Method for determining bit error rate of diffused multicast molecular communication network

Abstract

The invention relates to a method for determining a bit error rate of a diffused multicast molecular communication network, which comprises the following steps: a first step, establishing a diffused multicast molecular communication model and analyzing a bit error rate in a hop link, wherein in a binary molecular communication model, whether a sender nanomachine is used for releasing molecules isused for representing different bit information; if the currently transmitted bit is 1, a specified type of molecules are released into a biological environment, and the molecules move in Brownian form in the medium; if the transmitted bit is 0, the molecules are not released; a second step, analyzing the bit error rate of the multicast molecular communication network under the relay strategy thateach nanomachine adopts different types of molecules; a third step, analyzing the bit error rate of the multicast molecular communication network under the relay strategy that each nanomachine adoptsdifferent types of molecules and proposing a method of adjusting the threshold to effectively reduce the interference when the same type of molecules are transmitted between the parallel relay nanomachines. The method effectively resolves the bit error rate and reduces the interference.

Description

technical field [0001] The invention relates to biotechnology, nanometer technology and communication technology, is a diffuse multicast molecular communication network, and mainly aims at a bit error rate determination method. 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. Among them, the small nanoscale (10 -9 m) devices are called nanomachines, which are mainly responsible for performing some simple tasks such as calculation and perception. Due to the limitations of the size and capability of nanomachines, a single nanomachine is not enough to complete more complex tasks. Therefore, in a molecular communication network, it is necessary to organize multiple nanomachines in a distributed manner and coordinate with each other, so that information can be transmitted efficiently. Wider range and higher accuracy. Based on the practicality of ...
