摘要

背景:由于环境的影响,信号在传输路径中会突然消失,有时会丢失,导致目的节点接收到的信号较弱。协作通信网络(CCN)克服了这一问题,提供了更好的频谱效率。源节点和helper节点都将信息发送给接收者。尽管有许多优点,但这种网络也有一些局限性。由于网络中使用了多个辅助节点,因此通过功率、能量或中继选择优化来提高系统效率是非常可取的。考虑到这一关键的优化要求,所提出的工作提出了系统的最优功率分配。方法:采用被膜群优化方法提高系统参数、符号错误率、中断概率和误码率。分析采用两种中继协议,即放大转发协议(AF)和差分AF协议(difff -AF),并采用两种组合方案:选择组合(SC)和最大比例组合(MRC)。结果:将所得结果与粒子群算法(PSO)、黑寡妇优化算法(BWO)和传统的等功率分配方法(EPA)等元启发式算法进行了比较。结论:仿真结果表明,所提算法相对于时间更短的算法,提高了系统参数。

Swarm Algorithm-based Power Optimization in Cooperative Communication Network
Background: Due to the environmental effects, the signal fades abruptly and is sometimes lost in the transmission path, which results in weak signal reception at the destination node. The Cooperative Communication Network (CCN) overcomes this problem and provides better spectral efficiency. The source node and the helper node both send the information to the receiver. In spite of many advantages, there are some limitations to such networks. Improving the system efficiency by power, energy, or relay selection optimization is quite desirable as multiple helper nodes are used in the network. Considering this crucial requirement of optimization, the proposed work presents optimal power allocation of the system. Methods: Here, tunicate-swarm optimization is implemented to improve the system parameters, symbol error rate (SER), outage probability, and bit error rate (BER). Two relaying protocols are used for analysis, i.e., Amplify-and-Forward (AF) and Differential AF (Diff-AF), with two combining schemes: Selection-Combining (SC) and Maximal-Ratio-Combining (MRC). Results: The results obtained are further compared with other metaheuristics algorithms, such as Particle-Swarm-Algorithm (PSO), Black-Widow-Optimization (BWO), and the traditional method of Equal-Power-Allocation (EPA). Conclusion: The simulation result shows that the proposed algorithm improves the system parameters compared to algorithms with less time.

期刊介绍: International Journal of Sensors, Wireless Communications and Control publishes timely research articles, full-length/ mini reviews and communications on these three strongly related areas, with emphasis on networked control systems whose sensors are interconnected via wireless communication networks. The emergence of high speed wireless network technologies allows a cluster of devices to be linked together economically to form a distributed system. Wireless communication is playing an increasingly important role in such distributed systems. Transmitting sensor measurements and control commands over wireless links allows rapid deployment, flexible installation, fully mobile operation and prevents the cable wear and tear problem in industrial automation, healthcare and environmental assessment. Wireless networked systems has raised and continues to raise fundamental challenges in the fields of science, engineering and industrial applications, hence, more new modelling techniques, problem formulations and solutions are required.
