Abstract
In geographic routing protocols for flying Ad hoc networks (FANETs), unmanned aerial vehicles need to maintain real-time positions of their one-hop neighbor nodes to make effective routing decisions. Periodic broadcasting of Hello packets that involve real-time geographic position coordinates of nodes itself is a popular method to maintain neighbor information table. However, the traditional periodic Hello mechanism ignores node mobility, network connectivity and traffic type, thus causes temporary communication blindness (TCB). To address this problem, an adaptive Hello mechanism (AHM) for geographic routing is proposed in this paper. The Hello period of working nodes is calculated according to the real-time relative characteristic values between the node and its upstream node, and the Hello period of idle nodes adopts a fixed value according to the movement characteristics relative to all neighbor nodes. Moreover, the AHM is integrated into the widely-used greedy perimeter stateless routing (GPSR) protocol, and is compared with the original GPSR in simulation. The results show that AHM significantly mitigates the TCB problem and gains a high packet successful transmission rate without producing more routing overhead.
