摘要：

Terahertz based in-vivo Wireless NanoSensor Networks (iWNSNs) is a novel sensor network using electromagnetic waves in terahertz band as carrier and nanotechnology work in human body. Due to the different propagation characteristic of in-vivo terahertz channel and the limited resource of nano device, current MAC (Medium Access Control) protocol cannot be applied to Terahertz based iWNSNs. In this paper, a MAC protocol based on energy scheduling, called ES-MAC, is proposed. This protocol adopts nano energy harvesting system, designs a reward function based on the amount of transmitted data and the priority of data. Nano sensor nodes adopt Sarsa learning algorithm to make dynamic channel access decision according to their status. Simulation results show ES-MAC protocol can decrease average end-to-end delay and prolong lifetime of the network while providing differentiated services.
