摘要：

为提高集成网络节点的部署效率,在考虑节点交叉覆盖及节点间干扰等约束条件下,基于改进人工蜂群算法,提出一种集成网络节点位置部署算法。基于网络节点的信号传输模型将节点部署问题转化为在保证节点高覆盖率与低干扰目标下的优化问题,利用改进人工蜂群算法对节点部署目标函数进行优化。仿真实验结果表明,该算法不但能够快速精确地找到全局部署最优位置,而且能够在保证射频标签最大覆盖率的前提下有效地降低节点间的干扰。

Abstract:

In order to improve the deployment efficiency of the integrated network nodes,an integrated network node location deployment algorithm is proposed based on the improved Artificial Bee Colony(ABC) algorithm when considering the cross coverage of nodes and interference between nodes.In the deployment algorithm,the deployment problem of network nodes which is based on the signal model is converted into the optimization problem of ensuring high coverage and low interference of nodes,and the improved ABC algorithm is used to optimize the objective function of node deployment.Simulation results show that the algorithm can not only find the best position for global deployment quickly and accurately,but also effectively reduce interference between the integrated network nodes under the premise of the largest coverage of Radio Frequency Identification(RFID) tags.

Key words: integrated network node, Radio Frequency(RF) model, deployment optimization, global cross mechanism, improved Artificial Bee Colony(ABC) algorithm
