论文摘要
在本文中，考虑了基于能量收获（EH）解析（DF）继电器的合作通信网络，该中继（DF）继电器使用带有收获商店使用的缓冲区（HSU）架构从氛围中收获能量。提出了基于节点传输优先级的数据包的传输路径的机会性路由（或）协议，以改善该网络中的数据传输。此外，提出了基于状态过渡矩阵（STM）的算法以获得候选广播节点集的概率分布。基于概率分布，使用离散的连续状态马尔可夫链（DCSMC）模型的能量缓冲器中能量限制分布的存在条件和理论表达式。此外，借助存储在缓冲区中的能量的限制分布，获得了网络中断概率和吞吐量的闭合形式表达式。已经进行了许多实验以验证衍生的理论表达式。
In this paper, a cooperative communication network based on energy-harvesting (EH) decode-and-forward (DF) relays that harvest energy from the ambience using buffers with harvest-store-use (HSU) architecture is considered. An opportunistic routing (OR) protocol, which selects the transmission path of packet based on the node transmission priority, is proposed to improve data delivery in this network. Additionally, an algorithm based on state transition matrix (STM) is proposed to obtain the probability distribution of the candidate broadcast node set. Based on the probability distribution, the existence conditions and the theoretical expressions for the limiting distribution of energy in energy buffers using discrete-time continuous-state space Markov chain (DCSMC) model are derived. Furthermore, the closed-form expressions for network outage probability and throughput are obtained with the help of the limiting distributions of energy stored in buffers. Numerous experiments have been performed to validate the derived theoretical expressions.
