Wireless Sensor Networks (WSNs) enable a wide range of application that necessitates advances in protocol performance, security, and energy efficiency. Medium access control (MAC) layer protocols are essential in providing these advances due to their functionality domain in resource allocation and utilization. The contribution of this paper is the proposal of a novel cluster based hybrid time division multiple access (TDMA) scheduling MAC for Mobile-WSNs, to support non-uniform time mobility for real time applications. The hybrid approach improves scalability by utilizing the cluster-based approach while it also enables to support varying mobility conditions in the network. The paper presents the design, implementation and performance evaluation of the hybrid TDMA scheduling algorithm called Hybrid-Green Conflict Free (H-GCF) for intelligent Mobile-WSN applications. H-GCF combines the strength of Green Conflict Free (GCF) and Multicolor-GCF (M-GCF) while counterbalancing their weaknesses. H-GCF works using M-GCF under static and low mobility conditions and using GCF under high mobility conditions. As seen from the results, these distinctive features of H-GCF make it energy-, delay-, and throughput efficient with good scalability under fixed- and random- mobility conditions.
