This material is based on work in progress. With the advance of electronic and Micro Electro Mechanicals Systems (MEMS), swarm of communicating and collaborating micro-robots became very attractive. In this paper, we revisit Vouivre, a nano-wireless simulation library we previously developed. Using the specificities of the Terahertz radio channel as a foundation, we discuss and present an implementation that allows simulation of a larger number of concurrent transmissions between an even larger number of individual elements
