Abstract

A method for determining a node decision threshold in a bidirectional molecular communication network based on network coding comprises the following steps: step 1, calculating the number of molecules received by a source node S1 and a source node S2 in a 2nth time slot based on a network coding strategy; step 2, respectively establishing a hypothesis test model and an optimal threshold detection rule at the relay node R and the source nodes S1 and S2 to obtain an average bit error rate of the nth bit transmitted by the bidirectional molecular communication network based on network coding; and step 3, minimizing the average bit error rate under the SNM and DNM conditions by using a PSO algorithm so as to determine the decision threshold of each node of the bidirectional molecular communication network under the SNM and DNM conditions. The invention mainly develops a node decision threshold method which can be used for determining a bidirectional molecular communication network with a low bit error rate.

Description

technical field [0001] The invention relates to biotechnology, nanometer technology and communication technology, and relates to a method for determining a node decision threshold in a two-way molecular communication network based on network coding. Background technique [0002] With the rapid development of nanotechnology in recent years, new molecular communication networks have gradually entered the public's field of vision. Due to their biocompatibility and energy-saving technology, they are considered to be a promising communication mode in the field of nanoscale communication between nanomachines. One of the most important applications of molecular communication networks in the field of biomedicine is drug delivery in the human body, which lays the foundation for the networking of bionanomaterials. However, the communication distance of a single nanomachine is limited. In order to improve the communication range, the cooperative transmission of one or more relay nanoma...
