This work presents a performance analysis of a decode-and-forward (DF) relay-assisted diffusion-based molecular communication system consisting of one nanotransmitter. one nanoreceiver and one nanotransceiver acting as relay. We consider cases using one molecule in our two-hop relay network (1M2H). and using two molecules (2M2H). https://www.oxfordshopes.shop/product-category/ladies-tops-day/
