摘 要: 水下传感器网络中节点间通信的参数优化研究是基础,而数据包长是影响通信性能的重要指标,因此要选择一个最优的数据包长使节点的通信性能最优是一个关键问题。该文首先针对水下传感器网络的高时延、高能耗、高误码率特性构造体现通信性能的模型作为优化目标,然后引入QICA算法以离线的方式整定出多种环境和条件下最优通信参数组合,最后从理论上和仿真实验中结合数值分析论证了该算法的有效性和实时性。

Abstract:Parameter Optimization of inter-node communication is the foundation of underwater sensor networks. The packet length is an important indicator of the impact of communication performance.So you want to select an optimal length packets to make optimal node communication performance, which is a critical issue. Firstly this paper in connection with underwater sensor networks for high-latency, high-energy, high bit error rate characteristics of the model structure reflects the communication performance as the optimization target.Then introduce QICA algorithm and calculates the optimal solution in offline packet length.Finally, numerical analysis demonstrates the effectiveness of the algorithm ,real-time theory and simulation experiments.
Key words: Underwater Sensor Networks; data packet size; QICA
