Abstract Multi-hop wireless networks are designed to support long-distance, cost-effective communication with high data transfer rate. Maximizing network throughput is one of the critical goals while developing a multi-hop wireless network. Efficient routing and scheduling techniques enhance throughput and reduce delay, which improves the overall network performance. This paper proposes a transmission group-based routing and scheduling (ππΊπ π) technique implemented in centralized and distributed ways. The main aim of this study is to enhance the performance of 3D multi-hop wireless networks in terms of throughput and delay. Users establish a routing path to the base station based on the minimum angle-based IM selection process. In ππΊπ π, multiple groups are formed for all the IM links of the routing path; links are included in the same group if they do not interfere mutually. All the links of a group are transmitted concurrently, which maximizes throughput and minimizes delay. The proposed ππΊπ π technique dramatically improves network performance by increasing concurrent transmission and throughput. The effectiveness of the proposed techniques is demonstrated through extensive simulation.
