A Novel Adaptive Cross-layer Broadcasting Protocol NABP for Three-dimensional Flying Ad Hoc Networks

To alleviate the broadcast storm problem caused by blind flooding, a Novel Adaptive Broadcasting Protocol (NABP) for three-dimensional Flying Ad hoc NETworks (FANETs) is proposed. NABP adopts the cross-layer design, which lets routing layer share the received signal power information at MAC layer while still maintaining separation between the two layers. The additional transmission range that can benefit from rebroadcast is calculated according to the received signal power, which is applied to dynamically adjust the rebroadcast probability. NABP reduces the redundant retransmission and the chance of the contention and collision among neighboring nodes in the networks. The simulation results demonstrate preliminarily that NABP improves the saved rebroadcast and reduces the average end-to-end delay and the average number of packet loss per node at the expense of a little throughput, which all compare NABP with flooding+802.11 and fp-flooding+802.11.
