“…In order to improve the performance of cluster-based networks, many studies have focused on the method of adopting various access schemes for intra-cluster and inter-cluster communications. In [12], a cluster-based multichannel MAC mechanism based on time division multiple access (TDMA) is proposed for VANET. In the proposed mechanism, vehicles which move in the same direction are grouped into clusters, and CH is responsible for the transmission slots assignment.…”

“…An optional solution to the above challenge is the method of adopting different access schemes for intra-cluster and intercluster communications [12][13][14]. However, these schemes are all rely on single CH in each cluster, which will inevitably lead to the increasing overload and premature death of CH when the number of CMs increased.…”

Unmanned Aerial Vehicle (UAV) ad hoc network has achieved significant growth for its flexibility, extensibility, and high deployability in recent years. The application of clustering scheme for UAV ad hoc network is imperative to enhance the performance of throughput and energy efficiency. In conventional clustering scheme, a single cluster head (CH) is always assigned in each cluster. However, this method has some weaknesses such as overload and premature death of CH when the number of UAVs increased. In order to solve this problem, we propose a dualcluster-head based medium access control (DCHMAC) scheme for large-scale UAV networks. In DCHMAC, two CHs are elected to manage resource allocation and data forwarding cooperatively. Specifically, two CHs work on different channels. One of CH is used for intra-cluster communication and the other one is for inter-cluster communication. A Markov chain model is developed to analyse the throughput of the network. Simulation result shows that compared with FM-MAC (flying ad hoc networks multichannel MAC,FM-MAC), DCHMAC improves the throughput by approximately 20%-50% and prolongs the network lifetime by approximately 40%.
