International audience The race for the miniaturization of electromechanical equipments has seen tremendous progress in recent years. In this context, nano-wireless networks composed of a large number of tiny equipments concentrated in a reduced area findimultiple applications in the field of multi-core processors, programmable matter or nano-sensors networks. In order to support wireless communication between numerous millimeterscale nodes, the radio access management protocol, a Time-Spread On-Off Keying (TS-OOK), has been proposed to operate under high density, scarce energy and miniaturized network node constraints. Despite of all the advantages provided by TS-OOK protocol, it suffers of two main drawbacks: an unbalance treatment of the active communications and a lack of adaptability. We propose to correct these defaults by adding Adaptive Symbol Rate Hopping mechanism to TS-OOK giving birth to a new protocol called Adaptive Symbol Rate Hopping TS-OOK (ASRH-TSOOK), which allows to better share the system bandwidth and to automatically readjust the radio allocation to the system load. Our protocol is based on a solid probabilistic formulation providing an accurate and a slight procedure to dynamically adjust the communication symbol rate according to the estimated system load.
