Abstract
With the rapid penetration of nanonetworks-based molecular communication (MC), many studies potentially investigated the influence of nanoparticles on the performance of transmission/delivering nanoscale information. In this study, we analytically investigate a new collision/adhesion-based MC framework by considering the inter-nanoparticles near field interaction such as van der Waals forces and the electronic structure of the nanoparticles in terms of hardness coefficient. In this context, we derive a closed-form expression of the required velocity for two nanoparticles to physically contact in terms of near field forces and hardness coefficient of the nanoparticles. In a consequence, we study the performance of the proposed MC framework in intra-body nervous system nanonetwork. Then, we evaluate the performance of the proposed nanonetwork-based mobile ad hoc molecular nanonetwork metrics of interest such as average packet delay, network throughput and sustained traffic rate. The numerical results reveal that when the mutual interaction between molecules is attractive force, it generally provides a better performance; more specifically, it can deliver information with lower delay than repulsive force although the hardness coefficient of nanoparticles is small.
