The invention discloses a method for determining bit error rate and mutual information of multi-hop mobile molecular communication network, and the method comprises the following steps: step 1, establishing a multi-hop mobile molecular communication network model, and on this basis, obtaining a mathematical expression of the number of molecules received at a relay node and a destination node of a two-hop mobile molecular communication network under the DTM condition; step 2, establishing a hypothesis test model at a destination node, obtaining a detection threshold value at the destination node under the DTM condition by using a maximum posterior probability MAP detection method, and obtaining a bit error rate of the multi-hop mobile molecular communication network and a mathematical expression of mutual information; step 3, establishing a bit error rate and mutual information determination method of the two-hop mobile molecular communication network under the STM condition; and 4, establishing a bit error rate and mutual information determination method of the multi-hop mobile molecular communication network under the DTM and STM conditions. The invention provides a low bit error rate and high mutual information determination method for a multi-hop mobile molecular communication network.
Description
technical field [0001] The invention relates to the communication technology of the nanometer network, and relates to a method for determining the bit error rate and mutual information of the multi-hop mobile molecular communication network. Background technique [0002] Nano-network is a new emerging interdisciplinary scientific research field, covering nanotechnology, sensing technology, information computing, communication technology and other fields. At present, many related technologies of nano-networks (such as nano-machine architecture, information perception, data fusion, communication technology, etc.) need to be further studied. As one of its core technologies, the research on data communication technology of nano-network is still in the initial stage. Because mobile molecular communication has characteristics different from traditional communication technologies and is suitable for many specific application environments (such as drug delivery in the human body, h...
