Adaptive Transmission Range Control for Electromagnetic-based Broadcasting in Nanonetworks

Nanocommunication is a new paradigm that allows nanomachines to communicate using mechanisms, such as molecular-based, electromagnetic-based, acoustic-based, and nanomechanical-based mechanisms. A nanonetwork is formed of tiny nanomachines with limited sensing, computational, storage and power capabilities. In forming well connected nanonetwork, coverage area or transmission range of nanonodes should be carefully tuned according to the network density. The aim is to minimize contentions while maintaining good latency and high throughput under different nodes densities. However, selecting dynamically and in a distributed manner the best suitable range for each node is a difficult issue. In this paper, an adaptive transmission range of electromagnetic-based communication mechanism is introduced. Simulations are conducted using Nano-Sim, and results are reported to show the efficiency of the proposed approach in terms of throughput and latency according to the network density
