The development of nanotechnology in recent years makes intra-body flow-guided nanonetworks more feasible. Monitoring different biomarkers, detecting infectious agents, locating cancerous cells, delivering drugs accurately and other medical application are under study. Taking the consideration of the laminar blood flow feature of blood vessels, where concentric layers of blood with different velocities move along in the length of the vessels and the central layer (i.e., lane) has the highest velocity, this paper proposes a central high-speed lane routing protocol, which selects nano-nodes with high speed in the central layer of blood flow and forms a directional relaying chain for other non-central nano-nodes. This protocol helps improve the throughput and success rate of the nanonetworks with high node density and the utilization and life cycle of the nano-nodes. The protocol is simulated under the blood vessel model combined with laminar movement model in Nano-Sim platform, and has been proven its great performance.
