摘要:

在本文中,我们提出了一对生物纳米机器,发射器和接收器之间的通信协议,建立在水环境中的分子通信。在我们的建议中,接收器,作为一个控制节点,发送一个连接设置信号到发射器,这stokes分子,开始分子传输。由发射器发射的分子在环境中传播,并通过其受体被接收器吸收。当接收器吸收所需数量的分子时,它会释放一个拆除信号,通知发射器停止传输。所提出的协议实现了一个双向的通信,通过使用一些技术最初设计的TCP。事实上,该协议是面向连接的,并使用类似TCP的探测,以找到一个合适的发送器和接收器之间的传输速率,以避免接收器拥塞。然而,与TCP不同的是,不使用显式分段,因为它们会由于大延迟而降低通信吞吐量,这是分子通信的特征。因此,所提出的协议使用隐式压缩,并且由接收器发送反馈信号以抑制发射器处的传输速率,即,明确的负面反馈。我们还提出了一个广泛的模拟活动的结果,用于验证所提出的协议,并适当的尺寸的主要协议参数。

英文摘要:

In this paper, we present a communication protocol between a pair of biological nanomachines, transmitter and receiver, built upon molecular communications in an aqueous environment. In our proposal, the receiver, acting as a control node, sends a connection setup signal to the transmitter, which stokes molecules, to start molecule transmission. The molecules transmitted by the transmitter propagate in the environment and are absorbed by the receiver through its receptors. When the receiver absorbs the desired quantity of molecules, it releases a tear-down signal to notify the transmitter to stop the transmission. The proposed protocol implements a bidirectional communication by using a number of techniques originally designed for the TCP. In fact, the proposed protocol is connection-oriented, and uses the TCP-like probing to find a suitable transmission rate between transmitter and receiver so as to avoid receiver congestion. Unlike the TCP, however, explicit acknowledgments are not used, since they would degrade the communication throughput due to the large delay, a characteristic feature of molecular communications. Thus, the proposed protocol uses implicit acknowledgments, and feedback signals are sent by the receiver to throttle the transmission rate at the transmitter, i.e., explicit negative feedbacks. We also present the results of an extensive simulation campaign, used to validate the proposed protocol and to properly dimension the main protocol parameters.
