated for four routing protocols (AODV, DSR, DSDV, and OLSR).
