| 摘 要： | 根据免疫系统B细胞和T细胞模型，建立人工免疫系统与无线传感器网络间的相似关系，提出一种邻域节点选择算法，以判断传感器节点是否被激活。由于事件信息传递到汇聚节点会产生偏差，利用时空相关理论和自适应最小均方误差滤波算法，建立偏差与激活节点数目及偏差与节点通信频率之间的关系，确定传递事件信息所需最少激活节点数和最佳通信频率。不同条件下仿真结果表明，这种无线传感器网络优化策略能起到减少节点数目、降低通信频率及节约能耗的效果。

| Abstract: | According to the B-cell and T-cell model of immune systems,the similarity between artificial immune system and wireless sensor networks is compared.A neighborhood node selection algorithm is proposed to decide if a sensor node is activated or not.Considering the feature of event estimation distortion at the sink node,the relations between distortion and number of activated sensor nodes as well as distortion and reporting frequency are constructed by the spatial-temporal correlation and adaptive least mean s... |
