Abstract : Nanocommunication is a new paradigm that enables connectivity at the nanoscale through molecular, electromagnetic, acoustic, or nanomechanical mechanisms. The general context of this thesis concerns wireless nanosensor networks and nanonetworks on chips. More precisely, the thesis deals with interconnection architectures and communication protocols in the terahertz band. The existing network architectures and communication protocols should be revisited taking into account the communication mechanisms at the nanoscale.First, dissemination approaches in the context of wireless nanosensor networks are addressed. An efficient broadcasting approach is presented and the simulation performance results with Nano-Sim and NS3 show that the proposed scheme is superior to flooding, especially in the cases of excessive broadcasts.Second, we investigated the impact of transmission ranges on the performance of broadcast mechanisms based on electromagnetic waves at the nanoscale. Adaptive transmission range of electromagnetic-based communication approaches are proposed. Simulations are conducted with fixed and adaptive transmission ranges to show the efficiency of the proposed approaches in terms of throughput and latency according to the network density.The third part addresses the hypothesis of using EM-based nanonetwok as an on-chip interconnect for SoCs.
